Our Seong Youn High School is challenging the world's best high schools over Korea.

We have the best facilities and the best curriculum.

...A B and C. It's a very simple question. What tangent means?

A divided by B.

Most of the math classes are being taught in English.

Out of the 600 kids in a class, more than half of them go on to IVY League schools.

The rest go to schools here in the country,

but the best schools are those in Seoul.

Because finals week is very close,

if you want to go to a college, then the tests are very important. Because finals week is very close,

if you want to go to a college, then the tests are very important.

We have no time to worry about other stuff.

The student's food is prepared with care and has many healthy ingredients.

Fatty foods and fast foods are not allowed.

-She must be crazy! -What is she doing?!

What is she doing?!

What are you doing?! Turn the camera off! Turn it off!!!

Episode 7

Reporter Gu Yeon Joo, the youngest Seoul City Police Captain in the Uri newspaper.

Good morning.

Before Woo Hyun was in the squad, she was a reporter here.

I tried to hack her laptop, but she had strong security on it.

She had vaccine programs going around the clock and she never opened any email attachments.

If she did date Woo Hyun, then putting security on her computer would be normal.

For now, there isn't any evidence that they were really dating.

That woman... knew the password to Woo Hyun's house.

But Team Leader Kim Woo Hyun didn't say anything about dating someone.

Are you getting jealous because of a dead person?

If Woo Hyun and Reporter Gu Yeon Joo really dated,

then she would be the first one to know that I'm not Woo Hyun.

And that woman is really close with the police station.

On top of that, when the Dae Young Team disappeared,

On top of that, when the Dae Young Team disappeared,

all the evidence that we had went away.

What's important to me right now, is that.

Now on this file...

all I have to do is extract the file that's hidden in it.

Like you said, Director,

there must've been some kind of misunderstanding.

To be honest, I...

It couldn't be... in here...

119... 119.

The phantom file that was in Shin Hyo Jeong's laptop...

If I could just find out who the person that died was...

When you saw Director Nam Seo Won, did you notice if anyone else came here with him?

No, without any reason, he came here by himself.

May I see the check-in list?

Our resort only has VVIP coming in.

We only rent the units. We don't have a check-in list.

But why are you talking about something that happened a year ago?

Is there some kind of problem?

No.

The past CK Director and I were like father and son.

We gave each other information when either of us needed it.

But early last year, while I was on a business trip, he left a message for me.

I've been calling you but I haven't heard back.

I have important information.

I'm being watched right now.

If they know that I gave a tip-off, I will be in danger.

Please call me as soon as you can.

What's the important information he was talking to you about?

Who knows.

I don't know. When I got back from the business trip and heard the message,

he was already dead, with a heart attack.

Then...

Then...

what do you mean when you said that Kim Woo Hyun has a secret in this case?

I thought that the death was kind of strange, so I went to see his family.

But then, do you know what I found there?

[Inspector Kim Woo Hyun]

So, Nam Sang Won and Kim Woo Hyun knew each other?

Kim Woo Hyun said that he didn't know who Nam Sang Won was at all.

But...

What is this?

The day that Nam Sang Won died,

it's the CCTV that was near the resort, and he's on it.

There isn't any evidence of Kim Woo Hyun and Nam Sang Won meeting that day.

But... Kim Woo Hyun definitely has something to do with the death of Nam Sang Won.

As you look into it more, you'll probably be able to catch Kim Woo Hyun.

Do you still have CCTV captures from a year ago?

No. We only have them up to the last 6 months and then they're thrown away.

Ohh, you guys use Sa Sul Security.

Yes.

But the angle that the CCTV's are at....

Huh? It's kind of strange.

I guess you guys intentionally don't make captures of the doors to the houses.

Yeah, that's because the customers don't want it. But instead, there are CCTV's here and there.

We protect the inside of the unit, but we do a strict watch outside of the unit.

So you're saying the security outside is tight, right?

If you remember anything from then, please call me.

Yes, sure.

Please, it's a favor.

I understand.

Yes, it's Hae Myung Resort.

There's someone snooping around the Nam Sang Won case from a year ago. Yes.

It's Team Leader Kwon Hyuk Joo, from the Cyber Team in the police station.

Oh alright. If he comes again, please tell me.

Lieutenant Kim.

Here's something from Safe Tech about the DDoS attack.

They made it really well.

They made it really well.

Has Safe Tech always been this good?

From what I knew, they weren't all that great...

But then all of a sudden, they got better.

The people that did this are Safe Tech?

Yes.

Where are you going?

I'm going out for a bit.

Bye.

Bye.

Yoo Kang Mi - Seong Yeon High School case.

- Hey, Tae Kyun. - Yes?

What is this? The Sung Yeon High School case... The one Yoo Kang Mi went out to.

- Ah, it seems that a student commited suicide. -Is that so?

Wait a sec... If it's Sung Yeon High School...

Sung Yeon High Case. Ji Won.

Sung Yeon High School.

Subtitles brought to you by Cyberghosts Team @Viki.com

The student that died is this student?

Yes.

His name is Seo Jin Won. He was in his third year at Sung Yeon High.

Since it was night, there wasn't anyone that saw him fall, but we think he fell from the roof.

On the roof, this student's ID card was there.

Why is his hand like this?

From what his friends said, they said that he hurt his hand in art class.

Well, since we don't know if he was bullied or not, we're investigating that.

Something that was a bit strange, is that all the e-mail he got were deleted afterwards.

How about the deletion time?

It was 10 minutes after the suicide.

Someone else cleaned it up.

You should go and check up on that yourself.

No!

I'm sorry,

but I know this rooftop very well, too.

Why did you do that?

Even though a guy from our school died...

the teachers are saying that the finals are soon, and

they didn't even let us go to the funeral.

I didn't think that was right.

I just wanted to show our thoughts as well.

Were you friends with Jin Won?

We weren't that close.

We just volunteered together at places.

Jin Won, what kind of kid was he?

By any chance....

was he ever bullied? Is that why he commited suicide?

Jin Won didn't die because of stuff like that.

If he didn't die because of stuff like that, was there a different reason he did?

I heard Jin Won got the Legendary Answer Sheet.

The Legendary Answer Sheet?

The Legendary Answer Sheet?

I'd love to get that! I hate midterms!

-Me too. -You always get first place! You don't need that.

Nu uhh...

What is it?

Get the teacher over here! The teacher!!!

Someone call the police!

Call the teacher! The teacher!!!

Didn't you say that you graduated from our school? Do you know anything about the answer sheet?

You know, right?

The number one in their class just became a junior and

I heard she commited suicide in the bathroom because of stress from the finals.

But... since then, whenever the finals started,

they said that her ghost appears.

That ghost picks one of the juniors and

puts in the answer sheet for the finals.

Whoever gets the answer sheet turns into number 1 in the class, and

it is said that they would commit suicide no matter what.

But... that's just a myth.

There's no such thing as the Legendary Answer Sheet.

No. No.

No.

It's true!

Jin Won said that he got that answer sheet.

What are you doing there?

3rd Year Class 5, Park Ji Soo.

The mannequin prank, you did it, right?

For now, go to the dormitory. And after the test tomorrow, come to my office.

It's been a while.

Yoo Kang Mi, right?

Yes, it has been a while.

That student wants to commemorate the dead.

It's frustrating. In that time, she could memorize another English word.

I heard you became a police officer.

Aside from all of the other great colleges you could've chosen, you chose the Police Academy.

I'm on the case about the kid that died, Seo Jin Won.

Are you curious if he was bullied or something?

Is it true?

This is Sung Yeon High School.

There is no time for bullying or anything else.

Just the final exam is coming closer. For the senior, GPA is their life.

Even just one little mistake could mess up all the hard work they put in the past three years.

There's no other choice but to be stressed out like that.

This is the original report of the June 12th case.

By the way,

what do you want to know about this report?

As I expected, it's great even if I see it again.

Safe-Tec invest a lot in the system, the facilities,

and people. It's just the result of our investment.

I heard that you merged with Se Kang Securities, right?

Money must be a good thing!

The analysis of malignant code, the pattern of DDoS attack...

everything is explained clearly.

If it was written by the suspect who did the DDoS attack, people will believe it.

Pardon?

What are you saying...

Could I accept that as a compliment?

Could you please

leave us alone for a while.

The report is very impressive.

If you had this good company,

why didn't you use it, when Se Kang had the DDoS attack?

No matter how much ability Save-Tec has,

it can't be better than the Cyber Crime Squad.

Or...

from the start,

did you already know there was no second attack?

What do you mean?

I heard, after DDoS attack, Safe-Tec earned lots of practical profit.

The stock price went up, and your rank in the industry also went up.

Isn't it a very profitable self-fabricated scenario?

Well, that's just if I were to write a novel.

Should I write a novel, too?

Let's say someone really plots a self-fabricated scenario like this.

Then, the National Police Agency, the National Intelligence Service and the articles...

Everyone would pay close attention to us.

I must say it could be a very dangerous self-febricated scenario.

So,

the reason for such a dangerous self-fabricated scenario is...

just to increase the stock price once?

Before the accident,

did we

meet often?

Still...

it seems you can't remember it.

When you remember,

please contact me.

You changed the password.

Do you want something to drink?

By the way,

if people get hurt, does their taste also change?

You never had alcohol before.

A thought occurred to me.

When we met in the Director's room,

again when I saw you here before,

you don't seem like

the Kim Woo Hyun that I knew before.

You said

we were in relationship.

It's because you suddenly did this.

I just remembered that I had an urgent matter.

I'll contact you again.

I'm not the only one.

There are more sympathizers inside the police.

The police, the prosecutors, and the press.

They are all are connected to him.

Woo Hyun knew

who killed Shin Hyo Jeong.

He covered for the true criminal.

If that Woo Hyun was alive,

the real suspect would definitely try to contact Woo Hyun.

They're going to

try to get in contact.

Wait, you didn't get off of work yet?

I needed to check something.

By the way, do you think Lieutenant Yoo will be fine?

I heard she had a bad experience when she was a student at Seong Yeon High School.

What 's that?

I heard that you first met her there at that time.

Oh, yeah.

What's with him? It couldn't possibly be dementia at that age.

I heard that she had a bad experience when she was a student at Seong Yeon High School.

Seong Yeon High School

Year 2003, Seong Yeon High School Kwon Eun Sol's suicide incident

Northern Police Cyber Investigation Team Leader Lieutenant Kim Woo Hyun

Seong Yeon student suicide... tried to recover the cellphone records...

I'm the Northern Police Cyber Investigation Team Leader Kim Woo Hyun.

You are the new Team Leader whom I heard of.

We had a tip-off that the student who committed suicide had a bully.

But the cellphone was destroyed because it fell down with her.

Can you repair it?

I will try. Is there any other digital evidence?

There are computers in the student's dorm.

Hey, student.

Eun Sol...

Eun Sool, I killed her.

I said I killed her!

Eun Sol...

What the Ilsan Police said is true.

Student Seo Jin Won,

all of his emails that have arrived within the past week were erased.

But that's something we don't know about.

The roomate wasn't in this room during the time the emails were erased.

I will have to check the travel route of the attached files.

The Legendary Answer Sheet?

What?

In a deleted email, Seo Jin Won downloaded a file called the Legendary Answer Sheet.

What do you mean by an answer sheet?

Is that some kid's prank or something?

Legendary Answer Sheet.hwp

2012 1st semester - Name: Cha Sue Yeon.

Legendary Answer Sheet.hwp

All the students who received the Legendary Answer Sheet

committed suicide.

Jin Won just committed suicide because of his stress.

There's no such thing as the Legendary Answer Sheet.

Teacher.

Again.

Oh my gosh, it's already the second time.

I know.

How did this happen!?

I heard a weird noise out here so I came out and...

But the same place as Jin Won....

Where is this student's room?

This student's room number is 504.

Recycle Bin

There are no emails in the recycle bin.

Subtitles brought to you by Cyberghosts Team @Viki.com

Who's first place?

1st place: Kwon Eun Seol. 2nd place: Yoo Kang Mi.

Eun Seol made 1st. Yoo Kang Mi...2nd place.

Eun Seol is first place?

Kang Mi, I raised my score!

Tell me the truth. Did you get the answer sheet or not?

I told you I didn't.

If not, then how did someone like you get 1st place over the school?

After suddenly getting a good score, you're acting like you're all that...

Kids like you don't have the right to listen to the lectures.

Girls, if I don't get into class this time either, then I'm in danger.

Please, please. Can you let it go just once?

Girls, please, please.

Kang Mi. Kang Mi. Kang Mi, please open the door for me.

Kang Mi. Kang Mi. Kang Mi.

Kang Mi, please open the door for me.

Kang Mi, girls!

Please open the door. Kang Mi. Kang Mi.

Kang Mi!

Kang Mi!

Kang Mi!

Kang Mi!

Kang Mi!

What are you doing in here?

Our school tuition costs $10,000.

For 3 years, $60,000.

Best education, best curiculum,

it is made by the parents' sacrifice.

That's why to live we study.

After giving all that money,

you can't just not be doing well in school.

Eun Seol's economic status wasn't good.

They barely got the money to let her come to school. They went into debt for her to come here.

In the end, because of us,

she died.

In the end, Eun Seol

chose to commit suicide.

That one time in our lives, we can lose,

and that we can trip,

no one taught us that.

If we trip,

we learned that, that's the end.

There wasn't such thing as the Legendary answer sheet.

Eun Seol just tried hard.

There was no legendary answer sheet when Eu Sol died, but now there is.

Dead Seo Jin Won had the legendary answer sheet.

Not Cha Soo Yeon, who died second.

I checked Cha Soo Yeon's computer. The email she had received within the week had been deleted like Seo Jin Won's.

But... there was no legendary answer sheet file.

Then, are you saying the kids dying has nothing to do with the answer sheet?

No. Then, are you saying the kids dying has nothing to do with the answer sheet?

No.

It is definitely related.

When you delete an email, you don't need to use the person's computer.

If you know the ID and password, you can delete it from a different computer.

Why?

Who is it?

What's going on?

Wake up a bit!

-Hurry! - Teacher, hurry please!

-Wake up! I said wake up! -Oh my gosh, what to do?

Is there anyone here?!

Jin Won! Jin Won!

Seo Jin Won's emails.

Received emails.

Do you want to delete it permanently? Yes

The person logged in from a different computer and deleted it?

But Cha Soo Yeon's emails were deleted on Cha Soo Yeon's computer personally.

That's right.

Cha Soo Yeon could've deleted the email from a different computer or cellphone, but

why did the person make Cha Soo Yeon delete the email on her own computer?

Legend's answers.

Are you sure you want to delete this file permanently? The file has been deleted.

The person did not come to delete the email,

she came to delete the actual file.

The real secret that someone wanted to hide..

it's the Legend's Answers file.

However, why did Cha Soo Yeon delete the file personally, but

Seo Jin Won's email was deleted from a different computer?

In Cha Soo Yeon's room, you said that you saw the girl student right?

Yes.

Seo Jin Won... is a boy student.

Do you think a girl student would be able to secretly go into a boy's room that easily?

She couldn't do anything but delete the emails.

Then, if we find that girl student, every secret would be solved.

I requested the IP address from the ISP used for deleting Seo Jin Won's email.

Detective Lee Tae Gyun will find out and call me soon. Then we will know who deleted the email.

Did you request it from the ISP?

Not by hacking?

Well, I thought some other stupid things would happen again.

Is your arm okay?

No. 1 Cyber Crime Squad of the National Police Agency, Team Leader Kwon Hyuk Joo?

Yes.

He is investigating the Nam Sang Won case.

Alright. I will call again.

Did some problem come up?

Uncle, this is not a problem that you need to be concerned about.

Do you have some artwork that you like?

It's not like if I have some things I like, I can keep it all.

I am always cautious.

You are not the successor of the Se Kang Group.

I know.

If you know, why do you keep making problems become bigger?

You mean the merger with Safe-Tech?

I only did it for the Se Kang Group.

These days, internet security is more important than the door of a safe.

We can't depend on outside companies for this important task anymore.

And the Safe-Tech vaccine program has been proven in this June 12 DDoS attack.

I think it will be a big help for Se Kang Group's internet security.

And at this time, we should check the internet security of headquarters.

Okay.

I will discuss it when I have a CEO meeting with the affiliates.

Thank you.

Father.

I have a car ready outside.

Keep in mind what I said.

I understand.

No matter what you do, you can't take my place.

If you don't want to be like your dead father,

I am saying for you to live calmly.

Alright?

That's right.

I am not interested stealing your place.

As you know, the vaccine program is important.

Of course.

If the vaccine program is success, then everything ends.

Please find out about Kwon Hyuk Joo, who is the Team Leader of the Cyber Crime Squad.

Got it.

There is no CCTV at all here...

Team Leader.

Oh, did you get it?

Yes. Young Jae Security Chief Ahn said hello to you.

"Hello?" Whatever...

You are certain right?

Hae Myung Resort.

Of course.

By the way, it was close, because they only keep these for a year.

They almost destroyed these.

Now, turn it on.

But are you sure?

Is Kim Woo Hyun really related to this case?

I will have to check from now on.

Now, May 16th. Turn on the CCTV.

Yes.

Check the car number.

34DU4035 and 15DA5894 Both of them.

Yes.

Huh? It's the car number you were talking about.

34DU4035

Is this man CEO Nam Sang Won?

Right.

Now, turn backward more.

It's really Lieutenant Kim Woo Hyun.

Now, we will go through the CCTVs of this night in detail.

Starting when?

Starting now.

Starting now. Start.

As you asked, I searched for the IP for the deleted email.

According to the telecommunication company, it was a smartphone.

Smartphone?

Yes. The number is 010-00700-0536.

The owner's name is Cha Soo Yeon.

19 years old, a student of Seong Youn High School.

Wait a minute. Can you tell me it again?

What did you say the name is?

Cha Soo Yeon. Are you sure?

Yes, that's right, Cha Soo Yeon.

Seo Jin Won, on his left hand he had a bandage.

Cha Soo Yeon, on her left hand she had a bandage.

Health Educator. Yoon Hye Kyeong.

Hi. I'm the cyber officer in charge of the Sung Yeon High case.

I have something I am curious about.

Student Seo Jin Won, hurt his left hand before dying. By any chance, do you know how he got hurt?

I heard that while sculpting in art class, he accidentally cut his hand.

Seo Jin Won!

The Art Teacher was suprised so she brought him here.

It wasn't even time for sculpting, but with the knife, I guess he was fooling around.

Student Cha Soo Yeon's cellphone number?

Yes, did you discover it?

No, in the dormitory there were no cellphones.

We are trying to find it as well.

Yes, I understand.

Investigator Lee. I have one more favor.

Please locate where Cha Soo Yeon's cellphone is.

Uhh, well tomorrow we have finals.

I just need to know one thing.

Why was Soo Yeon's hand hurt?

That...

Tell me.

I will keep a secret from the teachers.

She cut it herself.

Soo Yeon, do you have an English summary?

Soo Yeon, I asked if you had any summaries.

Soo Yeon.

I thought it was just stress.

Because of finals coming up.. I thought it was hard on her.

Seo Jin Won, Cha Soo Yeon,

before they died, both of them acted strangely.

Did you know that?

Be quiet. They have final exams tomorrow.

Are the exams the problem right now?!

Two kids have died.

What exactly happened to them?

How would I know?

Jin Won and Soo Yeon, they were both getting very stressed out because their grades were dropping.

That's probably why they did that.

Because they have stress would they do the same things to their hands and die in the same place?

This is not just an ordinary suicide.

There's definetly something to this!

You know something, right?

If I knew something, I would probably have already told the police!

You take care of the kids that leave the dormitory, right?

You take care of the kids that leave the dormitory, right?

The two kids died around 8, outside the dormitory.

If they were to leave at that time, then they would have to tell you where they were going and why.

The art room.

Pardon?

Before they died, both of them said that they were going to go to the art room.

They said that they left something in there.

According to the time, Director Nam got there 10 minutes earlier.

And Kim Woo Hyun arrived later.

Subtitles borught to you by Cyberghost Team @ viki.com

It ends here.

There isn't a camera by the 12th house.

Turn on another one.

Huh?

You said that Director Nam died in number 12 (resort house number).

Then, that would be the only place that we would have to look at.

Director Nam Sang Won did die in that one. But there isn't any evidence of Kim Woo Hyun going there.

We need to find out if Kim Woo Hyun went to the 12th one or if he went to another one.

I see.

This car is Nam Sang Won's, but it is passing by unit no.13.

Did you say he died in unit no.12?

Look for Kim Woo Hyun's car, too.

Yes.

Here, here.

Stop, stop.

Now next one.

Yes.

It's passing by unit no.14.

Good.

Forward it quickly.

Nam Sang Won's car is passing in front of unit no.15.

KIm Woo Hyun also.

Well, next one.

It's not in front of unit no.16.

Play the unit no.15 again.

Stop.

That night, Nam Sang Won and Kim Woo Hyun didn't go to unit no.12.

It was unit no.15.

Since we found Nam San Won in unit no.12,

we thought the two of them met there.

Wait, what is this?

32MEO5987?

Yes.

Why?

32MEO5987, a white sedan.

Do you know whose car that is?

Oh?

What is this?

Why? Do you know the car?

Hold on.

Why?

Why? What's wrong?

Case no. 2234.

32MEO5987

It's Shin Hyo Jeong's car.

Shin Hyo Jeong's car?

Nam Sang Won, Kim Woo Hyun,

and Shin Hyo Jeong were all together.

We traced the location of the Cha Soo Yeon's cellphone, which you asked for.

It was in Seong Youn High School. I will tell you where it is.

Someone has a secret

which is related to kids.

And the cellphone that was used to delete the secret

is in here.

Where would it be?

Kids got the same Legendary Answer sheet.

They hurt their hands, and came here before they died.

What would the reason be?

From this cellphone, someone sent an email to the kids.

The Legendary answer sheet

Have you heard that the teacher's computers were hacked a few days ago?

I stole the final answer sheet from the teachers' computers.

The attached file is the answer sheet.

You need the password for opening this file.

If you accept my request,

I will tell you the password.

But you shouldn't tell anyone about this.

If you want to start this game,

keep your student ID on the rooftop until tomorrow lunchtime.

Keep your midterm exam report card on the rooftop until tomorrow lunchtime.

If there is nothing on the rooftop,

then I'll assume that you rejected my offer and I'll give it to someone else.

Seo Jin Won's student ID, Cha Soo Yeon' s report card.

After they died, all of these were found on the rooftop.

I got your item on the rooftop.

Now you do me a favor.

It is very simple.

Hold a knife with your right hand.

Stab your left hand palm with it.

There should be blood.

If you can bear it more, it will end soon.

Why did they come here?

Kids...

didn't fall from the rooftop.

Someone put wax on the pillar.

Although kids tried to hold the window frame with their left hand, because their hands got hurt, they slipped.

Trying to get the password killed the kids.

This is...

a homicide.

The pillar outside the window, the wounded left hand,

the items on the rooftop.

Everything is...

planned.
