RED LINES THAT CONNECT SEXUAL PARTNERS

So if

people make love...

I mean...

If people have sex, they're connected by a line.

And wearing these glasses lets you see the lines?

You said you could see them since you were born?

Come on!

Stop joking around.

I know you high school kids are out of control,

but I'm a detective.

Don't underestimate me.

I knew you wouldn't believe me.

Hey, wait.

I never said I didn't believe you.

So you're saying

someone took Seon-a's glasses,

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

Possibly.

Who? And why?

I don't know.

Seon-a isn't someone who would kill herself...

but she threatened people about their S-lines.

She had a lot of enemies.

Do you think it's possible

there's more than one pair of glasses?

Recently, there's been a series of cases similar to the one that happened

in the apartment above yours.

What am I doing, telling a high schooler this?

Wait.

So you see a red blur everywhere?

Yeah.

More or less.

That explains the sunglasses.

It couldn't have been easy for you.

Seon-a.

Kang Seon-a.

What are you doing?

Stop sleeping in class.

Let's focus, everyone.

So we have autosomes and sex chromosomes.

There is one pair of sex chromosomes and the remaining 22 are autosomes.

Autosomes determine our...

Come on, run!

Are you okay?

Why? Well...

She screamed in class when she woke up earlier.

Listen.

It's because you haven't been getting enough sun.

Let's go somewhere fun this weekend.

I can't. Why not?

You don't want to? Or you can't?

I have plans.

What plans?

I got a part-time job.

Really? What kind of job?

Stop bothering her.

Maybe she doesn't want to tell us.

It's at the Miseong Motel.

Miseong Motel? Miseong Motel?

Ms. Kim Mi-seong.

Yes?

This was your second attempt.

How can you make the same mistakes?

You're driving me crazy.

Do it again.

I'm sorry.

Stupid virgin.

They have the best nuggets there.

You should try their rolls too.

Where did you grow up, Mi-seong?

In Busan.

But you don't have an accent.

I worked on it.

Why?

Because I'm trying to get into acting.

To become an actress?

Yeah.

A casting director approached me once.

Is the music teacher dating anyone?

Why? Are you interested?

He's cute.

Should I ask him for you? Yeah.

Do you think he's single?

Just finish your lunch.

MISEONG MOTEL

FRONT DESK

NO MINORS ALLOWED

Hi. A room, please.

That'll be 30,000 won.

Can't we go to a proper hotel instead?

We're only staying for a few hours.

Thank you.

You always say you'll take me somewhere nice.

I'll take you to a hotel next time.

Seon-a's bully, Kim Hye-yeong...

pushed Seon-a off the roof and ran.

Except she's completely disappeared.

No credit card or phone activity.

Or...

the Korean teacher

pushed Seon-a off the roof

and killed himself out of remorse.

That's the most likely scenario.

His cell phone signal was detected at the school.

Except the Korean teacher was basically missing

until his body was found.

And his family says he had severe acrophobia,

making it impossible for him to push someone off a roof.

If what they're saying is true.

Then who could it be?

Ji-uk.

Could Seon-a have...

KANG SEON-A

It wasn't a suicide.

I'm not just being stubborn. Something's bothering me.

THE GLASSES?

Seon-a changed when she started wearing the glasses.

What exactly are these glasses?

Listen to this.

They show you who people have slept with.

Are you serious?

You think so?

What are you guys doing here?

Do you want a room for the night? Yeah.

That'll be 60,000 won.

Ta-da!

How did you...

Friends come to see their friends at work.

You can't be here. You're minors.

Hey.

You too.

Exactly. It's illegal.

I know.

Do you have any customers?

Can I go up and see?

Hey! Wait!

Keep it down!

Guys, stop it.

It's so cramped in here.

There's so little room.

Stop it.

Why did you want to come in, anyway?

It's fun.

It's exciting.

A room, please.

I'd like Room 206.

Did she come alone?

I'm sure I know her.

It's true.

I've had many men

as lovers in my life.

But...

ever since I saw you,

sleeping with strangers

could no longer fill my empty heart.

I was afraid

I'd never be able to...

have you.

I want to have sex!

You're crazy.

You don't even have a boyfriend.

Not right now, but I've had plenty.

You mean the guys you stalked?

Look who's talking, Mr. Virgin.

What? I knew it.

What? The woman who came in alone.

She works at the school's admin office.

You know, the one with the glasses.

Are you sure it's her?

She looks so different.

But she can't escape my eagle eye.

Keep it down, will you?

HWAGYEONG-DONG MARITICIDE CASE

It's Shin Hyeon-heup.

Her mother killed her father and ran away when she was a child.

KILLED HUSBAND WITH KITCHEN KNIFE

VICTIM WAS DOA

SUSPECT LEARNED OF AFFAIR WITH SISTER SUSPECT'S CHILD HAD DRAWN

IMAGINARY LINES TO DEPICT THE ADULTERY SCENE

Am I being led on by some crazy girl?

CHILD HAD DRAWN LINES TO DEPICT THE ADULTERY

I have a few questions.

Does Seon-a...

have S-lines too?

Isn't that Seon-a's private life?

So that's a yes.

Is Seon-a's S-line connected

to that boy in your class, Ji-won?

No.

I don't know who it's connected to.

But...

it's not someone from our class.

Damn it.

Do you think the guy connected to her...

is the one who pushed her off the roof?

Well...

I'd say it's a possibility.

Another gruesome murder took place

last night in Gangam-dong.

The suspect was apprehended not far from the crime scene,

but only after the victim had died.

The apprehended suspect didn't hide his smile

and said he was purified,

leading to speculation of psychosis...

Could there be more than one pair?

The glasses might not be...

one of a kind.

MUSIC ROOM

Sorry.

The music is so beautiful.

I couldn't help myself.

It must be nice,

knowing so much about music.

It doesn't do me any good.

I spend every day with high school kids.

You're Mi-seong, right?

You remembered. Yeah.

Do you have any dreams?

Guess.

I get the feeling you don't want to stay here.

An actress, maybe?

Did I get it right?

Yeah. How did you know?

I figured you'd be good at anything that uses your body.

You're right.

It's so unsettling.

I know I can be good at it.

It's something you're born with.

I guess so.

Are you heading home?

Yeah.

Where's Gyeong-jin?

Something came up, so she left.

By the way...

are you free today?

You seem to like empty places.

How did you find this place?

I was on the swim team in middle school.

I'm not anymore,

but I used to come here to swim sometimes.

Do you know how to swim?

No.

Hey, are you okay?

Look at us.

HOT NOODLES

It's ready. Let's dig in.

It's good.

Are you sure we can eat here?

Yeah, as long as we don't get caught.

If Gyeong-jin were here,

she would've brought a portable stove.

By the way,

why did you jump in earlier?

It's okay if you don't want to talk about it.

Sorry.

Ever since

I was little...

I've been able to see weird things.

I can see red lines

above people's heads.

Like this?

Yeah.

Do I have one?

You don't.

It's the same for me

and Gyeong-jin.

Do you believe what I'm saying?

Yeah. How come?

Why would you lie?

I'm weird, right?

Yeah.

You're not ordinary.

I knew it.

I think you're cool.

I'm way too ordinary.

No one would know if I disappeared tomorrow.

If you did,

at least Gyeong-jin and I would know.

You're right.

I keep telling you. It wasn't me.

Do I look like a con artist,

Ms. Kang Su-min?

Hey.

It's been a while, Ji-uk.

It has.

Why haven't you answered my calls? I missed you.

Well...

I can't be seen talking to a criminal.

Since when was I not one?

You were just a suspect before.

Still so picky?

I'm done here, right? Can I go?

Fine.

Answer my calls.

Ji-uk, since when do you...

Mind your own business.

LEE JI-WON

KANG SEON-A

BOYFRIEND?

Ji-uk.

You're not seeing anyone right now?

Since when do I date anyone?

Well, not technically, but you always kept yourself busy.

I guess.

Taking a break, maybe?

There's someone who intrigues me.

But not sexually.

No way. How so?

What do you mean?

Can't I just be curious about someone?

I'd like a room.

Room 206, please.

It's true.

I've had many men as lovers in my life.

It's true.

I've had many men as lovers in my life.

It's true.

I've had many men as lovers in my life.

It's true.

I've had many men

as lovers in my life.

At first...

I was happy just to have enough space to lie down.

I was confident I'd become a famous actress very soon.

But soon...

my ears started to hurt.

It wasn't because I could hear people in the other rooms.

The problem was me.

I was afraid that the sound

when I talked and moved

would reach other people's ears.

It was the same at school.

I was afraid someone would hear me

giggle whenever I saw you.

That's when I found this place.

An old motel that was sure to have no customers during the day.

I was free in this room.

And one day, I found the glasses.

I was perfect when I looked at myself through them.

And all of a sudden,

I became an observer.

This room is perfect.

A perfect world

for the perfect me.

Hey.

Why a motel, of all places?

Like old times.

It's refreshing, I guess.

Didn't you miss me?

I can see you on TV whenever I want.

You're so funny.

Leaving already?

Same time tomorrow?

JOON-SEON: AT MISEONG MOTEL TONIGHT? YES, I'M WORKING NOW.

CAN I COME SEE YOU?

I'd like to stay longer.

Which room?

Room 206.

What do you think? Does it look good on me?

Hey. Hi.

You're here early.

Mi-seong?

Wait.

This music...

We listened to this together, right?

How did you know I was here?

You see...

I have a confession to make.

What?

I've had

many men

as lovers in my life.

What are you talking about?

It's true.

I've had many men

as lovers in my life.

But...

ever since I saw you,

sleeping with strangers could no longer fill my empty heart.

I was afraid

I'd never be able to...

have you.

You're disturbed.

You've lost your mind.

It's true.

I've had many men as lovers in my life.

Did you just throw that at me?

I did.

Oh, my God.

What's happening?

I don't feel so good.

I put something in your water earlier.

You'll be fine in a moment.

It's true.

I've had many men

as lovers in my life.

But ever since I saw you,

sleeping with strangers

could no longer fill my empty heart.

No, no!

Oh, no.

Please...

It's true.

I've had many men...

as lovers in my life.

Are you okay? Holy shit!

Some crazy bitch beat me up

and stole my clothes.

Where is she? That fucking bitch!

It hurts. Please, call the police.

Did you find any glasses at the scene?

No.

Did you see those people's S-lines?

The admin worker still only had one.

But it wasn't connected to the music teacher.

Why on earth would someone do something like that?

I don't know.

And I probably never will.

Do you think this case has something to do with the glasses too?

I think...

the glasses she always wore at school

are the ones we were looking for.

Whenever she came here,

she looked completely different from school.

She probably thought she was special

after she started wearing the glasses.

Detective.

It applies to everyone, without exception.

That's why the glasses are dangerous.

KANG SEON-A

Detective.

It applies to everyone, without exception.

That's why the glasses are dangerous.

I was going to tell you first.

Give me that.

As soon as I put on these glasses,

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

I don't trust you.

Get rid of the glasses.

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

Did you have sexual intercourse?

No.

Why is she lying?

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

Detective.

A virgin?

You're wearing new glasses.

Would you like to have dinner with me sometime?

Pardon?
