Where did this jerk go?
Park Kwang Ho!
What?
Wait. What's going on?
It can't be...
Am I...
back in the past?
Wait.
How did I get back? I didn't even catch that jerk.
What's going on?
Wait.
What happened to him?
No!
Where is he?
Did he disappear again?
Like he did before? Did he...
return to the past?
If this is the past...
Yeon Sook!
(Forbidden City)
My house is still here.
Yeon Sook. Yeon Sook!
- Yeon Sook. - Kwang Ho?
Is it really you?
Yeon Sook.
Why did you come back so late?
I've been waiting for you for so long.
Where have you been?
I really thought you were dead.
You are alive.
Yeon Sook.
I know I'm late.
Yeon Sook.
I'm sorry.
I'm so sorry, Yeon Sook.
(Episode 13)
What happened? Where have you been?
Yeon Sook, that is...
What are you wearing?
When is our daughter due?
What? How did you know it was a daughter?
I...
You didn't even know I had a baby.
You went missing before I got a chance to tell you.
It's been over five months since you went missing.
Five months?
So time passed at the same speed.
What do you mean?
Yeon Sook.
You asked me where I have been.
Will you believe whatever I say?
Where have you been?
Do you want me to believe this?
I know it'll be difficult.
I didn't believe it at first.
I once asked you about a person without any records.
He doesn't even have his fingerprints registered.
There is no record of him whatsoever.
What does he have to hide?
That was Kwang Ho.
The thing he wanted to hide was the fact that he came from the past.
Let's stop talking about this nonsense.
The whistle.
I know your mother gave it to you.
I heard it from Kwang Ho.
Yeon Sook,
your mother,
gave it to Kwang Ho as a gift.
It's real?
Corporal Park is...
In the tunnel,
he hit me in the back of my head right here.
- Oh, my. - Then I went straight to 2017.
- So I went to the police station. - The year 2017?
- He hit me with a rock. - Were you all right?
What should I have done? So I went to the police station.
I lost the whistle there.
The telephones there...
- don't have lines connected. - No lines?
- That doesn't make sense. - Everything.
It's this small.
It's the size of my palm.
So this...
I went to the station, but there were new faces.
So,
you were in the year 2017,
in the future?
You don't believe me.
So you knew it was a daughter.
And I gave this whistle...
to my daughter?
I wouldn't believe my own story too.
No one would. I sound crazy.
Then,
did you meet our daughter?
What?
Of course, I met her.
Yeon Sook. I could recognize her because of this whistle.
This whistle saved our daughter's life.
Also, she grew up to be a beautiful woman.
She's kind.
I mean people in the future would say she's kind.
Also, she takes after you.
Her name is Yeon Ho.
- Yeon Ho? - You put together...
my name and your name.
Isn't that old-fashioned?
It's a pretty name.
I'd be an old woman by then.
Did you meet me too?
What?
What is it?
I got really old, right?
No.
You were as beautiful as now, Yeon Sook.
Is that what's important?
You almost died.
I'm alive thanks to you, Corporal Park.
Look how bruised you are.
Think of yourself before you think about Jung Ho Young!
Hey.
Why are you...
wearing this necklace?
Who are you? Answer me!
You know something...
about that whistle, don't you?
What?
When you saved me, you saw that whistle and asked me who I was.
No, I didn't. You must've heard me wrong.
I'm sure you said...
I said I didn't. Good night.
(Corporal Park)
This phone is turned off. You'll be directed to the voice mail.
Please leave a message after the beep.
How did I come back here?
Is there a required condition?
Don't go.
Don't leave me, Kwang Ho.
Don't go.
I'm right here, Yeon Sook.
I'm glad.
I'm so glad to be back, Yeon Sook.
(Hwayang Police Station)
Where is Sung Shik? Hey.
What are you questioning your colleagues for?
That's not it. There was something I should've reported to you.
Among the seven murders Jung Ho Young committed...
No, you fool.
Why are you still investigating on a closed case?
The prosecution closed the case.
It didn't seem like one person killed all those people.
It may have been done by more than one person...
So? Who is the culprit?
You must've found it out after all that fuss yesterday.
- I haven't found it out. - Goodness.
Sung Shik.
Please stop.
Do you hear me?
You should all stop too!
You fools.
My goodness.
I knew this would happen.
I think Professor Shin is wrong about this.
The culprit can't be someone from the police.
Don't add oil to the fire.
I'm just upset.
We're so close, but we keep failing to catch this person.
("A Dead Body Found in Hwayang")
(Witness Jung Ho Young)
Chief.
These are the only clues we have.
Let's take a look at every incomer of 2016...
who meets the conditions.
Lieutenant Kim.
Let's do that. Tae Hee.
Hey. Hello?
Hello?
Can anyone hear me?
Stop it already.
I'm not even drunk now. Should I give you all a good yell?
He's right. It wouldn't have taken 30 years if it was an easy case.
Let's do this, Lieutenant Kim. We caught Jung Ho Young after all.
I think we can solve this case in the end. I can smell it.
Everyone here knows you can smell like a dog, Tae Hee.
Let's do it.
Yes. That's what I was saying.
Are you one of us now, not a guest?
Things are peaceful in a long time, and Kwang Ho isn't here.
Yes, Professor Shin.
Did Corporal Park come to work?
You mean Kwang Ho? No, not yet.
He's not answering his phone,
and I don't think he came home last night.
What are you talking about?
I'm saying Corporal Park might have disappeared.
Kwang Ho disappeared?
What are you talking about?
This phone is turned off. You'll be directed to...
His phone is still turned off.
When was the last time you saw him?
Weren't you with him?
Chief. What are we going to do now?
(Yoo Jae Il)
(Moon Hyung Pyo)
We should meet them.
Let's go, Kwang Ho.
Let's go.
Go ahead.
That was the last time I saw him.
That means no one has talked to him since then.
Trace the location of his cellphone,
- and check the call history. - What?
He doesn't have a place to go here.
He suddenly disappeared 30 years ago as well.
Something might have happened to him.
Let's report him as a missing person and call for backup.
You know we can't do that.
We have to find him on our own.
Goodness.
(Hwayang University)
Who would have thought you were the cop chasing me in the tunnel?
You and I have quite an interesting connection. Don't you think?
What? You find this interesting? Is this interesting to you?
There is no way...
he knows about this.
This is what Jung Ho Young saw during the visit.
He committed a suicide...
because Professor Mok visited him.
There must be DNA of the victim on this.
I can arrest him right away if this was the year 2017.
Yeon Sook.
Do you have anything I can use as an evidence bag?
An evidence bag?
Yes. I think a plastic bag will do.
You're being so careful with it. What is it?
The ultimate proof to catch the culprit.
Really? Then can you catch him now?
No, I can't do anything with this here.
We'll be able to get his blood type at most.
But in the future, we can catch him for sure with this fountain pen.
We need to preserve this until...
the DNA technology is developed.
I'll be back soon.
Aren't you going to eat?
I don't have the time, Yeon Sook.
In the future, no one knows he's the culprit.
I need to catch him fast, so that no more people get hurt.
I'll be right back.
You won't disappear again, right?
I won't. Don't worry.
And if something happens, call me on my cell phone.
Cell phone?
Right. Just a second.
Wait, why isn't it here?
Right. It won't work here.
I'll find public phones and call often.
I'll be back soon.
(Hwayang Police Station)
(Voluntary reporting period for weaponry)
I don't recognize anyone.
As Sung Shik said, the investigation team must have been disbanded.
The records will have been burnt.
No.
No one will believe that Mok Jin Woo is the culprit now.
I need to find evidence first.
You.
I need to find evidence first.
You.
How are you here?
- Park Kwang Ho? - Reporter Oh.
I heard you were dead.
You were alive?
Yes, I was.
By the way, I need your help. Come here.
How can you be alive?
What? You know who the culprit is?
Lower your voice.
But I don't have enough evidence.
That being said, you need to help me find someone.
There's a survivor in this case.
- A survivor? - Yes.
It's the fifth victim, Kim Young Ja.
The criminal thinks that she's dead.
If we find her, we can arrest him.
Oh, my. There was a survivor?
But why are you asking me? I'm not a detective.
Take Chief Oh and Sung Shik with you.
Right. Sung Shik has been sent to Gangwon Province.
That's what I'm saying. I can't bring him here to help.
Can you?
You jerk.
I'll help you write an exclusive if we get him.
- An exclusive? - Yes.
Imagine your article taking a whole page of the newspaper.
Let me think.
You are poking around again.
- Let's go. - Let's go.
I told her to go after graduation, but she left for Seoul anyway.
Where in Seoul is she?
She's at her uncle's.
She's working at a factory as a bookkeeper.
Can we get the address?
We are not going now, are we?
We don't have time. We need to go.
What now?
I'll pay for the ride. Just follow me.
I don't even have to say anything.
I like it. Let's go.
You disgust me.
(Hwayang Police Station)
(Call history)
The last time he called was 9:11pm.
But it was a burn phone.
- A burn phone? - Yes.
And it was turned off at 10:07pm.
It was near Hwayang Base Station.
It must be near the parameter.
This means he disappeared after getting a phone call.
- Chief, we should go there first. - All right.
Sun Jae and I...
will see if there's a place he might go near the base station.
Tae Hee and Min Ha,
you should check all the CCTV between the police station...
and the base station.
And before we know for sure,
don't tell anyone that Kwang Ho has gone missing.
- Yes, sir. - Yes, sir.
Let's go find him.
- Yes, sir. - I'll help.
You will?
Chief,
she knows who he is.
- What? - The chief knows too?
How does he know?
He worked with Kwang Ho 30 years ago.
What?
It's all right. He knows.
That's why you called him "sir".
There are so many surprises today.
So...
you know now, Professor Shin.
I do.
I have so many questions.
And he's gone.
Are you Kim Young Ja?
Who are you?
I'm the police.
Wait.
Young Ja.
It's not your fault.
Why do you have to hide?
He's the bad guy.
Young Ja, are you listening?
Young Ja, are you listening? Are you?
Other people don't think like that.
Hey, why are you acting like that?
You can simply point him out.
Be quiet.
I just meant...
If I testify, will anything change?
It will. Everything will change.
We can catch him right away with your word.
Otherwise, more women will get hurt.
Young Ja, please help me.
What does that have to do with me?
Just leave.
Young Ja. Young Ja!
Hey, just help us out once.
That's not too hard. Hey!
What do we do now?
We'll wait until she changes her mind.
You should go first. I need to go somewhere.
What?
Where are you going?
He hasn't changed one bit.
(Last location)
If it's near here, it could be...
Chief,
it can't be.
He said he couldn't do it no matter how hard he tried.
- Tae Hee. - Chief,
- his tracks seem strange. - Why?
He came out of the police station, went to the hospital and took a cab.
A cab?
Okay. Meet the driver first...
and go back to the station. All right.
He came out of the police station, went to Hwayang University Hospital,
and took a cab there.
Hwayang University?
Why on earth did he go there?
Let's head back to Seoul for now.
It might be better off if he had returned to the past.
What do you mean by returning to the past?
What on earth is that supposed to mean?
He ended up here while chasing the suspect from 30 years ago...
in this tunnel.
Kwang Ho believed he would be able to go back if he solves the case.
He believed that if he got back, Yeon Sook wouldn't have to die,
and Professor Shin wouldn't have to spend a lonely childhood.
Like Chief said,
it would be better off if he had really gone back through the tunnel.
If not...
(Hangang Cruise Ship Port Opening Ceremony)
Hey. Yeon Sook.
(Hangang Cruise Ship Port Opening Ceremony)
Did you tell me to come suddenly because of this cruise ship?
I wasn't able to keep my promise on your birthday.
Tickets for three, please.
There're three people. Yeon Ho's here with us as well.
Isn't that right, Yeon Sook?
Don't be silly, Kwang Ho.
Thank you.
Let's get on, Yeon Sook.
You too, Yeon Ho.
Let's go.
Seoul's so beautiful.
You're right. It's more beautiful since it's the three of us.
I haven't been able to do anything for Yeon Ho.
You can start now. You have plenty of time.
Your belly's gotten so big.
Everyone. Teddy bears are loved by all boys and girls.
Buy a teddy bear for your children.
- How much is this one? - That's one dollar.
Sir, how much is this one?
This one's two dollars.
- Two dollars? - Yes.
Yeon Ho. Do you like it?
I'm going to be a good Dad from now on.
All right?
Don't forget that, Yeon Ho.
My goodness.
Since we're in Seoul, let's eat something delicious.
Whatever you want.
Let's eat something expensive.
What?
Something expensive? Why not? Let's go.
This is really nice.
(Forbidden City)
Thank you.
You chose here again over somewhere expensive?
I'm going to eat something expensive after I'm finished here.
When you went missing,
I wanted to eat strawberries so much.
Strawberries?
Yes.
I felt so shameless.
I didn't know whether you were dead or alive.
It must've been so hard for you being on your own.
Forgive me, Yeon Sook.
I bought our Yeon Ho dumplings from this restaurant.
This restaurant is still here 30 years later.
- Really? - Yes.
I can't wait to meet our baby.
It's a good thing I didn't tell her who I was.
If she had found out, it would have been difficult for her.
What?
It's nothing. Go ahead and eat.
I'll pay for him. Let's go.
What? Why would you pay for me?
Hey, why would you pay for me?
(Sunhwa Boutique)
Yeon Ho.
Eat slowly and enjoy the food.
You too, Mom.
(Sunhwa Boutique)
Mom.
(Hwayang Police Station)
(Kwang Ho's hourly whereabouts)
(8:15pm: Left Hwayang Police Station)
(8:43pm: Entered Hwayang University Hospital)
(Police Station CCTV, Hwayang University Hospital CCTV)
Why would he have gone to Hwayang University Hospital?
There's no one he knows there other than Professor Mok.
Did you get any information? Where was he headed?
The driver said he got off in front of the tunnel.
Hey! You forgot your change.
The tunnel.
We lost him from there.
We checked the footage on the CCTVs...
and there was no trace of him getting back on a cab or leaving.
He couldn't have vanished into thin air. Where could he have gone?
I'm sure he's gone back.
If he had gone back, he wouldn't have left without saying goodbye.
With Professor Shin here, he wouldn't have left like this.
He left without notice 30 years ago as well.
We all thought he was dead, but he was here all along.
It's no different this time.
I'm sure he returned to the past through that tunnel.
It's a shame we didn't get to say goodbye, but it's better this way.
He should have returned much earlier.
Let's just focus on catching the culprit now.
We never know when another incident will...
Sun Jae, where are you going?
Sun Jae.
Corporal Park.
Can I see the CCTV footage from last night of Serious Crimes Unit One?
Yes, sir.
(Serious Crimes Unit One)
Wait a minute.
Corporal Park asked me to look into something for him.
What was that?
He wanted personal information of Professor Mok.
What? Professor Mok?
That's right. He wanted to know his domicile,
whether he lived there in 1986. That's what he asked.
He said it was extremely urgent,
so I searched through the Hwayang University Hospital website...
and even made a call to a cousin that works at the register office.
Please send me that data.
(Chief Jeon Sung Shik)
Then...
he's really gone back to the past.
If we had known he'd go back like this,
it would've been better if you hadn't found out.
It's okay.
I always wondered...
who I was...
and what my parents were like.
I think I can finally move on.
I'll have to handle things on my own from now.
Thank you for...
telling me.
(Sunhwa Boutique)
Lieutenant Kim, what brings you here at such a late hour?
I need to talk to you.
About what?
By any chance, did you meet Kwang Ho yesterday?
Corporal Park?
No, I didn't meet him. Why do you ask?
I couldn't reach him since last night.
But then I heard that he came here.
You can't reach him?
Are you saying that he disappeared?
Did you not see him yesterday?
I went home at 9pm. I would've missed him...
if he came here after I left.
But...
why do you have that scar on your face?
You mean this?
I was organizing my books,
and a few of them suddenly fell on my face.
Why? Does it look like I fought with someone?
- Thank you for your cooperation. - No problem.
By the way,
did something happen to Corporal Park?
We're still trying to find out.
Bye.
22-year-old Lee Jung Sook, 20-year-old Kim Kyung Soon,
23-year-old Hwang Choon Hee, 26-year-old Seo Yi Soo,
and 19-year-old Jin Seon Mi.
They were all someone's daughter or mother.
Right now, they're all dead.
We need to catch the culprit and show them justice.
We need to wipe the tears off their family's faces.
There's nobody else I can tell this to.
Young Ja, please help me out.
My goodness, did you do everything yourself?
You're awake.
You're pregnant, so I'll do the laundry from now on.
Yeon Sook, do you want to eat strawberries?
- Strawberries? - Come here.
- Here. - Goodness.
It's a bit late, but I want you to have a lot of them.
Who could that be? Is it Reporter Oh?
Hello?
I'm Young Ja.
Hey, Young Ja.
Those women who died didn't do anything wrong either.
You know that, right?
Yes, I do. They did nothing wrong to deserve such a thing.
I'll...
testify.
Thank you, Young Ja. Thank you so much.
Yeon Sook, I'm going to go catch this jerk.
I can lock him up in prison now.
You're going to work today?
Yeon Sook, I'm sorry. I'll be right back.
Do you have to go? Can't you just stay home today?
What?
I just want you to stay home today. Please?
Kwang Ho.
I'm sorry, Yeon Sook.
You always say that.
Yeon Sook.
Yeon Sook, look at me. Will you?
Yeon Sook.
I...
really won't take long.
I promise.
My goodness, why are you crying?
I promise that I'll be right back.
Okay?
You look pretty even when you cry.
You look pretty even when you glare at me as well.
Yeon Sook, don't worry. It really won't take that long.
Okay?
I'll be right back.
(Sarang Adoption Center)
(Sarang Adoption Center Office Room)
Here it is.
There are some people who come back like you.
(Childcare Management: Park Yeon Ho)
My parents' names are Park Kwang Ho and Shin Yeon Sook.
But who's this person?
Really?
Were both of your parents dead when you went abroad?
Yes, that's what I heard.
Sending a child abroad for international adoption...
requires the child's parental consent.
But back then, a relative or social worker would sometimes...
register the child under his or her family before sending them abroad.
Then does that mean I used to live at this oriental medicine clinic?
Yes. The address written there is where you used to live at the time.
(Mooyoung Oriental Medicine Clinic, Hwayang, Gyeonggi Province)
Where in the world is Reporter Oh?
(Daedong Industry)
Why did you get here so late?
Hey, I can't go to Seoul with you.
What?
There's a big news I have to cover. It's a hostage situation.
I'm in a rush, so you'll just have to go by yourself.
You jerk.
You already got everything under control.
She said she's going to testify. You just need to find the culprit.
But don't go back on what you said just because I'm not going with you.
You still have to give me the exclusive. It's mine.
Okay, fine.
Bye.
(Mooyoung Oriental Medicine Clinic)
Excuse me. What brings you here?
You look very much like that newlywed bride.
Do I look like her a lot?
I thought you would probably...
visit me someday.
A young man once visited me.
He asked me about her.
I told him about the day she got into an accident.
I don't know why,
but he cried a lot until his eyes got red.
He sat there for a long time and left.
He must have been looking for my mother.
What?
It's such a relief that he returned.
Mother and Father...
must have met each other by now.
Excuse me. Could you tell me where the college of medicine is?
It's over there.
Thank you.
You mean Mok Jin Woo?
Yes. I have some things to ask him.
Where can I meet him?
He is a freshman. Then he must be taking his major...
- What's wrong? - His grandmother passed away,
so he gave a written notice of his absence.
Does it mean he's not in school now?
I think he went home.
Can I have his address then?
And he committed suicide right after your visit.
- Park Kwang Ho. - Why did you go there secretly?
That is a bit harsh, Corporal Park.
What do you want to say?
Why was it him that Jung Ho Young met...
before he died?
(Hwayang Police Station)
- I'll go now. - Okay.
Why are you so surprised?
He came because he's worried about Kwang Ho.
Oh, I see.
Feel free to contact me anytime you want.
- Yes, I will. Bye. - Bye.
See you, Lieutenant Kim.
Chief.
What brought him here?
Didn't you hear?
Did you talk about Kwang Ho or the accident of 30 years ago?
Why would I do that?
"Where Do We Come From? What Are We?"
"Where Are We Going?"
The title of this Gauguin's painting makes us think about many things.
After he received a letter of his daughter's death,
he decided to paint his last work.
And he painted this.
The origin of self.
It's very important to know where we come from.
If everything that happened in the past was gone,
and we lived a new life every day,
we could learn nothing from the past's wrongdoings.
We are who we are today because of who we were in the past.
The same applies for the murderers.
Who are they?
How did they become murderers who killed people?
As I told you in the last lecture,
they didn't become murderers overnight.
They showed a sign of becoming murderers in their actions...
even when they were very little.
They became murderers over a long period of time.
What kind of family do you think they were born in?
I think they may have had none or just one.
Hey, that could be a bias.
There are many criminals who are white-collar workers.
I think their parents could have mistreated them or neglected them.
I heard the news about parents who mistreat their children.
They were also raised in the same way.
I agree with her.
Even if the parents don't beat their children,
many of them mentally mistreat their children.
Otherwise, the parents could have a mental disorder.
All of your opinions make sense.
Most murderers grew up in underprivileged circumstances.
But that can't justify their crimes.
A black sheep...
could exist in an ordinary family as well.
What could be the past life of the murderer be like...
who marks dots after he kills a person?
It must have something to do with the death of Kim Young Ja.
Did I make a mistake in guessing the suspect's face?
(Background investigation)
(Mok Jin Woo)
Professor Mok really lived in Hwayang 30 years ago.
(Prediction of a suspect's face and background, Male in 40s or 50s)
(Lived in Hwayang until 1986, Moved to Hwayang in 2016)
He couldn't have been certain with just these.
(Serious Crimes Unit One)
Where are you going, Lieutenant Kim?
Chief.
Are you sure Kiddo is all right?
Lieutenant Kim didn't look okay.
When on earth are you going to explain everything to us?
It took the whole day.
Well, I transcended 30 years to catch him.
I can spare another day.
You mean the fact that Kim Young Ja was alive...
influenced the murderer?
Yes. Was my assumption wrong?
I don't understand why he committed a murder again 30 years later.
No.
I think you weren't wrong.
He must have believed that it was a perfect murder.
He realized later that it wasn't.
Plus,
if he is the type of person who marks dots consistently like this,
he must have been unable to stand it.
Where do you think such behavior comes from?
Unlike Jung Ho Young,
he's not a show-off type of murderer.
Marking a dot is not for showing off.
As a forensic doctor,
what is different between Jung Ho Young and the criminal 30 years ago?
In the cases of Lee Seo Yeon, Yoon Da Young, and Nam Ju Hee,
the ligature marks are different.
Lee Seo Yeon was choked many times.
Yoon Da Young and Nam Ju Hee were choked once.
A criminal's trait is usually revealed...
in his crime methods.
It's because killing for pleasure...
and killing with intentions are different.
Did you find out who had been looking for you?
Yes, I did.
You were right.
A chance came at the right time.
That's great.
I found the person,
but he disappeared again.
(Lieutenant Kim Sun Jae)
Hello, Lieutenant Kim.
(Map of Hwayang)
Let's see. He might have started it in the place he knew well.
The place he was familiar with.
He may have become confident because he was not caught.
He may have gone a little farther...
to the places far from home.
Yeon Ho was right.
A serial killer tends to come closer to his house...
as he kills more people.
I thought the first site of his murder was close to his house,
but it was the opposite.
I'm sorry.
For what?
For everything.
Thank you, Lieutenant Kim.
For what?
Just...
everything.
I thought it was a relief that I came to know...
Corporal Park is my father even though it's a little late.
Although I won't be able to see him again.
I'm still glad that I found out about...
what my past was like...
and who my parents were.
Kwang Ho said the same thing at the hospital.
He was glad to have found out that...
you're his daughter. He said he was lucky to have seen you.
She was Detective Park's daughter?
Where were you before you came to see me?
I was at Professor Mok's office.
Why?
I think Kim Young Ja's case had a big effect on the culprit.
I went to ask for his opinion on that.
So what did he say?
He agreed with me.
He said the culprit would've been angry...
after finding out about his mistake.
He also mentioned the ligature marks.
- The ligature marks? - Yes.
He said Lee Seo Yeon, who was killed by Jung Ho Young,
and Yoon Da Young and Nam Ju Hee, who were killed by...
someone else 30 years ago, had different ligature marks.
Lee Seo Yeon got choked numerous times before she died.
- Yoon Da Young and Nam Ju Hee... - He said they got choked just once.
Jin Woo.
Where did he go?
I need to find something before this jerk gets here.
(National Institute of Scientific Investigation)
Did you do the autopsy on Yoon Da Young?
Yes. Why?
I need to ask you something.
The ligature mark on Yoon Da Young's neck...
I heard that she got choked just once by stockings.
Sorry? Who said that?
You must be mistaken.
It doesn't matter if she was strangled once or numerous times.
In the end, she would've died because of the strong pressure.
So you can't judge that by just looking at the ligature mark.
What... What do you mean?
It's impossible to know.
The only person who'd know that would be the murderer.
Who are you?
We finally meet.
Who are you? Why are you standing there?
Where have you been?
Did you kill someone and mark them with dots again?
Did you just laugh?
Lee Jung Sook, Kim Kyung Soon,
Hwang Choon Hee, Seo Yi Soo,
Kim Young Ja, and Jin Seon Mi.
Do you even know their names?
I'm here to arrest you for murder,
Mok Jin Woo.
I don't know what you're saying.
You don't?
Then don't you know me?
You hit my head with a rock in that tunnel.
Why? Are you surprised to know that I'm still alive?
No.
I'm not.
Mok Jin Woo!
You jerk!
You scumbag.
You jerk. Get back.
Come here.
No!
I need to catch him.
I need to catch him right now.
Again?
(Tunnel)
Kwang Ho's back?
Do you know how much I looked for you? I was so worried!
Let's lock him up first. Then we can get him to confess.
We meet again.
We have to let him go in 48 hours.
We need to get something before then.
I feel like I don't have much time.
I have so many things to say to you before I go back.
Do you really believe that I'm the culprit?
I left the fountain pen in the past.
Mok Jin Woo never stopped murdering people.
- About Corporal Park... - Yes?
Don't give up even if your plan isn't that great.
I guess the woman enjoyed it more.
Don't waste your energy. The game's over.
