Unidentified dead bodies have been discovered in the yard of a house.
It's the serial killer couple, Jo Young Hoon and Ahn Yeo Jin.
Their execution has been confirmed before we found her remains,
so the government wants us to solve this case quickly.
Ahn Yeo Jin was the anonymous reporter who reported Jo's murders.
Do you really want to know how many more women...
I buried?
Stop fooling around.
If we want to delay Ahn Yeo Jin's execution,
we must find the son.
Is this really Ahn Yeo Jin's son?
I achieved my own peace...
19 times.
He just confessed he killed six more people than we know.
Do you have any last words?
I won.
Your illusion is over.
Yeo Jin belongs to me for good.
(Episode 13)
She cut out only the picture from the newspaper,
so I couldn't find the article.
He was two years old when he went missing,
so he must be 17 now.
This must be Si On's most recent look.
Team Manager Kang. I searched for Ahn's father, Ahn Sung Tae.
Ahn Sung Tae has a record of six years in prison...
for violence and attempted murder.
Even after he was released, he was frequently imprisoned.
Ahn Yeo Jin will never confess.
Jo Young Hoon is dead.
He can't harm your son anymore,
so tell me where Si On is.
Let's stop this insanity.
It is...
a great gift...
to be a parent in one's life.
But even at this moment,
there are people...
who are stamping on the gift.
Most parents also don't recognize the value of the gift.
Ahn Yeo Jin.
Tell me...
where Si On is.
I made up my mind 15 years ago.
It had nothing to do with my husband.
My decision was solely for Si On.
I'd like to respect your decision,
but I can't let someone die...
for the crimes she didn't commit.
This...
isn't your problem.
You have no idea.
I do.
I do know why you made that decision.
What kind of person your father was in the past.
You said this before.
"Why should little children..."
"suffer..."
"because of the sins we've committed?"
That was your own story.
Because you're aware of how terrible it is...
to live as an offender's child in this world.
You know how traumatic it is.
You sent Si On to a cleaner...
and safer place...
with no pain.
Because you wanted to keep him where he could be happy.
We don't have much time.
Where is Si On?
Ahn Yeo Jin.
Whatever the reason may be,
I won't let Si On lose the greatest present...
he could get in his life.
Team Manager Kang.
What would you do...
if Han Byul had to live...
as the son of a serial killer...
who had mutilated bodies?
My decision...
was the last present I could give to Si On.
This...
doesn't involve you.
No one can stop me.
After Si On was born, the only chance for Yeo Jin...
to get out of Jo Young Hoon's watch...
was when she had private lessons with students.
Yes. And most students who had been tutored by her...
had affluent backgrounds.
I will examine the families...
whose children had received lessons from her since 2005.
I will also check if they have any adopted children.
Come to think of it, Ahn Yeo Jin used to ask her mother...
to take her near the astronomical observatory when she was a child.
Even most of her paintings in Yeo Jin's cell...
had geometrical patterns and astronomical meanings as well.
This is a painting by a Spanish artist, Luis Ricardo Falero.
His favorite theme was the sky.
He mostly drew about myths and fairies.
One of the unique traits that his paintings show...
is the children-like smile of women in the paintings.
But this one is hugging the moon.
Team Manager Kang, it says here that Ahn Yeo Jin has taught...
children from three families in Bunjeong, Gyeonggi Province.
And one of these families had adopted a child in 2004.
Bunjeong, Gyeonggi Province?
There is an observatory near her mother's house.
According to the report, she had both love and hatred for her mother.
She must have thought that the safest place...
was near her mother's place.
Sun Woo.
Send me the address.
367, Hasoo 1-ro, Bunjeong-gu, Gyeonggi Province.
He was adopted to Go Yong Jin's family.
But something's strange.
Their son's name is Richard Ahn.
Even though his mom's name is Hwang Seo Kyung.
Richard Ahn?
He has a separate address registered under his name.
Send the address to Hyun Jun.
Team Manager Kang.
"The Cello Prodigy, Richard Ahn".
"Everyone is Praising and Clapping for Him."
Sir.
We have found her son.
No one...
has given me orders to suspend her execution.
Before I receive an official document about the suspension,
I have the responsibility to carry out the law.
My agents have gone to get her son.
We have also sent a request to the Ministry of Justice.
Yeo Jin did not kill her own son.
If you only wait a little longer,
you can soon meet Si On.
Will we be able to make it on time?
We should at least try.
(13 minutes before Ahn Yeo Jin's execution)
We cannot wait any longer.
Wait here.
Yes, sir.
Don't overdo yourself.
If, as a parent, you could give your child...
a life you couldn't even dream of,
you would have probably done the same thing.
Ahn Yeo Jin.
If Si On finds out about you,
would he be able to understand this situation?
He doesn't need to know who I am.
That's the only thing I want.
I will save your life first.
My life...
has ended...
the day I met Jo Young Hoon.
This is the one.
Team Manager Kang, we've arrived.
No, we couldn't contact him.
- Go Young Jin and his wife... - Hello?
won't answer their phones.
Is anyone home?
Time is up.
We need to go in.
Wait.
Kim Hyun Jun, break the doors if you have to.
I will take full responsibility.
Team Manager Kang Ki Hyung!
Sir,
it won't take long.
We can prove it.
Wait here, and don't come outside.
We're from NCI.
Are you Go Young Jin?
Yes.
You didn't answer the phone, so we had to come here.
We'd like to ask you a few things about your son.
What about him?
Do you...
happen to know a child named Si On?
Who is that?
Did something happen to a child named Si On?
Team Manager Kang, I think we found him.
We found your son.
This is my decision.
Please...
don't make him the last victim of Jo Young Hoon.
Team Manager Kang.
Please...
let me go.
Ha Sun Woo.
That wasn't the boy we were looking for.
I must have made a mistake.
I'm so sorry.
We must have come to the wrong address.
I'm sorry to have caused you inconvenience.
I'm sorry.
Detective.
Thank you.
I want your face to be the last thing I see...
before I go.
Would that be all right?
"The best and most beautiful things in the world..."
"cannot be seen or even touched."
"They must be felt with the heart."
Helen Keller.
(Mo Ji Eun)
You're mine, starting today.
Who do you think you are to say that?
It's up to me.
Day one starts today.
(Mo Ji Eun)
(2017 Honor Roll Scholarship Ceremony)
2017 Cheonju Youth Center scholarship receiver...
Park Ji Ye, please come up to the stage.
The above student received an outstanding grade...
and became a good example to other students with good conduct.
So this certificate is given.
Congratulations once again to Park Ji Ye.
The next up is...
- Hyun Jun. - The Cheonju Youth Center...
scholarship for students with good volunteer experiences.
Kim Min Jung, please come up to the stage.
Is that Sang Ho?
He used to be so smart.
He's ruined now.
How did you make it here? You're so busy.
You know lawyers aren't doing well nowadays.
I can't even afford the rent, so I have to move out.
Hurry up.
Kim Hyun Jun.
Detective Tae.
Let's not make a scene.
Wait.
What's going on?
Kim Hyun Jun, you're under arrest for murdering Kang Ho Young.
Hold on.
What are you talking about?
Let's not make a scene here and leave.
Take him.
- Detective. - Be quiet.
Detective Tae.
Sorry.
(NCI)
(Nana Hwang)
(Lee Han)
(Yoo Min Young)
(Ha Sun Woo)
(Kim Hyun Jun)
I'll be lonely for a while.
Someone will fill in soon.
Consider this...
as what's best for you and the team.
I know you've thought this through enough to make this decision.
It also took me a while to make this decision.
Don't mind it.
Sure.
So you're going to take a rest for a while?
Yes.
I'm planning to spend time with Han Byul...
and pay a visit to my mother.
Let's go out.
Spend some time with us.
It's been a while since we had dinner with the whole team.
Let's go out for dinner together.
But why did the chief director tell us to stay?
I'm not sure.
Is he going to give us a compensation to appreciate...
what we've done?
Or a surprise dinner?
Hyun Jun should be here to enjoy this.
Why did he have to go to his hometown now?
I wonder if he's arrived.
By the way,
I've never been to Cheonju. What's it like?
Cheonju?
It's a romantic city.
How about we all head to Cheonju...
since we're on the topic?
Where's Min Young?
She went to the press room.
Is everything all right?
I want to treat you to dinner.
And Team Manager Kang has something to tell you.
Sorry to interrupt. You must see this.
We have some breaking news.
As the identity of the murdered man who was found...
near Cheonju Dam in Cheonju-si, Gyungnam, is discovered,
the main suspect has been arrested.
We'll talk to reporter Han Yeo Ul in Cheonju Police Station.
Hyun Jun got arrested as a murder suspect.
Through the analysis...
- How did this happen? - of the surveillance camera,
they've found crucial evidence that Mr. Kim is the culprit.
Suspect Mr. Kim...
kept in touch with victim Kang for many years until recently...
and are both known to be from the same youth center.
Kang Ho Young, 32 years old.
The cause of death is skull fracture by a blunt weapon.
He was found dead in the forest near Cheonju Dam three days ago.
When the body was found, it was decayed too much to identify.
And mortem examination assumes he died about 20 days ago.
According to the police investigation,
Hyun Jun's fingerprints and Kang's fingerprints and blood were...
both found...
in Cheonju Youth Center gym, the suspected murder site.
They also secured a surveillance camera record...
of Hyun Jun walking out from the site.
Hyun Jun is also the last person he called on the day of the murder.
And it's confirmed...
that Hyun Jun was at the site at the estimated time of murder.
(Kang Ho Young)
Let me answer this.
What's the criminal intent?
Hyun Jun has no reason to do so.
I know. Why would Hyun Jun do that?
And they are childhood friends.
Ha Sun Woo.
Yes.
Tell me what's on your mind.
Hyun Jun...
has been tracing the Nadeul River murder case.
Kang Ho Young was one of the Nadeul River murder case suspects...
14 years ago along with Go Young Min, who recently died.
Hyun Jun was also a suspect.
Then...
is what he said before true?
I was one of the suspects.
This case of Kang Ho Young and Nadeul River murder case...
must be related.
So you're saying...
Kang Ho Young called you first to meet up,
but he didn't show up?
Then how would you explain this?
(Call History)
Do you think I killed Ho Young...
to close the Nadeul River murder case?
Hey.
What I think isn't important now.
This...
is what's important right now.
Even from the past,
you always thought I was the murderer of that case.
So what?
The Nadeul River murder case...
was your first murder case...
after you were assigned to the Violent Crimes Unit.
You've been looking for the evidence of the past crime...
due to the guilt regarding the unresolved victim's sorrow.
And your obsession...
only grew bigger.
Be quiet.
If I'm the criminal,
do you think I'd be so foolish to leave my fingerprints...
and get myself caught by the surveillance camera?
Think about it.
Due to your obsession...
You could be making things up.
Hey.
Don't try to fool around with me.
Do you really want to solve the Nadeul River Case?
Shut your mouth!
Find the real culprit who killed Ho Young.
That's what you need to do.
Hey.
Don't fool around with me.
You got out in the past,
but you can't get out this time.
You scumbag.
What are you doing without reporting to me?
And what have you been doing?
I told you to report to me when something happens!
It happened when you were away on a business trip.
I'm sorry.
Both of you, get out.
Get out, scumbag!
Hyun Jun.
What's this about?
Sun Woo.
Thanks.
When I was young,
I used to visit Cheonju every vacation.
My grandmother lived there.
Were you investigating...
the Nadeul River incident as well?
It was me.
I found the dead body first.
What?
- You stole this card, didn't you? - I didn't.
Is this what your mom taught you to do?
Go, and get your mother.
It's not like that. I was asked to run an errand...
for my brother's friends there.
You probably stole it. I will call the police.
- I... - She didn't do it.
I saw everything.
What she said is true.
You can take my umbrella. You're all wet.
It's all right. Someone's coming to fetch me.
You should use this. I don't like to be in debt.
What happened to the missing girl? Could something bad have happened?
She's only in middle school. Don't say that.
Anything can happen in the dangerous world we live in today.
The mere thought of it scares me.
Kang Ho Young told you that he had something to show you?
Yes.
Ho Young could have had...
some evidence of the incident that happened in the past.
Aren't you trying to fit things into the situation...
due to your obsession with the incident?
We need to move away.
Yes?
You can't tell anyone.
Do you understand me?
Yes.
It's all right. Study hard.
All right?
Okay. Goodbye.
Are you just letting him go?
We have suspects everywhere.
We don't have time to waste on children.
His alibi on the day of the incident is unclear.
Didn't you see him change his words when we cornered him?
Gosh.
He's just 11 years old. He barely started studying.
Don't waste your time on him and find other suspects.
Hello.
I'm Oh Jeong Taek. We spoke on the phone earlier.
I'm Kang Ki Hyung.
Where is Hyun Jun?
He's in the interrogation room.
I expect you to have taken into account the consequences...
for having arrested our agent without informing us beforehand.
If this was an investigation held without circumstantial evidence,
I am not going to let this slide.
And you also need to take responsibility for the fact...
that you informed the media about the arrest first.
We had found definite evidence.
He was investigating the Nadeul River Case.
It's our belief...
that someone involved in the case is trying to frame him.
Do you agree on the fact...
that the culprit of the Nadeul River case killed Kang Ho Young?
What if a profile,
that NCI has so much trust in, indicates one suspect,
and you are the one who proved it?
Don't you remember the profile?
It's nice to meet you. To figure out serial killers,
you need to consider their age,
background information, and...
- Thank you. - Thank you.
Thank you.
Excuse me, but this...
is the case I'm investigating on.
The biggest problem here is his age.
I...
had suspected Kim Hyun Jun as the culprit and watched him...
because of what Team Manager Kang had profiled for me.
Considering the place where the bodies were abandoned,
the culprit must be familiar with the region.
According to forensics, the Nadeul River murder...
and the murder of Kang Ho Young were both caused by strangling.
The culprit must be smart enough to hide the crime...
and be familiar with the police investigation process.
He might have committed crimes before,
or he could work in the law enforcement sector.
Culprits of cases that have been unsolved for a long time...
tend to be both anxious and confident.
So it's likely for them to visit the crime scene or the victims.
Some show interest in the investigation...
and even participate.
Do you know...
who visits the victim's grave every time he visits Cheonju?
And...
do you know who contacted our police station frequently,
showing interest in the Nadeul River Case?
He knew both Mo Ji Eun, the victim who died 14 years ago,
and Kang Ho Young,
the recent victim.
And he was the last person that they contacted before they died.
According to my profile, everything...
leads to one person.
Kim Hyun Jun.
Do you think this is a coincidence?
Detective, you have made a critical mistake...
in your profile.
You said that the victim had either committed a crime before...
or worked in the law enforcement sector.
But Hyun Jun had nothing to do with that when the incident had happened.
Yes, he has no criminal records.
But before the incident,
Kim Hyun Jun...
came to the police station often for fighting incidents.
So he knew very well about the legal procedures.
How about his age?
He was only 17 then.
His age?
You told me...
the culprit's age is the most difficult to estimate.
"Just because the age doesn't match,"
"we shouldn't ignore a suspect so easily."
Do you remember saying that?
Just as Sun Woo said,
I'm sure he fell into a trap.
Maybe...
the suspect already knew that Detective Tae...
was already suspicious of Hyun Jun.
Kang Ho Young probably tried to tell Hyun Jun...
what had happened in the past.
Someone must have kept watch on Kang Ho Young...
and probably set up a plan after realizing...
that he's meeting Hyun Jun.
And the time they found the body is also suspicious.
It's as if they knew Hyun Jun was going to attend the center's event.
The body was found at such a coincidental time.
But why did Kang Ho Young choose Hyun Jun...
over all the police officers nearby?
(Nana Hwang)
What happened with Hyun Jun?
How's the situation? Is he okay?
An arrest warrant was issued for him,
so we only have two days.
As you requested,
I did a background check on all of Kang Ho Young's acquaintances.
But I didn't find anyone...
who did something suspicious on the day of the incident.
I'll see if there has been any...
similar cases to the Nadeul River case and get back to you.
I'll go see Hyun Jun.
You two go to where the body was found, and look for any traces.
There must be a reason why the body was abandoned there.
Yes, sir.
Things aren't looking good.
Did anyone know that you were going...
to meet Kang Ho Young?
As far as I know,
no.
Why did Kang Ho Young...
ask to meet you there?
Do you have any idea what he wanted to show you?
I don't know.
Is there anything...
I should know about the Nadeul River Case...
that's not in the case file?
Let me rephrase.
What else...
do you know about this case?
Tell me.
Are you...
profiling me right now?
You have to help me...
for me to help you.
We trust you.
Everyone in the team and I will do our best to help you.
If you remember anything, even if it's something small,
you should tell me first.
If there is anything I need to know, tell me.
It's not me he was after.
I think he's after not only the team manager,
but our entire team.
Give me a detailed report on the youth center...
and on Kim Hyun Jun too.
Sorry?
What do you specifically want to know about Hyun Jun?
From his past to the present,
his acquaintances and what he did in the past,
look into everything related to Kim Hyun Jun.
It's not me he was after.
I think he's after not only the team manager,
but our entire team.
Give me a detailed report on the youth center...
and on Kim Hyun Jun too.
Sorry?
What do you specifically want to know about Hyun Jun?
From his past to the present,
his acquaintances and what he did in the past,
look into everything related to Kim Hyun Jun.
Okay. I'll call you as soon as I find something.
I think he's hiding something.
If he's really acting according to someone else's plan,
it must be someone who knows very well about us...
or what Hyun Jun does throughout the day.
Do you think this is related to the Reaper?
First of all,
it's important to clear Hyun Jun of murder charges.
We have to think about all the possibilities when approaching this.
Someone publicized the forgotten Nadeul River Case.
It's possible that an outsider planned all this...
to uncover the truth from the past.
Then do you have someone in mind?
Not yet.
But I'm sure that whoever it is,
we have to find out what Kim Hyun Jun knows...
about the Nadeul River Case.
Only then will we know for sure who's behind this...
and why he wants to frame Hyun Jun for the murder.
The body is severely decomposed to the point of being unrecognizable.
Do you think the body was abandoned right after the murder?
No.
The body was probably abandoned after the 26th.
Then the killer kept the body for more than two weeks?
Yes. He probably wanted to avoid the discharge period.
During the summer,
Cheonju Dam discharges water on set dates to control water levels.
They announce their discharge plans in advance.
Recently, they've been discharging water every 15 days.
The killer abandoned the body in a ditch...
so that it wouldn't be washed away after the discharge.
At first, it seems as if he left the body in an inconspicuous place,
but in reality, he planned everything so that the body...
would be found within a certain period.
You're right. He probably knew exactly when...
the manager checks water levels after the discharge.
Every year, a flock of migratory birds come to Nadeul River...
and create a beautiful scene at this time of the year.
This is the perfect place to see it.
But what does that have to do with this case?
You always see articles on the newspaper.
This is where the festival happens,
and you can photograph the birds too.
I'm sure that someone took a photo here.
I looked into the center.
But there were no management problems until now.
It received several appreciation plaques from the government too.
I'm gathering a list of employees who worked there 14 years ago.
But it was so long ago,
and they once lost all their records in a fire.
So it's not easy.
Fire?
Yes. There's a record of a fire that occurred in 2004.
Look into that.
What caused the fire, and who were involved?
Okay.
(Appreciation plaque)
No one passes through this place because of the construction.
Why did they agree to meet here?
(Cheonju Youth Center)
The center is familiar to the two of them.
If the place wasn't used for a while,
they probably considered it safe.
This place is optimal...
to hide something.
The thing Kang Ho Young hid.
The thing he wanted to show Kim Hyun Jun after 14 years.
What could it be?
The killer used the shortest path...
that's completely hidden from others...
to move the body.
(48GU2354)
(Garden Pond)
Why did you come here?
I told you not to contact me or come here for the time being!
Did you...
really kill Kang Ho Young?
The parents helped us tremendously...
to help this center find a home here.
But I had no idea I'd have to meet them again...
for something like this.
We have a couple questions concerning the past incident.
What does that incident have to do with this?
That's in the past.
Stop bringing up past sorrows.
We've suffered enough because of that incident.
Were there any problems in the center at the time?
It's already been concluded...
that no one in this center...
had anything to do with that case.
Why do you always come to the center when something like this happens,
and create a huge fuss?
Was Kang Ho Young really murdered in this center?
That's something we've confirmed.
I don't believe that.
My goodness.
I don't have anything more to say, so please be on your way.
The head of the center is hiding something.
Yes, he's overly defensive about the past incident.
Does that mean he's somehow involved in it?
I'm afraid something...
happened in the center before Mo Ji Eun died.
I looked into the fire I mentioned earlier.
- Go ahead. - In February 2004,
6 months after the Nadeul River incident,
there was a fire at the center which was suspected to be arson.
I found someone suspicious in the list of suspects...
identified back then.
He's Choi Sang Woo, currently 32-years-old.
He was 18 in 2004 at the time of the fire.
Choi Sang Woo went to the center back then.
But around the time the fire occurred,
his sister Choi Hee Jin committed suicide.
Because of that Choi Sang Woo became a prime suspect for the fire.
There's a witness statement saying that when the police took him in,
he threatened to kill everyone at the center and caused a scene.
(Statement)
Arsonists are likely to have an impulse control disorder...
where they feel pleasure in causing fires.
There's a high chance for a serial arsonist...
to turn into a serial killer,
but he's far from the profile we have for Kang Ho Young's murder.
Serial arsonists do not have this long incubation periods.
If he continued to live in the same area,
he must have had caused more fires.
In this case, it's more likely that the arson's caused by rage...
and hatred rather than pleasure.
Choi Sang Woo's been involved in several minor battery cases.
He was in and out of juvenile correction centers...
for security issues too.
He must have known better than anyone else...
about the center's CCTV system.
If he held a grudge against the center and caused the fire,
he might be related to the Nadeul River Case.
If he tried to publicize an unresolved case from the past,
he must already have enough of a motive for murder.
Can we see a photo of his sister who committed suicide?
Of course. Just a moment.
I sent it over.
Choi Sang Woo's sister, Choi Hee Jin,
went to the same center as Mo Ji Eun.
I heard a boy and girl were alone.
Really?
That's ridiculous.
What if the girls...
were sexually molested in the center?
Maybe that was why Choi Hee Jin committed suicide?
What if Mo Ji Eun knew something,
and she was murdered to make sure the secret never got out?
Someone suggested that in the past,
so all the girls at the center were questioned.
But they didn't find anything suspicious.
Go Young Min was pointed as a suspect precisely because...
he had a history of sexual offense.
Considering how the youth centers are so enclosed,
we can't rule out the possibility that the investigation was hushed.
What if Choi Hee Jin committed suicide because...
she was sexually molested or abused at the center...
there may be more than one victim.
Mo Ji Eun could have been one of the victims too.
I have to stop by somewhere.
I'll call you when I get back.
Look more into what caused Choi Hee Jin to commit suicide.
I want you look into the list of suspects from the past case.
- Min Young, you'll come with me. - Sure.
- Hey. - What?
- Did you hear that? - What?
They were together at the training center.
- The training center? - Yes.
What?
That's ridiculous. I'm getting goosebumps.
I know, right?
Hi.
What if Choi Hee Jin committed suicide because...
she was sexually molested or abused at the center...
there may be more than one victim.
Mo Ji Eun could have been one of the victims too.
He was a model student at school.
He got good grades as well.
He won many awards since he was young...
in creativity competitions or math competitions.
Are you Choi Sang Woo?
We're from NCI.
We have a few questions to ask related to...
the youth center arson in 2004.
I have nothing to say.
The case closed a long time ago.
Did you set the center...
on fire?
I told you it's not me.
As you know,
we're not trying to keep you accountable for it.
We're investigating past incidents at the center...
relating to the Nadeul river murder case.
I ask for your cooperation.
Nothing happened.
Then...
can I ask why your sister committed suicide?
Please tell us.
Does your sister's suicide have something to do with the center?
I said no.
I have nothing more to say. Leave.
Let me ask you one more question.
Did your sister go through a bad experience at the center?
You have no idea.
Leave. I have nothing to say.
What are you trying to hide now?
I said leave!
Do you think many people died due to that incident?
- You... - Fine. All right.
His personal relation's too unstable...
to look people in the eyes.
He shows signs of rapid...
personality changes from depression to rage.
Piles of medicine.
Evident trace of self-injury on his wrist.
Unpacked packages prove...
his compulsive consumption pattern.
It's the typical signs of BPD.
BPD patients show a weak attitude,
but when they're under pressure,
they instantly become impulsive.
- You... - Fine. All right.
Many BPD patients are caused...
by losing the object they loved, an abuse in the childhood,
or a sexual trauma.
It must be the same for Choi Sang Woo as well.
But most BPD patients...
have a fear that they would be abandoned.
He's closer to the type with strong egos.
He doesn't fit into the profile that he started the fire...
due to his sister's death.
- Hello. - Team Manager Kang.
I think I know why Choi Hee Jin committed suicide.
I was going through her high school records,
and I found school violence measure minutes...
in 2004 the year she committed suicide.
Her name was on there.
Aside from the problem at the center,
it seems she committed suicide...
due to school violence.
What should we do at the festival?
I'm not sure.
Actually, it's my first time going to a festival.
Sun Woo,
let's just go to the festival now.
- Team Manager Kang. - There's a high possibility...
that Choi Sang Woo didn't set the fire because of his sister.
We need to find out what Choi Sang Woo went through...
at the center in the past.
I'm not the one. I didn't do it.
Dae Soo. Dae Soo.
Dae Soo. Wait. Dae Soo.
Team Manager Kang. Hyun Jun changed his testimony.
Did you kill Kang Ho Young...
to close the case for good?
We must stop them.
Team Manager Kang has a plan.
Are you saying there's an accomplice?
Hurry up and find Hyun Jun!
He's not aware that we know who he is.
I found his location.
He's after the whole team.
