Get up, Uncle.

Come on.

Get up.

Leave me alone.

Kang Seon-a.

I never wanted much in life.

All I wanted was to be free. That was it.

But the things I wanted to be free from

were thrown at me like chores.

THE GLASSES

When did they...

That's unexpected.

Hey. Come here.

- Why? - Just get over here.

Lower your head a bit.

Why?

What's going on?

When did you meet your wife again?

In college.

What about before? Didn't you have any girlfriends?

- Of course I did. - How many?

One.

We are so different.

That's not anything new.

Why the new glasses?

Are you trying to see the world from a suspect's point of view?

They don't suit you at all.

Don't I know it.

Can I help you?

Bangju High School?

Yes.

Follow me.

- Get over here. - What the heck?

What gives detectives the right to do this?

Get a warrant.

Warrant, my ass.

I'm not arresting you.

I just want you to visit a friend.

I need to check something.

What friend?

And check what?

Come and see for yourself.

Stand here for a minute.

Damn it.

Am I free to go now?

Wait.

Do you know if Seon-a had any boyfriends?

Boyfriends?

Kang Seon-a?

I don't know about boyfriends,

but I know she has someone she hates.

Maybe it was you.

Stop fooling around.

You know what she always says.

"I'm going to kill that son of a bitch one day."

I think she hates that person even more than Kim Hye-yeong.

Isn't it Hyeon-heup's birthday next week?

What day is it?

November 1st.

Let's have a party!

I don't want to.

How come?

I've never had one before.

Sorry, but you don't have a choice.

Want to meet up before the party,

just the two of us?

UNKNOWN NUMBER

NOVEMBER 1ST. YOU ARE INVITED TO A BIRTHDAY PARTY.

NOVEMBER 1ST. YOU ARE INVITED TO A BIRTHDAY PARTY.

How's this color? I just bought it.

- It looks awful. - What?

- Wipe it off. - No way.

- You should. - Look, Ji-na's here.

Hey.

No practice today?

What brought you to school?

Nothing.

Why are you so quiet today?

Don't know.

- What's with her? - Weird.

Ji-uk.

I think there's a sexual assault case against a minor.

Su-min can handle that.

I think it'd be good if you gave her a hand.

Who's the victim?

A week ago...

I went to this boy's house and we drank together.

We used to be K-pop idol trainees together so we were close.

We were drinking...

and I blacked out for a while.

When I woke up...

I noticed my underwear

was on back to front.

What about the boy?

He had sent me a text that he was going out.

Had you had sexual intercourse before the incident?

No.

Why is she lying?

What do you mean?

Huh?

Nothing.

Let's go see the boy in question tomorrow.

- Quick. - We have to hurry.

Kids these days...

Even I wasn't like that in high school.

What are you mumbling about?

I said I'm fed up visiting schools.

I graduated years ago.

I know.

There seem to be a lot of school-related cases recently.

Detective.

Hello.

- Hello. - Hello.

A virgin?

No sex before marriage?

Nice meeting you again.

Except...

You being here can't mean good news.

How's Seon-a doing?

She's still in the hospital.

I wanted to visit her with the students. Would that be okay?

It's a little early for that.

I see.

You're wearing new glasses.

They look good on you.

Yeah, right.

Your ears are red.

Do you know Seo Han-yu in class 7, year 2?

Han-yu? Yes.

Seo Han-yu.

How do you know Yoon Ji-na?

She's just...

a girl I know.

We used to be trainees together.

On the evening of September 20,

did you drink together at your place?

- Yes. - Where were your parents?

They're abroad.

I came to Korea to become a singer

and now I'm living by myself.

Do you think it's okay for you high school kids to drink?

You seem pretty cocky.

Sorry, Detective.

I was stressed out from schoolwork.

You're here as a suspect in a sexual assault case.

Are you aware of that?

Is that what Ji-na said?

I never slept with her.

I don't want to.

Kids these days are really something.

With such innocent faces, too.

We'll get something once we start digging.

Are you done staring at me?

I was going to tell you first.

Give them here.

They're evidence from a case. I can't just give them to you.

And it's okay for you to wear the evidence?

I need to test them out.

Isn't that for the KCSI to do?

Yes. You're correct.

As soon as I put these glasses on,

I realized you were telling the truth and got goosebumps all over.

It's a relief, isn't it?

I trust you, and you trust me.

I don't trust you.

Get rid of the glasses now.

Calm down.

Detective, haven't you learned anything from Seon-a's case?

And remember my neighbor?

You said you found the glasses at a crime scene.

Don't you get it?

Every case is related to them.

Wearing them is dangerous.

You're pretty convincing.

All the more reason for me to try these on.

- And how could they be dangerous-- - I'm not saying the glasses are.

You don't know how they're going to change you.

What's going on here?

Is something wrong?

Nothing's wrong. She lives in my neighborhood.

Hyeon-heup's a special kid.

Would you like to have dinner with me sometime?

Sorry?

I'll call you.

Hello. You're here nice and early.

Please, take a seat.

Yoon Ji-na.

I discovered her myself.

But she didn't try very hard.

So I told her to quit if she didn't have her heart in it.

I'm not the type to force people into doing something they don't want to.

What was Ji-na like?

I'm embarrassed to say this,

but she wasn't that talented.

She should have tried harder to make up for that.

But she didn't push herself.

On top of that, she liked hanging out with her friends too much.

She'd always talk the other trainees into drinking with her

or meet boys.

It's no surprise she didn't make it.

We shouldn't rule out the possibility that it's a false accusation.

Don't make any assumptions yet.

My head hurts. I hate these kinds of cases.

What do you mean?

The "he said, she said" type.

Plus, they're both minors,

and the case is sensitive in nature, so we can't really interrogate them.

We need something like

a foolproof lie detector.

Strange.

- What is? - It doesn't make sense.

What are you talking about?

It's nothing.

By the way,

do you have a crush on Seon-a's homeroom teacher?

What?

Where the heck is this coming from?

Never mind if not.

She was annoying.

Always calling me up, wanting to see me.

I'm going to be a senior soon

and not even a trainee anymore.

Can I see your text messages?

Go ahead.

JI-NA: I'M EXHAUSTED. CAN I COME OVER?

RIGHT NOW? JI-NA: YES. ARE YOU BUSY?

JUST A LITTLE...?

JI-NA: I WON'T STAY LONG. I'M SO DEPRESSED.

ARE YOU COMING RIGHT NOW? FOR A DRINK? JI-NA: YES!

You deleted your texts,

washed the clothes

and the bloodstained underwear you were wearing that day,

and filed charges only after a whole week passed.

Did it cross your mind

that these circumstances wouldn't play out in your favor?

I already told you.

I didn't want to believe what happened was true.

You might be charged with false accusation.

Detective.

It was me who washed Ji-na's clothes.

It's not Ji-na's fault.

DONG-SIK: NOTHING MUCH TO GO ON HERE. I'M SENDING HAN-YU HOME NOW.

Please excuse me.

Yoon Ji-na.

I'm asking you for the last time.

Were you coerced into...

I mean...

Did anything actually happen between you and Seo Han-yu?

Don't transfer this case to the Prosecutors' Office.

What?

"Hey, Sunglasses."

Not calling me that today?

When did I ever?

This is for you.

It's not exactly a gift, but still.

I read your case file.

What happened to your parents is not your fault.

In case that's what you were thinking.

So that's what she looked like.

She looks different from what I remember.

Do you want to find her?

Seon-a said

if she were alive, she'd have come to see me.

Like you said, these glasses

may be dangerous,

but I'm positive they can help someone out.

Just like you saved that woman in apartment 204.

Who is it that you're saving now?

Do you know Yoon Ji-na? She's in your class.

Yes.

She reported someone for sexual assault.

The case has been dismissed.

I used these.

There was no S line between the two.

Yoon Ji-na said she had no sexual experience,

but she had four S lines.

I knew you wouldn't make it as a K-pop idol.

- Serves you right. - Serves you right.

Yoon Ji-na

could be telling the truth.

Just a week ago, she didn't have any S lines.

Hello?

Have you transferred the Yoon Ji-na case?

No, I'm working on it.

- Wait till I get there. - Why?

We're going back to square one.

This doesn't feel quite right.

Seo Han-yu.

It's the police. Are you home?

Seo Han-yu.

- You... - Hello, Detective.

Can we come in?

Sure, go ahead.

You keep a tidy home.

Yes.

I'm a bit of a clean freak.

Did you drink

over here that night?

We started there, but she blacked out,

so I put her on the bed.

Okay.

Are the bottles you drank from still here?

No. I don't keep things like that.

Detectives.

I have an early morning tomorrow.

Can I get some sleep?

CLOSED

MISEONG MOTEL

I went back to the scene just in case

and found the glasses in the bathtub.

What if someone intended

for you to take the glasses?

Impossible.

How could they have known I'd be back?

You can't expect things to make sense.

Like the fact that I see S lines

or those glasses.

I know someone put the glasses at the crime scene on purpose.

Who could it be?

- How did you... - I just...

I saw you while I was passing by.

I wondered what was up and followed you,

but you disappeared around here.

You weren't taking my calls.

What brought you back here?

I left something during my shift.

Aren't you scared? It's creepy here.

Remember?

I told you I could see weird things.

Yes.

There's something

above your head--

Stop.

If I were to get

an S line,

I think it'd be okay if I saw things...

What?

...as long as I'm with you.

Starting the day with grueling work. What a morning.

This looks okay.

Found it.

Okay. Thank you.

How long is the forensics going to take?

A day at the shortest.

How did you get the idea of looking for the bedsheets?

The sheets...

The color bothered me.

It didn't match the interior.

He threw away perfectly good sheets

not in the trash, but a clothing donation bin.

He's got something to hide.

Except...

There's something I can't figure out.

Humans acquire deviation from interacting with others.

Seo Han-yu.

Get over here.

Make it quick!

Don't I get to eat? I'm starving.

I'm going to ask you again.

Why did you throw out the sheets?

I'm a clean freak.

I can't sleep on used sheets.

I've already told you like five times.

How did Ji-na's blood get on the sheets?

I have no idea.

Maybe she had a nosebleed.

Or got her period.

Han-yu.

You see...

I know you didn't do anything.

I totally believe you. Want to know why?

Good-looking guys like us can't keep girls away.

Yoon Ji-na came on to you first, right?

Though you weren't that interested.

I told you the truth before.

She's not my type.

There are people who say she's hot,

but not me.

She insisted on coming, so I let her.

I had some whisky left,

so I gave her that and she drank all of it.

You have whisky at home?

What brand?

I'm a whisky drinker myself.

Glenfiddich.

And then what?

She downed the bottle,

got herself drunk, and said she didn't want to go home.

She even wanted another drink.

So I got her a beer from a convenience store.

She passed out after that.

Mixing drinks is a bad choice.

How were you able to buy the beer?

The convenience store never checks IDs.

Go see for yourself.

Glenfiddich, my ass.

Ji-uk.

The only usable surveillance camera footage is from the parking lot.

With the number of residents in the building, there's a lot of traffic.

The time Ji-na entered the building,

the time Han-yu went out and came back,

and the time he left in the morning all checks out.

How long was he gone to get the beer?

Five, ten minutes?

If somebody intruded during that time slot,

the S line can be explained.

That would mean she had passed out before drinking the beer.

What line?

It's nothing.

Hey, stop it right there.

When did these punks get in?

About an hour ago.

There.

Weren't there cameras at the back of the building?

No.

Rewind.

One, two, three...

One, two, three, four, five...

From six to seven lines.

Four to five lines.

One, two, three...

Fucking punks.

So that's Ji-na?

Bring them with you.

Do you have cigarettes?

- No. - Not again.

You can't be serious.

DETECTIVE HAN

SUNGLASSES

Fuck. I don't have the time for this.

I want a lawyer.

- What are you typing? - Hey.

Please, can't you just let me go home?

I didn't do anything.

Let me go. Please.

My mom's going to kill me.

Please.

Okay, I'll drive you home. Come on.

Detective.

I live in the opposite direction.

Yes, I know.

Where are we going?

What do you think of this car?

Pretty smooth, isn't it?

Can you just tell me where we're going?

God, this red light is crazy long.

Why are we here?

Is this place familiar?

Detective Oh, come with me.

Okay.

What should we have for dinner? Maybe get some soju?

Ji-uk.

We don't have much time.

We have to let Seo Han-yu go soon.

Also, we don't have cause to keep that kid in custody.

Good. Keep talking.

But try to keep a frown on.

What for?

Isn't it obvious?

He's ready to piss himself.

All we need to do is wait with a dead serious face.

I say

he'll break in ten minutes.

Hey, Beom-ju. Get out of the car.

- What? I don't... - Just get out for a minute.

Where are you taking me?

It's not far. It won't take long.

Where are we going?

Can't you please just take me home?

We'll have a look around the crime scene,

and we'll go back...

Damn it.

Now that's a confession.

Fucking prick.

He's a super fast runner, isn't he?

Yes.

- Detective. - Yes?

I really want to go home.

I'll take you. But we're going back to the station first.

Why? What about the other guys?

I sent them home.

How come?

I didn't have much on them.

What about me? Why can't I go home?

You...

I think I've got enough on you.

No way.

You can't do this!

You can't do this!

Damn it!

Calm down. You're going to get hurt.

Jerks.

Detective.

I won't get detained if I'm absolutely honest, will I?

Well,

that depends on what you say.

I did do it,

but it wasn't just me.

It's not my fucking fault.

That scumbag Han-yu planned everything.

I was always on about how hot Yoon Ji-na was,

and one day the guys called me up.

They asked how much I'd pay to do it with Yoon Ji-na.

I only went there because I wanted to drink with her.

She was out cold because Han-yu had drugged her.

Detective, it was Han-yu. He told us what to do.

It wasn't...

It wasn't just me. We were all in on it.

Can you let me off just this once?

That asshole Han-yu planned the whole thing.

I only did it because my friends said to!

Han-yu was sitting there watching us the whole time, the pervert.

This is yours, isn't it?

- What is it? - I found it in your room.

As if. It was in the fire extinguisher cabinet.

Did you use this to drug Ji-na?

Do you have proof I did?

I just had this for a laugh.

Let's see if the judge thinks it's funny, shall we?

The other kids came clean.

You have four witnesses against you.

I'm not the rapist.

Those scumbags are.

Sure, you're right.

But you're the ringleader.

You creep.

Detective.

Will they be punished?

I did everything I could.

The court will do the rest.

Putting these glasses on the judge would definitely do the trick.

Wearing the glasses

doesn't let you see the truth.

I suppose.

If I get tons of S lines like you,

I might become more indifferent.

Is this an insult?

NURSING HOME

You can walk home from here, can't you?

Something urgent came up.

Sure.

YOO JUN-SEON

When did he go missing?

This isn't the first time. Are you sure he isn't here?

I... I think...

I found him on the roof the last time.

I think you need to come and see this.

We haven't seen her before,

and we don't know how she got in.

Seon-a's homeroom teacher?

UNKNOWN NUMBER

Dong-sik.

Run a background check on Lee Gyu-jin.

Father...

How did you get here?

Seon-a...

What the hell is going on?

This is fucked up.

Get your hands off her.

Get them off!

What did you do to Seon-a?

Say something, for fuck's sake!

Ji-uk...

You fucking...

How could you...

to Seon-a!

What have you done?

How is she supposed to live with this?

Detective...

I need your help.

ask you a favor.

You can say no if you want.

Do you like me?

If I were ever to be with someone,

I wanted it to be you.

WHO ARE YOU TALKING TO? ARE YOU IGNORING ME?

REPORTING ME WON'T GET RID OF THE VIDEOS

IT'S OVER FOR YOU, YOU SLUT

I think

you dropped these earlier.

Detective...

I need your help.

I ran a background check on your homeroom teacher,

but nothing came up.

Lee Gyu-jin doesn't exist.

The lines above people's heads.

You know what they mean, don't you?

It won't be long

until the whole world is bathed in red.
