Second Sister (망내인: 얼굴 없는 살인자들)

(Agreed by Crown Culture Corporation)

(Shocking news! Jieun jumped from her balcony!)

("A high school girl jumped... Police are investigating")

(Don't worry. It's not our fault.)

Stop!

Hello, I'm...

What do you want?

PI Jung told me about you.

So early in the morning.

Totally ruined my sleep.

Sir, are you Seol Jungyeong?

I'm not your sir. Call me PI Seol. Sit.

Explain in five minutes.

- What? - Miss.

I need a rundown before I accept.

Right, sure.

Four months ago, my sister was groped in a bus.

The groper was Shin Jeongman.

(Man in His 40s Jailed for Molestation)

After he was sentenced six months in prison,

I thought it was done and dusted. But then...

Shin's niece claimed his innocence

by posting a long statement on an online forum.

It said Shin simply lectured

my sister for smoking near a bus stop.

It also said out of spite,

my sister wrongly accused the man.

It even stated a vile rumor at my sister's school

about my sister being an orphan

who hangs with delinquents

and that she's a sugar baby

who does drugs.

The statement got reposted everywhere,

exposing my sister's school and her photos.

People only listened to the niece.

They bashed my sister in all kinds of ways

with vicious, uncalled-for words.

Then, I realized.

Anyone can easily be a demon online.

(High Schooler Commits Suicide from 12th Floor)

Because of the anonymous post,

my sister was torn to pieces.

Because of the niece's post,

my sister eventually killed herself.

After her suicide,

I hired a PI to find the niece who posted.

Shin Jeongman has no sibling.

He's an only son.

I found out Shin can't have a niece.

Then, the PI said this case needs

an ingenious hacker as a PI.

He recommended you.

Sir...

PI Seol. I have to find the poster.

I have to know why she posted

and had to force my sister to die.

I must ask.

I'm going to decline.

- Why? - It's too easy.

Too easy?

A few clicks on the keyboards will do.

I won't waste my precious time on a dull case like this.

A dull case?

Yes, dull.

That's below the belt.

Time's up now. Can you leave?

I have to have breakfast.

Aren't you leaving?

Starting up as a small software company in Silicon Valley,

SIQ is a global IT venture company today.

It has intrigued many people.

First, SIQ was founded by three people

including you, Steven.

Two other founders are publicly representing the company,

but you work mostly in the shadows.

Is there a special reason?

Excuse me, PI Seol!

Hello.

If you can pay 20 grand, I'll do it.

- Where did you find my number? - Can you pay?

I'll pay.

But you must

find her in one week.

Okay, I'm in.

We're on the same boat. I'm going to talk real with you.

By the way, why did you suddenly change your mind?

This case seems more interesting than I thought.

It's the log-in record of the online forum.

Give me some room!

Look at this. It shows the same screen.

This is the log-in location.

This is ID kidkit727's IP address.

I tried to track the IP...

Do you know what IP is?

I'm not a dummy.

I guess.

I tracked the IP address.

It's in Luxembourg.

It can't be tracked.

Then, we can't find her with the IP address.

I could try with her email, but...

She signed up with an untraceable account.

I don't know what she's hiding,

but she's a pro.

Then, how do we find her?

We'll have to dig into Shin

to see how connected they are.

(You're doing it again. Stop this self-sabotage.)

(It was her choice to kill herself.)

(I ain't sorry for someone who throws people under the bus.)

(I swear the police can't find us.)

(They have no evidence. How can they find us?)

(You know how good I am. Don't worry a thing.)

Shin and kidkit727 have no connection.

How can that be?

I checked Shin's cell and computer usage.

He wasn't tech-savvy.

He would be online to play a game of Go.

His wife, too. They're not hacker materials.

From the way kidkit727 wrote the post,

did you not notice anything peculiar?

"Peculiar?"

It read like a defense written for the defendant.

The legal representatives for Shin

and kidkit727 might be connected.

I'll dig deeper into this.

But I have a more promising lead.

Yun Jieun, your sister.

I want to check your sister's cell.

(Yun Jieun, I know you well. I've been watching you.)

(You just wait. I'll yank your mask off.)

(I'll show the world what a vile wench you are.)

(So don't even think about

(making excuses for your sorry ass.)

(Girls like you only learn the hard way.)

(Because I'm about to spread this photo around.)

(People who know you will find out I posted the truth.

(Bullcrap. Jieun, I'm proud of what I did.)

(You lied to frame a person. I'd die than be shameless.)

(Sender Jieun: Do you want me to kill myself?)

What are you doing here?

Things are looking up.

- I got another IP address. - From where?

Korea.

Then you can get the exact location.

She slipped this time.

But she isn't dumb enough to show herself.

We have the IP address. Why can't we get her location?

She sent four emails

and gave away three IP addresses.

The first two have the same address.

The last two don't.

Different Wi-Fi was used to access internet.

She kept changing locations to send the emails.

Can we narrow it down to an area?

The first two were sent in Hanam-dong.

The third one, in Oksu-dong.

The fourth in Seongsu-dong.

But the Wi-Fi was logged in by a prepaid cell.

We can't track it down.

- Then... - But...

One of them can be found easily.

"One of them"?

Two people are behind kidkit727.

How do you know that?

Well, let's call one, "Seven".

Based on the ID, kidkit727.

I'll call the other one, "Rat".

Seven is probably the mastermind

who wrote the post and emails.

Rat probably provided technical support,

but you might ask,

"On what grounds?"

The posting

and emailing were executed so differently.

One falls short a lot.

Then what do you mean we can find them easily?

We find Galaxy users from Jieun's school.

Seven is one of them.

But wait.

Are you saying one of Jieun's classmates did this?

The answer is in Seven's email.

Think about it.

Why do you think Seven rashly blackmailed Jieun?

She could've waited for Rat

to send it more stealthily.

It's simple. Seven was impulsive.

Seven couldn't hold it in.

What is the last sentence of the first email?

"You'll never smile again after this."

People give away information

when they talk or write.

Like a habit they don't notice.
