START-UP

EPISODE 5

Chul-san, what's with him?

Hey, what's going on?

The date went well. Why the knitting?

Is something bothering you?

Hey!

-Chul-san.
-Yes.

-Nothing.
-Gosh.

What is it? Tell us.

Nevermind.

Jeez, you're doing it again.

Just tell us.

I asked Dal-mi

-why she likes me.
-What did she say?

I bet she has low standards.

Sorry.

First of all, you're…

my first love.

"First love"?

Technically, that would be Han Ji-pyeong.

So I asked her again why she likes me.

Your letters

comforted me for a long time.

That was also Han Ji-pyeong, not you.

Did she say anything about you?

My hands.

You have nice, big hands.

Just my hands, nothing else.

-Do-san.
-Yes?

When humans switched from all fours

to two limbs,
their brains started to grow.

Why? The other two limbs had
nothing to do, so they became hands.

The use of hands
led to the development of the human brain

and toolmaking,
thus establishing cultures and histories.

What's your point?

Jeez, a fellow engineering major
should understand him.

He's trying to say
that it's not "just" your hands.

The hands are everything.
Isn't that what you mean?

That's right.

MAN IS MOST INTELLIGENT
BECAUSE HE HAS HANDS

Yes! He held my hand.

What are you talking about? What about it?

When In-jae said to Do-san…

Who do you choose, me or Seo Dal-mi?

Do you know what he said?

Will you be the CEO of Samsan Tech?

Then he reached out his hand to me,
not In-jae.

Grandma.

That hand…

His hand

was the coolest thing ever.

You're weird. How cool could a hand look?

It looked very cool.

I'm a nobody.

Why hold my hand instead of In-jae's?

At least she likes my hands.

I'm a nobody.

Right?

Grandma.

I keep getting more ambitious.

I started this because I wanted to
win against In-jae because of dad.

Now, I'm getting really ambitious.

I know that she's too good for me,

but I keep wanting more.

I keep getting more desperate.

A SPRINT-LIKE EVENT
WHERE PARTICIPANTS TEAM UP

TO CREATE A SOFTWARE BUSINESS MODELS

SAND BOX 12TH HACKATHON

The next two days will be hell.

But not for me. It's none of my business.

Gosh.

After participating as a mentor
for three days last year,

I was bedridden for four days.

It was exhausting, stressful,
and not at all rewarding.

It's awful, isn't it?

Mr. Han?

Mr. Han?

Oh, where did he go?

ROOM 801

Here you go.

Find table 36.

Whenever you get a new team member,

send me their QR code.

Sure, got it.

Help yourself to the snacks.

You may eat as much as you like…

Hey, here.

Put some in your pocket, too.

They have awesome snacks here.

Hey, talk about motivation.
It'd be amazing to eat this every day.

Now, I'm dead serious about Sand Box.

I want to live here forever!

Hey, put them in here.

Do-san.

Hey.

Bend down.

Don't share these gummy snacks, okay?

They'll be gone in no time.

Okay.

Ms. Seo, we need another team member.

-Yes, we do.
-What are we looking for?

For our founding members,
I believe a good personality

is more important than fancy credentials.

I want someone who is motivated.

A natural-born problem solver
who is focused and persistent.

Someone who is resilient and
springs back easily. You get the idea.

Do-san. Where did Do-san go?

-How much did you tell her?
-Sorry?

Tell me. How much did Dal-mi find out?

Which part are you worried about?

The fact that I'm not a hotshot?

Or that the letters
from her first love were fake?

She knows about the letters?

No, not yet.

Was she very disappointed
that you're not a hotshot?

No, it actually made her happy.

It made her happy? She wasn't angry?

No.

What about me?
She doesn't think I'm weird?

I participated in tricking her
and even led it.

-She must be dying to know why I did it.
-Mr. Han.

She hasn't said a word about you.

-Really?
-Yes.

You don't have to lend me
your car or watch.

-You don't need to worry--
-How can I not?

You and Dal-mi are on the same team now.
Hold this for a second.

On top of that,
even her sister is at Sand Box now.

She'll be devastated if her sister gets in
and she doesn't.

-What are you doing?
-My question exactly.

What am I doing right now?

I can't believe I have to wear this
when I should be raising funds.

And a hackathon mentor?

Will there be many reporters?

I don't want them to take pictures of me.

You've done enough. I'll take care of it.

You're scaring me.
That's the scariest thing I've heard.

What have you been doing all this time?

If I were Yong-san or Chul-san,

I'd ask you to compensate me
for the past two years of my life.

What? Are you offended?
Does that piss you off?

Yes, a little.

What's that?

No, that's…

You don't get to be angry
because it's a fact.

I'll give you a chance to get angry
if you get into Sand Box.

My blood sugar's dropping.

This is mine.

Wait, let me see.

What's with him?

Hey, Do-san!

I looked everywhere for you.

Hello, Mr. Han.

I actually wanted to ask you something.

Well, I'm…

Right now…

What's up, Dong-cheon?

-What's going on?
-Pardon?

You need me? Excuse me for a second.

-Hey.
-Something's going on?

What is it? What's the matter?

-What? You're a mentor?
-Gosh, hey.

I see. We should hurry.

Come on. Let's go. Tell me what happened.

I see. You should've told me earlier.

What were you going to ask him?

Just some stuff.

Let's go.

I see.

I'm sorry. You should've called.

Why tell me now…

Gosh, this is nuts.

What is going on?

Is it something serious?
Did I make another mistake?

This won't do.

Hold this for a second.

Hey, take off your jacket.

-Dong-cheon.
-Yes?

You should be a mentor.

What? Why should I… No, hold on!

-Why should I be a mentor?
-I'm counting on you.

What? What do you mean? Sir.

Hey.

Look who it is.

Kim Yong-san, Lee Chul-san.

-Hyeon, Jeong!
-Hyeon, Jeong!

Wow, how long has it been?

I didn't expect to run into you here.

Same here. Good to see you guys.

My gosh, Hyeon.
You look even more stylish now.

Come here, buddy.

Jeong, you're here, too.

Do you guys have a team now?

Yes. Luckily, we were able to team up
with the best team.

-The best team?
-The best team?

INJAE COMPANY

Are those two in colorful clothes
also developers?

Oh, them. Yes, they're twins.

They're top-notch AI developers.

-Top-notch?
-Yes.

Why are they here? They're not interested
in starting a business.

People call them hunters.

Hunters? As in "hunter-gatherer"?

Yes. They've been participating
in all sorts of contests

and hackathons for about two years now.

They're only after the cash prize.
They're not launching a start-up.

It's like a dine and dash.

Those jerks demotivate people

who desperately need money
to launch their start-up.

They've probably won
hundreds of millions of won.

Sounds like they're quite skilled.
And they're pretty stylish for developers.

Hold on a second.
"Pretty stylish for developers"?

Ms. Seo, I don't like the sound of that.
Ms. Seo?

Then what about us? What are you implying?

Jeez.

Fine, I admit
that they beat us on that front.

But they don't care about
launching a start-up.

And we're the only CODA winners here.

Yes! They're only locally famous,
but we're global.

They've been global since college.
They went to MIT.

Whose side are you on?
Stop stirring things up.

That's impressive.

Don't be intimidated.
Their concept is totally different.

Yes. Academic credentials come second.
We'll showcase our high integrity.

Right, Ms. Seo? What?

-We need one more person.
-Anyone else?

-Let's talk outside.
-Sure.

Excuse me, coming through.

We need someone with such credentials.

Someone with impressive credentials.

SAMSAN TECH

Oh, my.

This is so cool.

All our past experiences show up
as soon as you scan the QR code.

I see.

SEO DAL-MI
HIGHEST EDUCATION LEVEL: HIGH SCHOOL

-Do-san, Yong-san.
-What?

Did you know
Seo Dal-mi didn't go to college?

She didn't?

Let's go ask Won In-jae to take us back.

The teams aren't finalized yet.

No. Seo Dal-mi is our CEO.

Do you really think we should let
a high school graduate be our CEO?

People will think
we're a joke because of her.

You sure you don't think that?

Me?

I don't waste my time with people
who think they can look down on others.

But other people do.

I don't look down on her.
Come on. You know how I am.

All right, then.

Don't worry about what people say.
We just need to be confident.

I was scared for a second.

He's become charismatic.

You're gorgeous.

I hope you join our team.
You'll brighten up the entire office.

I guess you prioritize looks
over experience.

But you know what?

I also prioritize looks.

Sa-ha, you're exactly the kind of person
we're looking for.

We want someone
who's multifaceted enough to tackle

accounting, legal matters, and design.

So you want me to do the work
of three people?

No, not even if you beg me.

Who are you?

I'm Seo Dal-mi, the CEO of Samsan Tech.

I'm here because of your experience,
not your looks.

I won't be one of those CEOs
who never work.

And I won't expect you to wear many hats.

Just take care of the design for us.

-Have you been following me?
-Yes.

Don't be such a loser.

People will look down on you.
A CEO must not kneel down so easily.

No, people don't care about the fact
that I'm on my knees.

Rather,
this will make them look up to you.

Isn't that better for you anyway?

Decide while there's still some time left.

If you do it at the last minute,
you'll look desperate.

Why me?

Tell me your reason.
I'll make my decision after I hear it.

It's…

…a green light.

Hello.

What the...

Yes, have a seat over here.

I'll take that…

All right. Meet the developers
of Samsan Tech. Nam Do-san,

Lee Chul-san, and Kim Yong-san.

This is designer Jung Sa-ha.

I see, you're a designer.
We've met before, haven't we?

Right, we have.

-Really? Where did you guys meet?
-Oh, we were buying a book.

That book… What was it called?

Joining Sand Box Q and A.

Yes, there was only one left…

She kindly yielded it for 10,000 won and
we bought the last copy.

What? 10,000 won?

It was a sensible transaction
that satisfied both of our needs.

They say

even brushing shoulders means
you were meant to cross paths.

What a coincidence!
Who knew we'd all be founding members?

Stop.

Let's set some boundaries first.

Lame expressions such as "meant to be"
and "coincidence" are banned as of now.

It's not like I wanted to join this team.

I chose you guys
because I was pressed for time.

Samsan Tech…

What a horrible name.

This isn't my final destination.

I'm just making a quick stop, that's all.

Don't forget that.

I won't.

All right. Shall we get started, then?

Okay, everyone.

Now that you've finalized your teams,

we'll begin the hackathon.
You will be given 48 hours.

Work with your teammates

to come up with a new business model.

Feel free to use

Sand Box's data set, GPU, and API.

You are free to use as much
of our resources as you need.

GPU: GRAPHICS PROCESSING UNIT
API: APPLICATION PROGRAM INTERFACE

That's amazing. We can use everything?

"We'll open up our oil field.
Take all you need."

"Take it and make asphalt, nylon,
or whatever you want with it."

My gosh, how generous.
It sure is nice to play in a big pond.

Tell us the winner selection criteria.

We'll be looking at two things.

First, the ability to come up
with a feasible, practical business plan

within the limited amount of time
using the given resources.

Second,
the ability to pitch the idea to us

in just three minutes.

-Three minutes?
-Three minutes…

All right.

You may use all of Sand Box's data
however you need.

I hope you can all come up
with revolutionary ideas.

Good luck to all of you.

So what are you guys thinking?

Probably something service-related.

No, we're thinking of launching a service
based on machine learning.

Are you guys a tech-based team?

Yes, obviously.
Can't you tell from our name? Samsan Tech.

Oh, my God. This is like playing
the lottery.

Right? Aren't you happy that you chose us?

No. What I'm saying is, this isn't for me
because I never win the lottery.

Oh, I see.

Ms. Seo, I'm not trying
to belittle you or anything,

-but do you know what machine learning is?
-Hey.

Yes, I do.
Do-san explained it to me the other day.

It's a very romantic technology.

"Romantic"?

How did you explain it to her

to give her an impression
that machine learning is romantic?

-I'm curious.
-About what?

You. I want to know everything about you.

Your family, friends,

and the things you like.

I like…

designing artificial neural networks.

ANN: ALGORITHMS THAT MIMIC
HOW THE BRAIN PROCESSES DATA

-Have you heard of it?
-Yes, I have.

But I don't really know what it is.

Then…

What about machine learning?

Well, that too. I've heard of the term

but don't know what it is.

If that's the case… Here.

This is a computer.
Let's say his name is Tarzan.

He grew up on a deserted island,
so he's never seen a woman in his life.

But one day,

Jane arrives on the island.

He gives her a rock,
and she doesn't like that.

But when he gives her a flower,
it makes her happy.

I see.

He's never dated,
so he doesn't know what women like.

That's right. So Tarzan keeps on trying.

He catches a snake for her,
but she doesn't like it.

One day, he gives her a cute rabbit,
and that makes her happy.

She seems displeased when he yells,
but she likes it when he smiles.

While building such experiences,

he learns how to win Jane's heart.

I see. Hence the term, machine learning.

-You teach the machine to learn.
-Exactly.

You give the computer data
on various experiences.

It'll learn the data
through ANNs and predict results.

That's what I do.

Boring, right?

No, it was very interesting.

And cool.

-Tarzan?
-Jane?

Meta… Don't you know what a metaphor is?
A figure of speech.

No, I don't.
I always bombed my Korean exams.

I'm cringing so hard right now. Jeez!

How long will this chitchat last?

We've wasted 20 minutes already.

All right.

What kind of data set
can our Tarzan learn?

There's all kinds of data here.

Traffic accidents, fine dust levels…

-Even penmanship.
-Penmanship?

-It's a data set on handwriting.
-Jeonghan Bank?

Why would a bank have data on handwriting?

Of course, they would.
All the deposit, withdrawal, loan,

and power of attorney forms
are filled out by hand.

Same goes for handwriting forgery.

Sa-ha, you suddenly seem
totally unapproachable.

What?

You're too perfect.

SAMSAN TECH

Oh, hold on. I've got an idea.

-What's your idea?
-If we teach Tarzan

to distinguish forged handwriting
from authentic ones,

maybe he'll be able to detect forgery.

I can't guarantee it,
but I think it's doable.

But can that be a viable business model?

Of course, it can.

Hey, Dong-cheon.

Park Dong-cheon.

Jeez, who's calling my name
so desperately?

Park Dong-cheon! Hey!

Yes, Mr. Han. There you are.

-You pretended you didn't hear me.
-No, not at all.

About Samsan Tech…
Have they decided what to do?

Yes, I think so.

-Already?
-Yes.

You should've helped them out.

There was no need.
Their idea is pretty good.

Yeah, right. What's their idea?

Detecting handwriting forgery
using machine learning.

Hey, that's not a viable…

-Actually, that's not a bad idea.
-Right?

Who came up with the idea?

Seo Dal-mi, the CEO.

Seo Dal-mi?

-Handwriting…
-Yes, the data on handwriting

-can definitely be turned into…
-But…

There's a lot of interesting data sets.

What about distribution?
That's our specialty.

What about
Jeonghan Bank's handwriting data set?

Handwriting?

But what kind of business model?

That is up to the CEO to decide.

Handwriting data set? That's random.

Samsan Tech is planning to create
a service using that data set.

-What about it?
-I saw

Nam Do-san at Samsan Tech
flat out rejected you earlier.

-Hey, watch your mouth.
-We'll help you.

Let's go up against them.

Why should we?

Because it's fun.
Taking down the jerk who rejected you.

SAMSAN TECH

Shall we get started?

-Okay.
-Okay.

SAMSAN TECH

Let's be creative.

Why don't we design a new font?
The things that cost money…

Eight percent, right?

Right, the court.

-We did it.
-My gosh.

It's not collecting the data at all.

Shall we tweak the hyperparameter?

Okay, let's start over.

Why is the test set accuracy so low?

What is the problem?

Shall we change the activation function?

-Guys, I think--
-We're all busy now,

so save it for later.

Dal-mi, what is it?

Jane may prefer flowers,

but I prefer rocks.

What's she saying?

Flowers are useless on a deserted island.

With rocks, you can knock
fruits off trees and scare off wolves.

Right.

That's why I'd prefer rocks to flowers.

Hey, Do-san. Make sure you get her
a big rock, not flowers.

Everyone's taste is different.

Let's change the network structure.

-Now?
-Have you lost your mind?

We used this structure
when we were working with video data.

Handwriting data
has a totally different pattern,

so the same network won't work.

Let's completely redo it
and come up with a slimmer network.

Yes, that's exactly what I wanted to say.

Hey, that is a lot of work.

And once it's done, we can't undo it.

Still, we should try something new rather
than being stuck with the wrong answer.

If it doesn't work, we have to pack up.

Right.

Let's try it.

The kimchi doesn't taste
as ripe as it did last time.

I told you that you can let it ripen.

You put it in the fridge right away.

-Why are you blaming me?
-I'll take it out.

Goodness, the world is going to the dogs.

What is a full-fledged adult
doing with that toy?

Oh, dear.

What? Why…

What do we do? He must've heard you.

I didn't say anything.

Do you happen to know
where Mr. Nam Do-san lives?

-Who are you?
-I'm Alex.

I came all the way from San Francisco
to meet Mr. Nam.

Awesome pronunciation.

San Francisco?
Isn't that where Silicon Valley is?

I am

Do-san's dad… I mean, I'm his father.

-And this is…
-I'm his mother.

-What?
-Hello, it's nice to meet you.

I had to come to Korea for work,
so I came here to meet Mr. Nam.

I'm really sorry,
but Do-san isn't home at the moment.

Ouch! Where is he?

Shall I bring you something to eat?

SAND BOX 12TH HACKATHON
SAND BOX AUDITORIUM LIVE BROADCAST

I'm eating now. Don't worry.

Mother.

What are you doing here?
Weren't you transferring to the US?

I quit.

-Why?
-Like someone once told me,

I could only start the company
thanks to Dad.

I won't get any credit
even if I do well, so I quit.

I want to start over.

I see.

So you probably don't need
three years now.

What?

I'll be honest. At the moment,
I'm not as successful as In-jae is.

I admit it.
But In-jae is three years older than me.

So give me three years.

I'll outdo her by then.

Let's bet 10,000 won. What do you think?

So step up your game.

You have to get into Sand Box
for us to compete.

The developers on your team
seem totally lost.

You always make the wrong choices.

Choosing Nam Do-san
and also staying with Dad.

I wish you would shut up.

Let's wait and see.
Time will tell who made the bad choice.

You're right. Time will tell.

Right, we're also using
Jeonghan Bank's handwriting data set.

I thought you should know
because that's only fair.

We have the result.

-You have the result?
-I was just about to text you.

What's the result? Tell me.
What's the accuracy like?

It's over 99.8 percent.

Thank goodness.

Dal-mi, are you crying?

Thank you.

Thank you so much.

Looking for something?

I'm trying to find

this little kid among the participants.

This kid is here?

She's participating in this hackathon.

She is?

-Seriously?
-Yes.

Did you invite her?

Gosh, no. I found out about it by chance.

She probably has no idea

she was the inspiration behind Sand Box.

Who is it?

I'll tell you if she gets into Sand Box.

The hackathon pitching presentations
will begin shortly.

-Already? Let's go.
-All participants

-Yes, let's go.
-and judges,

please come to the main auditorium.

Ms. Yoon, go ahead. I'll meet you there.

Okay.

How long has it been?

Well over ten years, right?

Right.

In-jae is here, too.

Yes.

Dal-mi is also here.

Right.

What a twist of fate.

You must resent me a lot.

Of course.

I don't even want to see you.

What mother
would be fond of a daughter-in-law

who abandoned her son?

I'm sorry.

How was Dal-mi

while growing up?

It must've been hard for her.

Yes, indeed.

Dal-mi got into a good university,
so I sold my corn dog shop

to pay her tuition fees.

As soon as I did that,

she dropped out of school
and picked up all sorts of part-time jobs

to buy me a truck
so I could sell my corn dogs.

Once,

she broke her leg

while working at a grocery store.

That really upset me,

so…

I said this to her.

You know,

you should've left with your mom.

Then you wouldn't be
going through this right now.

It would've been
only sunshine and rainbows.

Grandma, Dad told me

that deserts would cover the entire world
if it was sunny every day.

We need rain and snow

for plants and delicious fruits
like this tangerine to grow.

She's a wonderful young lady now.

I'm incredibly proud
that she's my grandkid.

Don't worry about her.

I didn't make this for you,

but you can have it.

You…

used to like
the spicy bellflower root salad I make.

Thank you, Mother.

Oh, boy.

Good Boy, you're here too?

-Let's sit over there.
-Gosh.

Oh, dear.

You should buy new shoes. What is this?

-What? They look as good as new.
-Jeez.

Are you blind? You call this new?

Why didn't you contact me?

I could've helped you
with Dal-mi's tuition fees.

No, actually…

You shouldn't have given me
that 70 million won.

Goodness, you're at it again.

Why would I keep your money?

Stop talking nonsense. I'm leaving.

Do you have regrets?

-"Regrets"?
-I mean…

Dal-mi could've
gone to college instead of me.

You could've kept your shop, too.

"I shouldn't have helped him."

You must've regretted it.

I never regretted it.

But I wish things could've been different.

I always wished I had met you sooner.

Then,

we could've played cards on the holidays,

and I could've made gimbap
for your school trips.

If anyone had bullied you,

I would've met their parents,

yelled at them to teach their kids better,
and fought for you.

I know I can't replace your parents,

but I could've at least been
a nosy old lady who lives next door.

That makes me a bit sad.

Darn it. Why would that make you sad?

-Try these gummies. They're good.
-Dong-cheon.

Yes?

-Take off that T-shirt.
-I'm not wearing anything inside.

-Just take it off.
-No, this is very inappropriate.

No, gosh. My goodness.

Oh my goodness.

-What's he doing?
-Gosh.

And come to the center of the stage.

Then the branches will spread out
with her in the middle…

Nice. That's a great idea.

Then will this image…

be displayed as well?

-That's right. With the labels.
-What?

-They'll be right here.
-Underneath.

-Yes.
-Can we lower them?

-Like this?
-Yes.

Then we'll display this image at the end.

-Yes, that will work.
-I like it. Let's do it.

What is it?

We went around and saw that

many CEOs aren't actually presenting.

And?

You should pitch our idea
instead of Dal-mi.

Why?

You saw. She doesn't even know
what a parameter means.

Our future depends on this,
so we can't count on her.

She didn't even go to college.
How's she going to explain AI?

Hey, people used to say
the same thing about us. Did you forget?

Of course not.
I remember like it was yesterday.

And you're saying this?

Looking down on someone
when you know what it feels like?

We're saying it because we know! We're
losers! So if our CEO is a loser too,

all these stuck-up pricks
will think we're a big joke.

Stop it.

Hey,

we're finished if we don't get in.

Will you move back into that moldy room?
I refuse!

Fine, then I'll present.

If you do, you'll really be screwed.

-Then what? Is Seo Dal-mi our savior?
-Well, I can't guarantee that either.

-Then why--
-However,

I can guarantee that you guys will fail.

Have you, self-proclaimed AI experts,
successfully pitched your idea

and secured funding even once
in the past two years?

Are you sure
you'll magically succeed today?

If you're that desperate, you should

at least try a different answer.
I mean, that's common sense.

But what if she's also the wrong answer?
Then we're screwed.

Then I'll invest personally.

What?

That gives you a plan B
even if you fail this.

Happy now?

That's better, I guess.

But why would you do that?

It's time. Let's go back inside.

Come on, guys.

Hello, I'm Yoon Seon-hak.

Finally,
Sand Box's intense 50-hour hackathon

is complete.

All right. Now, it's time for you

to pitch your creative business ideas
to your potential investors.

Let's meet the first team.

Hello. We've come up with a service
that analyzes kids' interests

and finds the best academy for them.

We are Savvy Mom.

JUDGES

SAVVY MOM

My Angel Eyes connects
the visually impaired

with volunteers and provides them
with real-time support.

Our designer, whose sibling

is visually impaired,
came up with the idea.

You're never sure how much money to give
as condolences, right?

Our service, How Much,

analyzes your cell phone usage

and suggests an ideal amount
based on your relationship to that person.

A new numbering system

for vehicle license plates
will soon be phased in.

To prepare for this,
we developed a recognition system for…

In order to make sure…

-What the…
-What is happening?

-Oh, no!
-That's bad.

-You guys are…
-They're screwed.

-Oh, no.
-I feel bad for them.

-They worked hard, but that's not enough.
-This is bad.

Working hard isn't enough.
You have to do a good job.

Thank you.

I'll revise this a little. Is that okay?

-Yes.
-Let's see.

Keep the intro short but impactful.

When you want to emphasize something,
speak slowly.

Keep this short.

Next up is team no. 17, Samsan Tech.

-You'll need time to…
-CEO Seo Dal-mi.

She's super nervous.

I can't see this. I'm covering my eyes.

JUDGES

Nice to meet you all.

I'm Seo Dal-mi, CEO of Samsan Tech,

a company that strives
to innovate the world through AI.

Let me ask you a question first.

Would identical twins
have the exact same handwriting?

Well, I'm thinking
it's probably different.

Am I wrong?
Do they have the same handwriting?

The correct answer is…

No, they're different.

A research institute in the US discovered

that even identical twins
can't have the same handwriting.

Handwriting is often referred to
as the brain's fingerprint

because every handwriting is different.

Therefore, many organizations
such as banks, the Prosecution Service,

the National Forensic Service,

and the National Tax Service
use it for identity verification purposes.

Hey, she's actually doing better
than I expected.

I know! She's better than anyone
who has presented so far.

However, things like your signatures
can be forged quite easily.

The rate of such forgery is eight percent,

but there certainly aren't enough
forgery detection specialists.

There are only 20 specialists
registered with the court.

I see!

They'll win at this rate.

What if we use AI to fill that shortage?

If it learns countless types
of authentic handwriting

and also forged ones
through machine learning,

we may be able to identify some patterns.

We, at Samsan Tech,
managed to find the answers

to these questions
during this three-day hackathon.

Let's look at the screen.

I'm sure it's great.

You bragged about it
in your business plan.

But what's the use?
You have nothing to entice investors.

BECAUSE, GRADUALLY

This is so cool.

My gosh.

What is your business model?

And how will you generate consistent
profit? You don't have a clear picture.

It analyzed the characteristics
of each signature

and handwriting
in Jeonghan Bank's 10,000 test sets

and determined its authenticity.

The accuracy reached 99.8 percent.

Yes! Applause! Give her a big hand!

If I were Yong-san or Chul-san,

I'd ask you to compensate me
for the past two years of my life.

That's right, 99.8 percent.

For the past three days,
I watched our team reach this number

and couldn't catch a wink of sleep.

Handwriting is only the start.

The potential applications
for this technology are endless.

Security, medical diagnosis,
smart factories, and self-driving cars.

Samsan Tech will enable
all of these things,

and I am so elated to be
a part of their journey.

Me, too!

We hope that this exciting journey of ours
begins at Sand Box.

Thank you.

She's our CEO!

-You're awesome!
-You rock!

-Dude, we did it.
-We did it!

Well, that wasn't bad.

Hey!

Dal-mi.

How was it? Did I make any mistakes?

-Could you tell that I was nervous?
-No, you were great.

No one could've done as well as you did.

-Really?
-Yes.

Gosh, thank god.

I was so nervous thinking
that I might ruin everything.

You did great.

Let's go.

Hello. I'm Won In-jae,

CEO of Injae Company.

We also used
Jeonghan Bank's handwriting data

but came up
with a different kind of service.

Ours is also based on AI technology,

but I'd say our approach
is a little more creative.

Jeez, that's rude.

What? Is she trying to say
that ours isn't creative enough?

Did you know that they were working
on a font technology?

Yes.

Those free fonts
you can download easily on the web.

It's no problem to use them
for personal use,

but if you design a flyer with those fonts

or upload a video on YouTube using them…

She's nervous.

Sorry about that.

It's copyright infringement.

It sounds petty, but it's only rightful.

To design one new font,

dozens of designers must work on it
for months.

One new design
requires 11,172 different letters.

Designing all of them one by one
can cost anywhere from 100 million

to one billion won. It's a huge project.

-That's really expensive.
-Hey.

If I told you that we could create
a new unique handwriting font

with only 256 letters, what would you say?

It's hard to believe, isn't it?

But we, at Injae Company,
put together a learning data set using OCR

and has managed to pull off
what no one thought was possible.

-Wow, that is amazing--
-Hey, don't.

This is a collection of new fonts
we created in the past three days

using 100 handwriting samples
from the bank's set.

If we were to create these fonts
in the old way,

it'd take at least three years.

And of course, it'd cost a lot of money.

However, Injae Company
created these 100 fonts

in less than 40 hours.

-Wow.
-My gosh.

Now, you can create your own unique font

using 256 handwritten letters

-and--
-Hold on.

I have an interesting question.

Hey, isn't that Chairman Won Du-jeong?

You're right.
What's Won In-jae's father doing here?

I don't like this.

Sure, go ahead.

The team that presented just before this.
Where are they sitting?

Oh, there you are.

You said Samsan Tech created an algorithm
that uses AI technology

to detect handwriting forgery.

Correct.

And your technology allows us to create
a new font using existing handwriting.

Right.

Then what will happen
if we put the two together?

Am I the only one who's curious?

What will happen if we put
a font created by Injae Company

through Samsan Tech's algorithm?

Will it say it was forged?

Yes, of course.

Then let's see
if it can really detect it or not.

This is a fight between
a spear and a shield, isn't it?

JUDGES

Please detect it.

Please, please…

Injae Company's technology
disabled Samsan Tech's algorithm.

JUDGES

All right. It looks like
we've narrowed down some candidates

for our 12th residency program.

But the last team is the problem.

They all got the same score,
so I'm not sure which one to pick.

I haven't scored them yet.

-Alex.
-Alex?

Aren't you Korean? What's with that name?

He's from 2STO in the US.

It's Sand Box's biggest strategic partner.

Oh, 2STO!

I met someone high up in the company.

What was his title?

Well, 2STO isn't
a hierarchical organization.

Right, that's what he said.

-Have you decided, Alex?
-Yes.

I'm sorry, guys.

I ruined everything.

What are you talking about?

We did our very best. We gave our all.

That's right! It's okay.
We have someone to fall back on, you know.

Mr. Han.

We'll actually let him invest?

Well, why not?

What we should be worried about
is him backing out.

I guess this is it, then.

Aren't you guys leaving?

The results aren't out yet.

Don't tell me
that you're expecting to get in.

Well, not really.

But just in case. What if they call
our names but we aren't there?

We don't want that to happen.

We really don't see eye to eye.

I hate people who don't know their place.

Why did you join our team
if you hate us that much?

To upset us?

I wonder, too. I must've been out
of my mind. That punk talked me into it.

Right, how did Ms. Seo persuade you?

She kept going on about
how the team absolutely needs me.

So I asked her why, and she said this.

Why me? Tell me your reason.
I'll make my decision after I hear it.

Okay.

I don't have a college degree.

I'm underqualified.

Luck made me a CEO.

What? Do you want to persuade me or not?

There's an amazingly talented developer
on my team.

He turned down an offer
from someone with stellar credentials

-and chose me.
-Is he crazy?

I bet he's regretting it now.

No. Not yet.

You don't regret your choice
the moment you make it.

It happens after.

You see, I've never regretted
any of my choices.

I did my best so I wouldn't.

So I'm confident that
I can make him never regret his choice.

This is nothing. I can get down
on my knees a thousand times more.

I can and will do anything.

She seemed so desperate,

and I wanted to meet
this "amazingly talented developer."

But he's nothing special.

Maybe Dal-mi is regretting her choice now.

Where is Dal-mi?

I saw her going that way earlier.

Nam Do-san.

Hey, did you find Dal-mi?

What?

Dal-mi got into a good university,
so I sold my corn dog shop

to pay her tuition fees.

As soon as I did that,

she dropped out of school
and picked up all sorts of part-time jobs

to buy me a truck
so I could sell my corn dogs.

Dal-mi could've
gone to college instead of me.

You could've kept your shop, too.

Oh, you're here.

I didn't see you.
I just wanted to sit down.

My, what a coincidence.

I should go.

Mr. Han, wait.

I'm sorry. I'm busy at the moment.

Thank you.

You did so much to help us.

I'm sorry the result wasn't good.

You don't need to thank me.
And don't be sorry. I'll be going now.

I have many questions for you.

I was waiting
so I could ask you those questions.

I understand why Do-san lied to me.

We met again after 15 years,

so he wanted to impress me.
I felt the same way.

I'm grateful he also felt that way,
and I get it.

Oh, I see.

But with you, I don't get it.

I keep racking my brain
but don't understand why you lied.

Why did you do that?

Why did you go to great lengths to
help us even if it meant you had to lie?

Well, that's…

Ms. Seo, I'm--

Dal-mi! Dal-mi.

-Dal-mi.
-Hey, Do-san.

We…

got in.

What?

-For real?
-Yes, for real.

Look. That screen over there.

"Samsan Tech." See that?

You still don't believe it?

12TH SAND BOX RESIDENCY RECIPIENTS
INJAE COMPANY, SAMSAN TECH

Subtitle translation by: Liya Choi

THE 15TH MATHEMATICAL OLYMPIAD
GOLD MEDAL NAM DO-SAN

He won a gold medal
in the Mathematical Olympiad?

Yes, he set a record
for being the youngest winner.

I see.

I looked up this company.

It's the seventh most valuable company
in the world.

What?

This is a once-in-a-lifetime opportunity
for Do-san.

Where did this punk go?

Behave yourself. Don't make any blunders.

Well, let's only showcase
Do-san's strengths to him.

-Only his strengths.
-Okay, nothing else.

GOLD MEDAL NAM DO-SAN

Do-san is a fool.

He's never been greedy in his life.

He was born that way.

Hey, do you know

why we don't have his gold medal here?

-You know?
-I don't know.

-No, never.
-That's very impressive.

Why the heck are you crying?

You lost to a kid. Aren't you embarrassed?

You can have this.

I don't need it.

I'd understand if it was anything else,

but that fool gave away his gold medal.

He was so smart

that he skipped high school
and went straight to college.

But even there…

Hey, you're in college.

That 13-year-old boy outdid you.

My goodness.

He intentionally answered all the
questions wrong for the older students.

Eventually, he ended up dropping out
and went back to middle school.

He prefers to lose

because he feels better that way.

That's why his nickname is Living Buddha.

"Living Buddha"?

He has no interest in materialistic things
or becoming famous.

Oh, there's one thing he's greedy for.

Food.

-Food?
-He's a glutton.

You know,

Do-san is as smart as
Steve Jobs or Bill Gates,

but he lacks ambition.
That's why he's in this mess now.

The moment he becomes ambitious,

it'll be game over.

-Have you decided, Alex?
-Yes.

Samsan Tech is my choice without a doubt.

Samsan Tech?

Why?

Well, I've thoroughly looked
over his algorithim,

and when you consider the short time
that was provided to him,

it's quite amazing actually.

Maybe it's just me, but…

I see something very special.

And I was the first one to recognize it,

so, I'll be the one
who he takes the first step with.

We've been assigned our office.

I want Mr. Han to be Samsan Tech's mentor.

Ms. Seo, you frustrate me.

-I will be your reliable Sherpa.
-It hurts.

I'll do everything I can like your father
covered the ground with sand for you.

You two must've teamed up
to steal my shares.

And the biggest problem here is that
the CEO can't resolve the situation.

Ms. Seo, you're the problem.

Regarding why you helped us…

I'm thinking of telling Dal-mi
the truth today.
