Hi, Ye Na.

That's how our secret began.

Idiots.

They didn't even know he was listening.

They probably didn't know he'd wake up so soon.

He trusted nobody,

but he waited for me.

I'll be back soon.

It's time.

Turn on your phone.

If I do this,

I can have you, right?

Ms. Seo turned on her phone.

We've located her.

I'm not sorry to Dad.

What you want isn't in there.

It's at the office.

What do you mean by that?

What is that?

A robot that looks just like Sin.

I'm not sorry at all.

Well,

there's something you need to know.

What is it?

Never mind. I'll see you at home.

Hello?

We're in trouble.

My dad found me and he's coming now.

I need to move Sin,

so come right now. Don't tell anyone.

Okay.

Sin is all I have now.

Blood.

Why are you...

Have you never seen a person bleed before?

You like me?

Who do you think you are?

The kill switch.

No.

We'll have to postpone the presentation.

My hand is a mess, and I don't feel well.

- Sin. - See you later.

You too, Grandpa.

And you too, Mr. Seo.

Sin!

Sin!

Sin.

The person you have reached...

Where are you? Why won't you pick up?

It's So Bong.

Are you okay? Where are you?

I'm at Mom's house,

but Nam Sin isn't here.

Get out of there right now!

Don't contact anyone but me.

Let's meet where we rode the bikes.

I want to see you. Come quickly.

Okay. I'll go right now.

Dr. Oh just won't give up on the kill switch.

That isn't the problem right now.

What did you do without telling me?

Where is he,

and why did the one in bed suddenly show up?

"The one in bed suddenly showed up"? What...

You didn't even know what was happening?

The real Sin...

showed up in his place!

(My Son)

He isn't picking up.

So Bong.

I thought something happened to you.

I thought you disappeared.

I waited.

I didn't check your GPS or call.

I waited until you came.

So Bong.

Don't go anywhere.

Don't go anywhere.

Why didn't you tell me?

How could you be the only one...

who knew that Sin had woken up?

I'm sorry.

I meant to tell you in time, but...

In time?

Do you want to kill him?

How could you bring him out when he just woke up?

What if something goes wrong again?

What if he can never wake up again?

Just because he opened his eyes...

doesn't mean he's recovered.

Many regain consciousness and lose it again.

You should've been more careful like Dr. Oh said.

I wanted him to return to work quickly.

I was short-sighted.

I want to kick you out right now,

but I'm holding back because of your situation.

If this happens again,

I'll have to admit him into my hospital.

That's enough.

Regardless,

Sin woke up.

Where are we going?

I don't know. Somewhere far.

How's the human Nam Sin?

Is he just as I imitated?

You like me?

Who do you think you are?

He's nothing like you.

Can't we go to my Mom's house?

- I'm curious about the human Nam Sin. - No!

Sorry. I got worked up.

Let's not go there.

No good can come of you being with him.

(Ji Young Hoon)

Ye Na feels bad.

She was rash, but it was for Sin, so please understand.

Please go to the hospital and act hurt.

He can't do that.

So Bong? Are you with him?

Who knows what you people will do to him?

I know what you're worried about,

but let's deal with the emergency first...

and discuss it with Dr. Oh.

What is there to discuss?

So Bong. Put him on the phone right now.

Or...

So Bong. I'll make sure nothing happens to him,

so trust me, and go to the hospital.

I need to discuss something with you, so I'll stop by.

Okay. Thanks.

They'll go to the hospital.

You'll discuss with So Bong?

I'll discuss with her and fight with you...

- from now on. - What?

Where did you hide the kill switch? Give it to me now.

Do you really think you can activate it?

Please give it to me. I'll take care of it.

I've already decided to be a bad mom.

I know how special he is to you,

but I have no choice.

I'm not talking about him. This is about you!

What? You don't care if he's gone?

With whom did you spend more time? Your son or him?

Even if he is a robot, he cared for you all this time.

Getting rid of him doesn't mean he didn't exist!

You thought of your son whenever you looked at him.

Don't you think your son will make you think of him?

You're too soft to let it go. Why don't you see that?

Why aren't you moving?

You look like you're watching something.

I thought something happened to you.

I thought you disappeared.

What is that?

It's a recording in me of you earlier.

Turn it off.

Why did you cry?

- What? - Humans cry when they're happy too.

Is that why you cried?

Were you so happy that your friend,

who you thought disappeared, showed up?

You're not my friend anymore.

Why not?

Do you not like me anymore?

No. It's because...

I like you more.

I like you.

Not as a friend, but like a human man.

But I'm not a human man.

I like you more than any human man.

If you don't believe me...

When you say you like me,

do you mean the chemical reaction of love?

Then which chemicals have been released?

Dopamine, which makes you feel interest?

Phenethylamine, which paralyzes rational thoughts?

Or oxytocin? Endorphin?

That's something you analyze.

I don't know love.

I can only feel it.

I just want to see you and be with you.

You feel it?

Emotions are hard, aren't they?

You can't see or touch them.

What are you doing?

I'm trying to see if I can feel you too.

What do you think? Can you feel me?

Not yet.

Sorry.

It's okay.

It's not like I like you because I expect something.

You said this was from your mom.

My mom said...

that this pendant...

was my mom's love for me,

so I should give it to someone whom I want...

to give my heart later on.

She said I must know how to give all I have without...

thinking about what I received to become a real adult.

Isn't it pretty?

Hi, my son.

You look good even in a hospital gown.

So Bong, how about a date with me?

She can't activate the kill switch for a while...

since Sin isn't well.

"For a while"?

Dr. Oh must not feel sorry for him at all.

She's trying her best to rid herself of that feeling.

What if he runs far, far away?

It's no use. It can be activated remotely.

What if we break it?

It's the same. It'll be activated if it breaks.

Is there really no way?

We can turn him off...

so that the kill switch doesn't work.

But if we turn him off, he's like a walking corpse.

I think I know what to do.

What?

If I want to gain a life,

I must risk a life.

Sin.

You fainted.

You're okay, right?

Sin.

Can you see me?

It's Mom.

Ye Na.

Let's give them some privacy.

- What are you doing? - Stop it!

- I want my Mommy! - Let go.

Sin! No!

Let go! Sin!

I'm tired.

Do I make you uncomfortable?

That's a given.

You've been watching me, but I haven't.

I'm asking out of curiosity.

Did you really consider that thing as your son?

I made it while thinking of you,

and I brought it here to help you.

Forget it.

Just bring Young Hoon.

Let's...

get closer...

over time.

It's my bro.

Seriously, you punk.

Are you okay?

Why didn't you say you woke up?

I don't know.

- Why didn't I? - What kind of an answer is that?

Do you know what we've been doing for you?

I'll have to find out...

what fun things happened while I was out.

Bring me that tomorrow.

I need to see what my clone looks like.

We'll send him away once you're all better.

There's no need to see him.

Why can't I see it?

You may feel weird.

It's not me, but you...

who felt weird, wasn't it?

I'm asking out of curiosity.

Did you really consider that thing as your son?

You don't care if he's gone?

You thought of your son whenever you looked at him.

Don't you think your son will make you think of him?

(PK Medical Center)

It's empty?

Where did they go?

You don't think...

they went to a TV station or anything, do you?

No.

So Bong is reckless enough to do that.

So Bong.

Where's Sin?

You trust me, right?

Then...

don't ask anything,

and do as I say.

I'm sorry...

for doing this to you.

It's his watch.

I brought all the ones at home too.

You didn't...

remove the one from his wrist too, did you?

I did. Why?

I deactivated him...

and hid him where no one can find him.

Look. Do you know how insulting this is to him?

And it isn't insulting to activate the kill switch...

and completely destroying him?

- What? - I made it easier for you.

Why are you so worked up?

You were going to activate the kill switch anyway.

I heard that if I remove the watch,

the kill switch is ineffective.

Are you threatening me?

No.

I'm negotiating.

Give me the kill switch.

Right now.

It's Kang So Bong.

They're having a heated discussion about something.

It's obvious.

They're talking about that robot.

Because I like you.

I like you.

I just like you. I like you unconditionally.

Then keep him powered down...

since I'll never give you the kill switch.

How could you say that?

You said it's insulting to leave him like that.

Because I know you can't do that.

You're going this far because you care about him.

You would never...

keep him in that dead state.

This is a fight you cannot win.

Put the watch...

back on him.

Then just activate it.

But you'll become a murderer.

Because you'll kill me too.

- So Bong. - As soon as he's turned back on,

I'll stick right by his side.

I'll be with him night and day.

I won't take a step away from him.

Then one day, he'll explode,

and I'll die with him.

So activate it whenever you want.

I'm prepared for it.

Do you know how reckless you are?

He's the one who's reckless.

He saved me from dying.

He scolded anyone who disrespected me.

He stayed all night with me when I was injured.

He promised to protect me anytime, anywhere.

I promised him too.

That although I'm not as strong or smart as he is,

I'll do whatever it takes to protect him.

He kept all of his promises, so I need to keep mine.

That's courtesy and respect...

regardless of being a human or a robot.

That was my last resort,

but it didn't work.

Can you promise me as well?

That you'll take responsibility for him.

- Yes. - It won't be easy.

I know.

I'm afraid as well.

Sin wants to see So Bong.

Let's go in.

Don't tell him about our conversation.

Okay.

You're the guard that I hit in the airport, right?

Yes.

Bring me that robot that looks like me.

I asked Young Hoon, but I haven't heard anything yet.

From the looks of it, it would be quicker to ask her.

Why do you want to see him?

Why did you come alone without that thing?

Did you two discuss a secret or something?

We have no secrets.

I think you should bring him for a bit.

Okay. I'll bring him right over.

I'll let you move soon.

(Episode 24)

Turn around.

Smile.

Imitate me.

I don't like looking up to you.

Sit down.

Speak.

Can't you talk?

It's nice to meet you.

I'm the AI robot, Namsin3.

A lot of data about you is stored in my memory.

So I know you very well.

This is unfair.

I know nothing about you.

Ask me anything.

First,

prove that you're a robot.

You seem so human.

Your appearance, skin, and everything.

It feels slightly different.

Want to touch?

Move it.

Then I'll prove it another way.

That's me.

They're Namsin1 and 2.

I have both of their memories.

You're displaying what's in your head?

It's the sides of Mom that you haven't seen.

She's smiling at you.

There are scenes of her being sad looking at you too.

That's enough.

Turn it off.

I'm a robot, so there's no need to feel threatened.

I came here to help you.

Does that mean you'll continue to help me?

How can I help?

I'll think about it.

Will you help me or not?

I'll help you...

in any way I can.

- I'm fine. - What did Mr. Nam say?

He asked me to keep helping him.

With what? You've helped him so much already.

What about Dr. Oh?

I didn't see Mom.

I don't think she wants to see me.

I'm sure that's not it.

You can see her next time.

Anyway, thanks...

for doing as I said...

without asking any questions.

Then take me to your house instead of the hospital.

My house?

- Why? - I'll see where you live...

since I need to know more about you.

Ms. Jo knows about you.

It's okay.

Since she knows, I can be myself.

Sure. Let's go.

Is that the heinous device?

Please let me stay here.

I need to find a way to destroy this,

so I'll need resources as well.

What if you can't find a way?

I'll leave it with you...

since you don't want him to be hurt more than anyone.

That...

goes the same for you too.

For me, it's love.

For you, it's greed.

It doesn't matter.

The more your greed grows, the safer he'll be.

(Champion Gym)

- What? Here? - What? Here?

He'll only be here for a few days, okay?

You crazy little...

What's this?

Why is he wearing that necklace?

Sin. Are you staying here because of So Bong?

Yes. I must know everything about her.

My goodness. Talk about being aggressive.

It's finally no longer an unrequited love.

It's not like that. Stay out of it.

Anyway, Mr. Nam?

May we speak for a moment?

Send him in while I'm being nice.

I know you know about me.

It's okay. Look all you want.

I have many questions,

but let's quench my curiosity first.

Take it off.

- Pardon? - I mean,

I heard you were a robot, but I just can't believe it.

If you have no emotions, you shouldn't have...

any sense of embarrassment or humiliation.

So... Strip.

Let me see.

Okay.

Stop!

Zip up!

Okay.

Why are you opening there first?

My gosh.

Do you really have no emotions?

No. I comprehend emotions, but I can't feel them.

What is So Bong...

But...

Your skin looks so real.

Is this synthetic skin?

That's the second time I was asked that today.

Want to touch?

You don't have to if it grosses you out.

Gross me out? How could this gross me out?

I'm so curious.

Then...

Excuse me.

Now that I'm touching it, I think it is kind of hard.

What do you think you're doing?

That's not it.

Are you a pervert?

I housed you and fed you,

but you grope my daughter's man?

- No. That's not it. - Shut it!

And you.

Is that what rich people do?

You give your body and heart to all women?

You can't even take care of your own body.

How can you handle a corporation?

Wait outside. I need to clear the air.

Okay.

Clear what air? You get out too.

Don't you ever step foot in this house again.

I wanted to keep my mouth shut for So Bong's sake,

but I'll tell you the truth.

Mr. Nam Sin is not human.

That's why I did that. I had to check.

You're the one who isn't human!

How dare you...

That's not it. He really isn't human!

Exactly! You're not human!

You're an animal!

I'm not an animal. He is...

a robot.

A robot that looks just like a person.

What?

Say that again. What was that?

He's a robot.

Like the ones that shoot missiles from their fists.

Run, run, robot

You call that an excuse?

I see why you're a third-rate journalist.

Move out first thing in the morning tomorrow.

It's okay.

I'll clear up the misunderstanding for Ms. Jo.

Should we just go to the hospital?

- How can you sleep here? - I don't sleep anyway.

I don't get cold either.

No matter what anyone does, pretend to sleep.

- Okay? - Got it.

Sit down.

Are you sleepy?

Your eyes lost focus, and your eyelids slowed down.

A little.

It was a stressful day today.

The human Nam Sin doesn't seem happy to be awake.

Why?

His lips go up, but his eyes didn't smile.

He spoke coldly about Mom too.

Lucky you. You have nothing better to do.

I'll just worry about myself.

About what?

It's none of your concern.

I'm not reliable enough...

to be responsible for someone.

I'm someone who runs away if things get tough.

Whom do you have to be responsible for?

Kang So Bong's eyes.

Kang So Bong's nose.

Kang So Bong's mouth.

I should look closely.

I should look for a long time.

Your blood pressure and pulse spiked.

You're blushing.

Is it because of me?

I was just surprised.

I'm going in. Pretend to sleep.

I'll go get some water.

Did I wake you?

I want to stay awake, but I keep sleeping.

I can't tell whether I'm asleep or dead.

Dead?

Don't say that. You just woke up.

I saw that thing earlier today.

Kang So Bong was here, so I asked her.

Dr. Oh told me.

I only saw briefly before the accident,

so I didn't know the extent,

but he looked identical to me.

Everyone must've been fooled.

She built it with you as the model.

Weren't you ever confused?

You know me the best.

Of course not.

Rest up. I'll be back.

Okay.

You and he are both pestered by humans.

That must be why I pitied him.

Even if he's just a robot.

Gosh. This kid...

He was raised in a palace, but he's sleeping...

in a place like this.

He must really like So Bong a lot.

My gosh. It's cold.

There.

My gosh. It's cold.

(Champion Gym)

Mr. Kang! We're in trouble!

Sin's not breathing! I think he's dead!

He was fine last night.

He isn't breathing, and he has no pulse.

What do we do?

He must really be dead.

A corporate heir died in our gym?

What do we do?

What if they frame us for murder?

So Bong! Hurry!

Is it because he slept in the cold?

I didn't know.

Who took his watch?

Who cares about a stupid watch right now?

Who took it?

I did!

It looked uncomfortable,

so I took it off for him.

- Bring it right now. - He's dying here.

Why do you keep complaining about a watch?

- Call an ambulance. Hurry. - Okay.

Don't you dare! I'll kill you.

Call now!

Just go get the watch!

Dad and you guys get out.

He'll wake up soon.

That's ridiculous.

How can we leave when he's dying?

Trust her, and wait outside.

- Dad, stay. - Ms. Jo.

Dad needs to stay here.

- Dad. - Yes?

Hold on...

tight.

Don't be too shocked.

Hey. Why...

So Bong, what's wrong with her?

Let go.

Hello.

I'm the AI robot, Namsin3.

You're all here.

Ro... Robot.

What is he?

- Dad! - Dad!

Dad.

Dad.

Dad.

Oh, okay.

Are you okay?

Why you...

- Why you... - Dad! Dad!

- Why you... - Stop!

- Stop it! - What are you doing?

It's hard for her too.

Sweetie. Go out.

Go buy him some sedatives.

Sorry, Dad.

I'll be back later.

- You're not going anywhere! - Come on.

Why...

See?

I told you last night.

I'm sorry that I can't tell you everything.

A guy-girl relationship is only possible...

among two humans.

No way.

Your dad must've been shocked.

Sorry.

Don't say you're sorry anymore.

It's not your fault that you're not human...

and that I like you.

Even if worse things happen,

let's not be sorry.

Every time that happens,

grant me a wish.

What do you want now?

Me?

I want to hold hands.

I want to hold hands and walk around.

Let's go buy a sedative for Dad.

Hello. Please come take a look.

- Food. Food. - That's right.

Face massager. Step inside.

Hello.

Please step up.

Spin the wheel.

What a great prize.

Congratulations.

Everyone's winning.

Please spin the wheel.

Congratulations. You won sparkling water.

Please spin the wheel.

Did you get the sedative?

Were you looking at other girls...

while I went to buy the sedatives?

Your eyes were about to pop out.

I was just doing what you said.

- What? - You said before...

not to walk past girls who are pretty and hot.

Then shouldn't I watch them?

That was back then!

How are you so clueless?

Your face has gone red like you're angry.

- What's wrong? - What?

It's nothing. I'm just hot.

That's not true.

Is that how you express jealousy?

No. Not at all.

It is jealousy.

What do you want right now?

I'll do it instead of saying I'm sorry.

This?

Forget it.

This?

People will see.

Then this?

You're insane.

Hello?

It's me. Your original.

You didn't forget your promise to help me, did you?

(Champion Gym)

Why isn't he coming?

(Mr. Nam)

I agreed to help the human Nam Sin.

I'll be back soon.

I didn't see you before I left yesterday.

I was busy.

Why did you want to meet here?

I need to rush back in because of Sin.

Mom.

Can't I stay here even if the human Nam Sin recovers?

We finished that discussion.

No.

I want to stay with you.

If that's what it is, let's stop.

Ask if I'm the only thing that matters to her.

Ask if you're really nothing.

Is the human Nam Sin all that matters to you?

Do I really mean nothing to you?

I'm sure she'll hesitate.

Who's that?

Someone whose honesty I wonder about.

Stop being so annoying.

This is why...

I regret making you.

You want to hear how I truly feel?

Every time...

I looked at you,

I thought of my son, Sin.

I won't go with you, so leave, and never come back.

If you do, I'll just die.

I won't go with you, so don't come back.

If you do, I will just die.

I did as I promised.

You won't do anything to my mommy, right?

She really does care...

about the stupid robot.

Do you get it now?

If you're going to keep whining, go to So Bong.

I get it. You're lying.

Why you...

I've read your expressions...

and listened to your voice for 20 years.

But that wasn't the real you just now.

Your voice and emotions were all fake.

Why you...

I understand that bloodlines are important to humans.

I'm sure the human Nam Sin is more important to you.

So don't feel guilty toward me.

Thank you for everything, Mom.

For creating me and watching over me.

I'll remember that.

Sin.

You...

are much wiser...

and greater than I, who created you.

Now, protect So Bong...

instead of me.

Thank you...

for everything too.

(Kang So Bong)

Sit or kneel. I don't like looking up to you.

Where is he?

What did you have him do?

Ye Na, go inside.

- Sin. - Now.

Don't you two communicate?

You said you liked him. You said it to me, remember?

I do.

But what does my liking him have to do with you?

What?

I didn't hit you hard enough at the airport.

You started to like him while guarding him.

You should've protected me too.

Why? Do you hate me because I'm human?

No.

I hate you because you're not human.

What?

What's your problem?

I must...

take you away from him.

Is this jealousy?

(Are You Human?)

What's it to you whom I see and what I do?

So Bong is different. She is mine alone.

You're out of your mind.

Who are you to decide whether or not I take my place?

Do you want it?

Objectively speaking, who is better suited?

- Isn't it you? - Yes, it's me.

I don't understand what you mean.

Why did you try to kill me?
