Seon-a!

Seon-a, please wake up!

Seon-a!

OPERATING ROOM

Where's Seon-a?

Why were you at school that night?

I was looking for Seon-a.

You were looking for her?

She called me

on her way to school.

So late at night?

I don't know.

I know for a fact...

Seon-a...

didn't try to kill herself.

Is the Korean teacher still not here?

Someone should try calling him.

What a day to be late.

I'm trying to reach him, but he isn't answering.

How could we let something like this happen at our school?

She could've killed herself at home.

Why did she do it here, at our school?

Excuse me.

I think you're crossing a line.

And for your information, she's not dead yet.

You're in no position to lecture.

You're just as responsible.

Yes, I'm well aware of that.

We're all responsible for what happened.

What I don't get is why you're blaming her.

What the hell are you talking about?

- That's what you're doing. - I can't stand this!

I said what I said.

Then let's talk in my office!

- Calm down. - Do you hear me?

- Unbelievable. - That's enough.

You have no right to get heated.

- Settle down. - It's not that.

Are you okay?

I'm stressed out enough as it is.

You're making things much worse.

- Let me through. - Sorry about that.

Anyway, make sure this doesn't happen again

and not another word about it.

- God, you reek of cigarettes. - No, we smell great.

Your teeth are gonna turn yellow.

You should try it sometime.

Your teeth are so yellow. They look like corn.

What?

You guys are funny.

Join us for a smoke.

Hey.

Where's Hye-yeong?

What a fucking coincidence, right after Seon-a fell off the roof.

- Is school too boring without her? - Maybe.

It's all my fault. She's in my class.

No, don't say that.

The school violence committee almost met because of her.

Is the Korean teacher still not here?

That's weird. This never happens.

This is exhausting.

Does anyone have good news for a change?

It's always bullying, suicides...

- Hey, Mr. Kim. - Yes?

How are the wedding preps going?

Did you set a date?

We called it off.

THE APARTMENT

Come in. You can leave that here.

Are you hiding? A-yul.

Come say hi to your uncle.

Come on.

There you go.

A-yul.

Are you shy?

You didn't bring much luggage.

I'm only staying for a week.

I shipped the rest of my stuff.

Quitting your job and moving to Canada... It's so sudden.

My goodness.

Have a seat.

Okay.

This is your first time here, right? How do you like it?

It's great.

Did you move in last year?

What? No.

It's been over two years.

Time flies.

It's all thanks to Mr. Kim Byeong-cheol.

So he's my brother-in-law?

How so?

Does he mind me staying here?

Why would he? You're my little brother.

Besides, he's way too busy. He won't be around much.

Let me see.

There.

You're going to work until you leave, right?

Yeah.

One second.

Kang Seon-a.

Wake up and say something.

You have to look for proof.

For Seon-a's sake, right?

I know her. She's a real bitter bitch.

Suicide? That's ridiculous.

And Kim Hye-yeong, who bullied Seon-a every day,

skipped school the very next day.

Now that's suspicious.

Who are you?

I'm Lee Gyeong-jin from Class 5.

Assuming it wasn't a suicide but a murder,

the number one suspect is the person who was closest to the victim.

But Seon-a was a loner.

No, wait.

Recently, she had people she hung out with.

She's not dead.

- What? - Seon-a is still alive.

Right. Sorry.

That reminds me, you were friends with her.

Where did you get these glasses?

At a store.

When?

- Last year. - Why did you never wear them?

I wore contacts, but they hurt my eyes.

Excuse me.

Yes?

Do you happen to know who these glasses belong to?

I'm not sure.

Why do you ask?

They were on my desk.

They must be yours, then.

Try them on. I bet they'd look good on you.

Sure.

It's all my fault.

I should have taken better care of her.

I was her homeroom teacher and I didn't notice a thing.

You think this is a suicide attempt?

- Sorry? - It hasn't...

been ruled a suicide yet.

Anyway,

I'm willing to help if you need me.

Call me anytime.

Is the student who was bullying Seon-a here today?

That student

has been reported missing.

Missing?

Yes.

What about this student?

I found this in Seon-a's bag.

It looks like it was taken on the day of the accident.

Are you Lee Ji-won?

Yes.

I'll get straight to the point.

Were you in a relationship with Seon-a?

No.

If you weren't,

why were you together?

She wanted to meet up.

- And you always say yes? - Why not?

You know.

It was pretty interesting.

It was like the loner had become a different person.

I knew she always had a thing for me.

Did you notice anything strange while you were with her?

Well...

Not really.

What about at the café?

Can I be honest with you?

We talked and then we kissed.

I wanted a little more

but she didn't want to.

And then what?

Oh, I remember.

We took a picture

but then she started running off somewhere.

She said she lost something.

HAN JI-UK

OH DONG-SIK

SINU GREEN PARK (1)

SINU GREEN PARK (2)

- Cheers. - Right.

Cheers.

I'm sorry for showing up unannounced.

- Hey. - It's fine. Don't worry about it.

Jeong-u.

That's your name, right?

Yeah. No need to be so formal.

By the way,

you two

- don't look alike at all. - What?

He's so handsome.

Cheers.

Can I ask you something?

Go ahead.

I heard you're not getting married. What happened?

Honey, don't...

It's okay. Let him talk.

We'd been living together for a while

but shortly before the wedding,

I came home from work early and saw her in bed with my friend.

My God, Jeong-u.

You made the right call.

For that to happen before the wedding

is the best luck you could've had.

I really like this guy.

Come on, let me pour you one.

Thanks.

Pour me one too.

- You good? - Yeah.

Here you go.

What is it?

- Sorry about that. - No problem.

It's all work messages.

So many texts...

What subject did you say you teach?

I teach English.

I sometimes meet people from other countries because of work.

Jeong-u.

Do you know what people who visit Korea like the most?

Take a guess.

Go on.

It's been a while since you've talked to your sister, huh?

Yeah. I didn't take her calls often.

Well.

Stay in touch from now on.

You're the only family each other has since your parents passed.

That's right.

I'll keep in touch.

Hello.

Whoops.

Jeong-u, where are you going?

We live on the tenth floor.

Oh, right.

You can't hold your liquor very well, can you?

I'm telling you. It's not a suicide attempt.

You can't close this case.

What do you mean, Detective Han?

We heard what the doctor said.

No signs of violence.

Be honest with me.

Were you aware that your niece was being bullied?

It's possible this was a suicide attempt.

All the more reason to investigate. It might not be!

Ji-uk.

The higher-ups want to close the case.

The school's foundation is fed up.

A suicide is bad enough.

But a homicide? They'll throw a fit.

I know how you feel.

But let it go.

Will you?

What if it was your kid?

What the...

You just crossed the line.

You crossed it first.

What?

Hey. Ji-uk!

ENTER CODE

Holy shit.

This is impossible to bypass. They can't even do it in the US.

PHYSICS, LEE GYU-JIN

You're wearing the glasses. They really suit you.

Thanks.

The Korean teacher is still unavailable.

It seems so.

If you found out

that someone you knew was having an affair,

what would you do?

Well...

Is this something that happened for sure?

I'd let everyone know

and let all hell break loose.

Like a scene from a soap opera.

I see.

You were so shy at first.

Now you love him?

A-yul.

Hold Mom's hand too.

You're a clever one.

- Who's Oh Tae-seok? - What?

It was misdelivered.

It has the right address, though.

No, it belongs to Unit 401.

They sometimes put the wrong address. I'll take it to them.

No, take A-yul inside. I'll go.

Just drop it off at the security office.

Sure.

Want to try opening the door?

OH TAE-SEOK, UNIT 1002

Unit 401?

Hi, honey. I'm almost home.

The grocery bags are so heavy.

You said I could buy whatever I wanted.

There's another package.

No, it's not mine. It's yours.

Well...

I'm not sure.

RECIPIENT: OH TAE-SEOK

RECIPIENT: KWAK CHAE-RIN

Kwak Chae-rin.

A-yul, let's say hi to Grandma.

Okay.

Let's say hi.

- Where's Byeong-cheol? - What?

He's in Gumi.

He's not coming home today?

When he visits the factories in Gumi,

he spends two or three nights there.

How's married life?

It's good. Raising a kid like everyone else.

You should get a facial or something.

Byeong-cheol makes enough money.

You've changed a lot, lecturing me like this.

Mom should've seen this.

Jeong-u.

About your breakup...

It wasn't because your ex and her family didn't like the fact

that you didn't have parents, was it?

It wasn't that.

I told you. She was cheating on me.

It's good to have you with me on the day Mom passed away.

As for Dad...

You're not in touch with Dad's side of the family, are you?

Well...

Sometimes Uncle calls and...

Have you lost your mind?

Did you forget what it did to Mom after Dad cheated on her?

How can you talk to them?

I just...

You were too young to understand back then, but...

I was just going to marry Su-yeon.

We lived together for six years. I was going to let it slide.

She swore it was a mistake.

She was on her knees saying she was sorry.

But one day...

I could see Dad's face.

Dad probably said he was sorry at first too.

Is this how Mom must have felt?

The face of the girl I loved so much

kept reminding me of the person I despised the most.

I still love Su-yeon.

I miss her.

But I can't see her because of Dad.

That man is ruining my life from his grave.

- This is crazy. - What is this?

Is this for real?

Not a day goes by without some kind of uproar.

Unbelievable.

- I never would've thought... - It's him?

- The Korean teacher... - How is this possible?

Hey, come over here, quick.

It's Kim Hye-yeong and the Korean teacher.

- This is unreal. - Wow.

- Are you kidding? - You're lying.

- This is nuts! - Come on.

This is crazy.

Is this for real?

DO NOT CROSS, INVESTIGATION IN PROGRESS

I am Bang Seong-jin.

I teach Korean at Bangju High School.

For a while, I was

in an inappropriate relationship with a student.

I apologize to my family.

The humiliation and guilt that will befall me

when this is revealed

has led me to end my own life.

I am sincerely sorry for causing so much trouble.

Hey, don't touch that.

I have my gloves on.

SUICIDE NOTE

I AM BANG SEONG-JIN, A KOREAN TEACHER AT BANGJU HIGH...

What's the estimated time of death?

Well...

We'll need an autopsy to confirm that

but I heard it's been at least three days since he died.

It doesn't feel like it happened here.

What?

This car is parked in the middle of this lot

and no one sees it for three days?

The pictures were posted today.

He knew it was going to get out.

Someone's behind this.

Hey, Prez!

We're getting tteokbokki. Wanna come?

- Sure. - Really?

You never want to join.

You got a crush on me or something?

Or maybe it's Hyeon-heup you're interested in.

BANGJU HIGH SCHOOL

- Hey. Get in the car. - Who are you?

Do you know this guy?

He's my neighbor.

It's illegal to park here. Get in, quick.

Hey, mister.

Who are you to tell us what to do?

Mister?

Yeah, right. Are you trying to kidnap us?

That's a pretty bold attempt.

You're totally sick.

Hey, call the police. Come on.

You want the police? One second.

Hey, look. The police just showed up.

Get in. Quick.

You never came by. I thought we were friends.

I'm not suspecting you or anything.

You said it yourself.

She had no reason to kill herself.

Why do you think Seon-a went back to school in the dead of night?

Did you see

Seon-a's glasses?

Glasses?

Tell me the truth.

What do the glasses mean?

Does Seon-a also have something to do with them?

The glasses.

You have to find them.

Then I'll tell you.

Tell me what?

Taxi!

HOTEL

The key is inside.

Let's just start eating.

Are you done now?

Wait. What is this doing here?

Oh, my God!

What is this?

This is beautiful.

- This is embarrassing. - Come on.

Let's see.

Here you go.

Let's eat.

Hello?

Hi, Byeong-cheol. It's Jeong-u.

Hey.

Jeong-u, what's up?

Is this a bad time?

I'm in the middle of a meeting.

I can't really talk.

Where are you?

Right now?

I'm not in Seoul.

I'll call you when I can.

Byeong-cheol.

I can't get ahold of my sister.

Really?

In that case,

I'll try giving her a call.

Okay? I gotta go.

ROOM NO. 2407

Just a minute, okay, honey?

- Who is it? - Room service.

Hey!

Jeong-u.

Let go of me.

Let go.

What the hell do you think you're doing?

I'd like to ask you the same thing.

Well, I...

Jeong-u, I understand

how all this might look to you.

But you have to respect my privacy.

I mean...

This doesn't do your sister any good.

You're so shameless.

Shouldn't you be apologizing first?

You're right. Okay, I'm sorry.

I don't have the words to say how sorry I am.

Wait!

Okay.

I'll break it off today, right here.

I swear it.

Just give me a little more time.

I really mean it. I'm serious.

You will?

End it today.

Otherwise, who knows what I'll do.

Jeong-u.

Don't tell your sister.

When will we see each other again after you leave?

We only just got back in touch.

Canada's not that far.

I'll call you often.

You'd better.

Call me if anything comes up.

She's going to miss you when she wakes up.

Here, it's not much.

It's for your expenses.

- You didn't have to. - Go on.

Still no call from Byeong-cheol?

What?

He'll call when he can.

He must be busy.

Call me.

I will. You don't have to see me off.

The soap opera thing.

Did you take care of it?

Not really.

I don't think so. Maybe I did.

It's bad enough that things are chaotic here.

I'm sad to hear that you're leaving too.

Thanks for everything.

It was nothing.

Have they found Kim Hye-yeong?

No, not yet.

Who do you think posted the pictures?

Well...

There are plenty of people who'd do it.

There are rumors that the pictures were all over social media even before that.

"Chae-rin."

KWAK CHAE-RIN

GOING FOR A DRIVE IT'S BEEN SO LONG

YOU'RE THE BEST, HONEY I'M SO TOUCHED

Let's see. Here you go.

That bastard.

NO TRESPASSING

The number you have dialed is unavailable and has been transferred...

Hello. Can I help you?

We're trying to get into the complex.

Sorry, just a minute.

Sir. Excuse me, sir!

Oh, my God.

You need to stop!

Stop! I said, stop!

Oh, no!

Oh, my God!

What's wrong with that person?

Someone, call the police please.

Oh, no!

What's happening?

Are you okay?

- What's going on? - The person did it on purpose.

- You need to stop. - Come on.

Are you okay?

- Oh, my God. - What's happening?

Gyeong-mi.

Are you okay?

Open the door.

That scared me.

Are you okay?

I'll take care of this.

Take A-yul and--

Jeong-u.

Why did you do it?

What do you mean?

Why did you do it?

What are you talking about?

Why did you have to do that?

What the...

- You... - Honey!

Hey.

- Are you okay? - Honey...

This woman just crashed her car into mine out of nowhere, and...

It's all right.

I'm sorry.

Let me go, you thug.

- Oh, my. - Oh, my.

You're no better than an animal. You bastard!

Let me the fuck go!

Stop it!

Stop.

Stop it, Jeong-u.

Damn it.

Honey, what's going on?

They're just sick people.

Come on.

He's not my husband.

That person isn't Kim Byeong-cheol.

That man's name is Oh Tae-seok.

He's that woman's husband.

He came here in case I tried to kill his pregnant wife.

Jeong-u.

I...

I'm...

I'm the other woman.

What are you saying?

I was told what you said.

You wanted him to end the affair.

Jeong-u saw me with Chae-rin.

He wanted me to end the affair.

Chae-rin is pregnant.

I think it's time.

What is wrong with you?

You wrecked my car.

I can't believe this.

Mom.

Why are you crying, Uncle?

Is Mom hurt?

No.

It's okay, A-yul.

I AM SINCERELY SORRY...

What a sloppy suicide note.

Suicide note.

Suicide note?

- Where are you going? - To my place.

And here I thought you lived here.

MISEONG MOTEL

HELP WANTED: RECEPTIONIST MISEONG MOTEL

Hey, you! Sunglasses!

Why aren't you answering my calls?

What's your phone for?

Did the glasses look like this?

The glasses Seon-a was wearing. Are these them?

What do these glasses let you see?

S-line.

S-line?

So you're saying

someone took Seon-a's glasses,

called her to the school rooftop, and then pushed her.

she was threatening people about their S-lines.

Stupid virgin.

Teacher

Do you have a girlfriend?

I've had

many men as lovers in my life.

What exactly are these glasses?

They show who people have slept with.

Yet another gruesome murder took place

last night in Gangam-dong.

Could there be more than one pair of glasses?

The glasses might...

not be one of a kind.
