(Train)
(This drama is fictitious and names, places, organizations, incidents,)
(entities, and jobs are unrelated to real life.)
The forked road envelops two worlds.
That day, our two different choices...
changed our fate.
Have you heard of a ghost train?
"A mysterious train showed up..."
"on empty tracks in the dark out of the blue."
There's one more person...
other than me who saw the train.
(Previously)
All of us...
live many lives simultaneously.
- Who are you? - Then...
who are you?
You crossed over...
the boundary.
Same date, same city.
But everything is slightly different from before.
A live person is dead. A dead person is alive.
And in this world,
there's another me.
We both ended up in different worlds.
Has it ever crossed your mind...
that perhaps, somewhere else, we all live a different life...
with different relationships in another world?
Right now, everything is all messed up.
But my name is Seo Do Won.
Let's start over from there.
Ms. Han!
I'll check over there.
Hello?
It's Seo Do Won from Serious Crime Team Three.
Lee Sung Wook isn't the killer.
There's an accomplice.
He's the real killer.
The 12-year-old case and what happened after.
It was all his doing.
Are you...
Don't come closer!
Stay there. Don't come near me!
- Stay where you are. - I didn't kill them.
No. I didn't kill them.
Look at this. I have proof.
It wasn't me.
I only did as I was told.
Okay. I'll hear your story.
Let's talk over here.
That's it.
Sung Wook.
I didn't drag you into this.
It was your choice.
No. No!
No.
Will you live as a predator that hunts...
or as a bug that gets eaten?
Don't come near me. Don't.
Again, the choice is yours.
Don't come here.
Listen carefully. Lee Sung Wook is an accessory.
The murderer is someone else.
You must get Lee Sung Wook and make him confess...
who the killer is.
Ms. Han.
(Train)
(Mukyeong Police Station)
How is Mr. Seo Jae Chul?
Then is the worst over?
(Director of Detective Division, Oh Mi Sook)
I understand.
Do Won.
Ms. Oh.
(Serious Crime Team 3)
(Mukyeong Police Station)
(Senior Inspector Seo Do Won)
(Mukyeong Serial Abduction and Murder)
He was here.
Where did he go?
How is Lee Sung Wook?
Detective Kang took him to the hospital.
He's in surgery now.
The bullet didn't hit his organs, so it's not life-threatening.
But he hurt his head when he fell.
As he's in critical condition, the doctor can't promise anything.
If you located his hideout,
you should have called for backup and used more manpower.
Why did you guys go without reporting to me?
Look at the mess you created.
Who fired the gun?
I did.
After finding out Lee Sung Wook's hideout,
it was me who acted on my own without reporting to you.
And it was me who fired the gun as well.
Why did you do that?
I wanted...
I wanted to catch him myself.
I hadn't confirmed that it was indeed his hideout.
And I thought working as a small group was more efficient.
My judgement was clouded due to my personal feelings.
I take...
full responsibility.
However, Inspector Han's firing was justified.
If she hadn't done it, she would've been in danger.
So right before you got to arrest Lee Sung Wook,
he wasn't himself and fell from the building?
And he kept denying the crime?
To me, that's what it looked like.
If he dies from this,
the case will close as there's no right of arraignment.
Keep checking on his status.
Yes, ma'am.
Mr. Seo, I'd like to talk to you.
Mr. Seo.
Lee Sung Wook lost his vision in his right eye.
It's an acquired condition from an accident.
After his vision of his right eye became narrow,
he's been using his left hand on purpose.
And I confirmed that again today.
But according to the autopsy report,
the culprit who hit Jo Young Ran's head was right-handed.
Even if Lee Sung Wook used his right hand,
accurately hitting the same spot multiple times would be impossible.
Lee Sung Wook isn't the killer.
There's an accomplice.
He's the real killer.
Let's look into it more.
I didn't fire my gun...
to protect myself.
Even if...
I have to turn in my badge,
I have nothing to say.
I would have killed him...
if I arrived at the scene a bit earlier.
I'm sorry.
I'm sorry I wasn't here.
I'm sorry I left you all alone.
Yes. The suspect is being transported to the hospital.
We will brief you on the details of the incident tomorrow morning.
Hello, this is Serious Crime Team Three of Mukyeong Police.
Yes. You can refer to the press release tomorrow.
Hello, this is Serious Crime Team Three of Mukyeong Police.
It's about Lee Sung Wook.
I must look into him more.
There might be an accomplice.
An accomplice?
Given the circumstances,
Lee Sung Wook might have been an accessory,
not the principal culprit.
We must expand our search...
and confirm that there was an accomplice.
Do Won.
Let us handle this case.
I want you to go to this address first thing tomorrow morning.
(Hwajin Nursing Home)
Why?
I had him admitted there.
Your father.
This is the most important task for you more than anything now.
I don't think...
your father has a lot of time left.
He's at the end stage of liver cirrhosis.
It's untreatable.
That's why he went to see you for the last time.
What happened?
I have returned...
to my world.
When I was in your world,
I was curious about where you disappeared to.
I had no idea that we had switched places.
What about Lee Sung Wook? Did you catch him?
What do you mean there's an accomplice?
What do you mean someone else is the real culprit?
Mr. Seo.
Don't get the wrong idea.
Detective Kang isn't calling for you.
He's calling for me.
Mr. Seo?
What is it?
- But your clothes... - Get to the point.
I see. Okay.
I'm coming back from the hospital.
I wanted to tell you about Lee Sung Wook's condition.
Hospital?
The hospital where he was transported to.
Lee Sung Wook got hurt?
You saw everything. You saw him fall.
He's still in surgery.
The surgery will end sometime around tomorrow morning.
But the doctor said he might not regain his consciousness.
What? Are you not done yet?
No. I'll go inside.
So it was that night.
That night 12 years ago.
That's when we went into two different worlds.
I met Seo Kyung.
But you didn't.
That's why...
(Kyeongmu-dong Hill)
Do Won!
He's causing trouble every single day.
Do you think he's dead?
He's badly hurt.
Excuse me.
Father. Hang in there.
Dad.
(Kyeongmu-dong 528-2, Songin-Gu, Mukyeong City)
528-2.
The guy who was with Lee Sung Wook that night is the culprit,
and he's been using the train...
to commit murder and keep it a secret?
That means he was the one...
who left the tools and jewellery in Lee Sung Wook's locker.
Then why did he stop committing murder...
in my world?
Maybe he's already in jail for something else.
Or he might even be dead.
This world is very different from your world.
Just like you and me.
Inspector Seo Do Won, a competent and just detective.
It's time you go back to where you belong.
I can't do that.
Then what are you going to do?
Are you going to live in the dark...
just like earlier?
You don't belong here.
Go back. I'm going to catch him.
If you wanted to catch him so badly, you shouldn't have lived this way.
What can you do when you can't even do anything without drugs?
You're...
the worst version of myself.
What do you know?
Do you think things would've been different...
if you were in my shoes?
What about you?
You hid the truth because you were scared...
to live as a murderer's son.
I didn't hide anything. I was just trying to protect her.
I had to protect Seo Kyung that way...
even if that meant I had to become a coward.
Then why did you leave her to die?
The daughter of the victim that died 12 years ago.
What if you hadn't lied to her about what happened?
Do you still think she would've died?
She died because of you.
I may be a piece of trash,
but you lost your father, while I saved mine.
You saved no one.
But I was different.
I'm going to catch him myself...
before my father passes away.
So just get lost.
You're the worst version of myself.
I may be a piece of trash,
but you lost your father, while I saved mine.
You saved no one.
But I was different.
Okay, got it.
(Cell phone call history, Lee Sung Wook)
Ms. Han, the phone number you asked me to check...
turned out to be a burner phone.
- What number? - Lee Sung Wook...
called the same number...
after kidnapping each of his victims.
But it turned out to be a burner phone?
Does that mean he had an accomplice?
Nothing is for sure.
If Jo Young Ran was killed...
by an accomplice and not Lee Sung Wook,
then it'd be hard to guess why.
What's that?
The victims' belongings.
I found them in the safe in Jo Young Ran's office.
Jo Young Ran had this?
(Lee Ji Young)
(Lee Ji Young, Jung Kyung Hee)
That means she knew...
what her son was up to.
I'm so scared of Sung Wook.
I thought they fought due to money problems.
But it wasn't that.
Then that explains why the accomplice killed Jo Young Ran.
He wanted to shut her up.
Gosh, does that mean Lee Sung Wook stayed quiet...
even though the accomplice killed his mother?
Lee Sung Wook was the one who kidnapped the victims.
If she exposed the culprit, he knew it'd put him in danger,
and they also had issues regarding the inheritance.
(Janghae Foods, Park Tae Kyung)
This person must be Lee Ji Young's acquaintance.
(Janghae Foods, Park Tae Kyung)
- Call him. - Okay.
Where's Mr. Seo?
Earlier, the director told me that he's...
(Hwajin Nursing Home)
Father.
(Seo Jae Chul)
Why are you here?
Why didn't you tell me the truth when you came last time?
I already put you through enough.
Dad.
Detective Oh told me...
that you guys found the real culprit.
I don't think I'll be able...
to stay alive...
and see my name get cleared in court.
But at least I got to see you free yourself from guilt.
And that's what matters.
Keep your chin up...
and be confident.
That's how I want you to live.
It's nice to meet you, sir.
- Ms. Han. - I was told...
that you're here.
Oh, right...
Well...
I'm Han Seo Kyung, your son's subordinate.
And the victim who was killed 12 years ago...
was my father.
I'm sorry.
I wanted you...
to die in pain.
I lived all my life wishing that.
But I found out...
that you were also a victim.
I'm sorry.
I resented you for so long.
Humans are so foolish.
Now that I don't have long to live,
all the grudges and fury I felt,
I don't remember anymore.
I should've carried you once more when you were young.
I should've cooked you one more meal.
That's all I think of and it hurts.
So you should...
leave the torture you put yourself through.
I'm sorry.
Thanks for coming here.
It can't have been easy.
Yesterday.
What did that mean?
When you apologized.
I just thought that...
if someone had been there for you when you were 17,
then maybe you'd have been a little less lonely.
That's how it was for me.
I met someone...
and managed not to get lost.
Let's go.
I'm grateful too.
I also found a reason. A reason to live.
Who was that?
The person I told you about last time.
She was my little sister, my family,
and the one I loved.
But now...
I'm afraid.
I know...
how much it hurts to lose a father.
What?
You spoke as if you've been through it.
That's why I want to get him...
before my father passes.
You were right.
Lee Sung Wook had an accomplice.
That day 12 years ago, outside your place,
someone saw Lee Sung Wook's car.
There was someone in the passenger seat.
It was that passenger who killed your father.
A witness? Who's that?
Let's look into people Lee Sung Wook knew.
Starting with his classmates.
Do you remember this person?
I don't.
(Choi Seong Hak)
It's him. Yes, I remember him.
He was so timid and shy.
He was always an outcast.
He was bullied a lot because of that.
Kids call people like that "a shuttle".
That's way too different from the Lee Sung Wook...
that I remember.
When did you first meet him?
When he was 20.
That's when my dad remarried.
Until my dad died,
Sung Wook lived with his father's family.
Do you remember anything else about him?
Oh, I think it was when we were seniors in high school.
- Darn you. - Stop it. Let go.
Hey.
- Don't. - Keep your hands down.
Darn it. Hey, you. Get lost.
Step on him.
Please, stop.
Don't hit me.
Step on him harder.
My gosh.
Do you remember which school uniform it was?
Not really. It wasn't a school in our area.
Do you remember anything else about Lee Sung Wook?
It was so long ago.
You could've called. I had to drop by your police station anyway.
I didn't come about this.
I came to see you.
What's this?
Oh, that? I saw the surveillance footage,
and it looked like Lee Sung Wook dropped it as he fell.
It's Lee Sung Wook's?
It was Lee Sung Wook.
The owner of the car you saw.
There was a record of the accident.
(Traffic Accident Reports, Mukyeong Police Station)
April 15, 2008.
A week after your father's hit-and-run.
He was drunk and drove into a utility pole.
I guess that's how he hurt his head.
Who's the guy next to him?
It looks like Lee Sung Wook's friend.
I don't know where he is now.
Lee Sung Wook is at the Institute of Forensic Psychiatry.
- It's the real killer's. - What?
Where is this now?
People from your station took it.
Your team should have it now.
- That scar... - I have to go.
That's odd.
I thought he got it erased.
If he wore a school uniform then,
he'll be in his early 30s now.
To Lee Sung Wook,
the real killer would've looked like a role model.
If that's when they got together,
it makes sense how Lee Sung Wook began to change then.
That's all we can find out through his classmates.
The witness you mentioned from 12 years ago.
Is it your father?
I thought about it.
Your father lost consciousness in my home.
Was that a coincidence?
What if there's a clue within...
your father's lost memories?
He had no memory back then.
Could he remember something 12 years after that?
How about trying hypnosis?
Someone helped me not long ago.
It's not admissible as evidence,
but we might be able to recover your father's memories.
The culprit Detective Oh told me about isn't the real culprit?
He's an accomplice. And I'll catch the real culprit too.
I'd like to try what the lady suggested.
I want to get my memory back.
Not in your state. It's too much.
I wanted to know what happened...
while serving time for something I couldn't even remember.
I only found out that I didn't kill that lady's father.
But I must find out what happened to me that night.
Only then, I will be at ease.
You're back, Mr. Seo.
Where's the jewellery you took from the scene yesterday?
Are you asking about Lee Sung Wook's belongings?
I put them in the evidence storage for now.
Is your father all right, Mr. Seo?
Why do you ask?
You used to badmouth him, calling him a murderer.
Do you feel bad now?
Gosh, that crazy jerk.
I thought he was being too quiet for a while.
Worrying about him is a waste of my time.
Hello, Mr. Seo.
Your father wants to try hypnotherapy?
Okay. I'll look into it and call you back.
(Hammer and 8 more items, May 7, 2020)
Mr. Seo?
I thought you were...
at the nursing home.
(Public Official ID, Han Seo Kyung)
"Han Seo Kyung".
It's you.
The reason that jerk won't leave this world.
Pardon?
How interesting.
In this world, you and I...
wouldn't have crossed paths.
That jerk changed a lot of things.
Jae Hyuk, I can't figure out Mr. Seo.
Did you eat?
What? Yes, I did. You should eat.
Come to think of it, he was acting strange yesterday too.
He was like a different man.
No, that's not it. His old self came out.
Who are you talking about?
I'm talking about Mr. Seo.
On some days, he's nice. And on some other days, he's cold.
I want him to just pick a lane. It's hard to get used to both.
It would be weird if he's himself now.
His father served over 10 years in prison for a crime he didn't do.
Now that he cleared his name, he might pass away soon.
Let's cut him some slack for some time.
(Dr. Seok Min Jun)
Yes, Dr. Seok. It's me.
I have a favour to ask you.
Of course. I can help.
It's not that hard anyway.
And it's coming from you too.
Okay. See you tomorrow then.
Be honest with me.
Father, do you really not remember?
Just tell me that you killed him
Tell me that I'm the son of a murderer.
Tell me that I should just accept it and live my life.
I keep thinking that...
there might be a one-in-a-million chance that it might not be you.
Why do you drive me crazy?
You're driving me crazy!
Detective, what should I do?
What if I really killed him?
What about my son? What about Do Won?
Father.
Should we stop here if this is too much on you?
Then, let's go back to that day.
April 8, 2008.
Excuse me. I'm the repairman who came by this afternoon.
I...
left my phone here.
Excuse me.
Hey, I... My gosh. Sir, I left...
I left my cell phone here.
Where did I leave it? It should be here...
Father. Father, are you okay?
The culprit was in the house.
He was there when I went inside.
What about his face?
Did you not see his face?
Should we try again?
No, let's call it a day.
When I came to, no one was there.
My gosh.
I saw a dead man, and I touched him.
My gosh.
A prescription bottle?
There was a prescription bottle there?
I don't remember seeing a prescription bottle that day.
Do think my memory might be mistaken?
I checked the list of evidence and photos of the crime scene,
but I also didn't see a prescription bottle anywhere.
That means the culprit came back...
to the scene.
It was probably a kind of drug...
that could easily reveal his identity.
This is an anti-psychotic drug called tetrabenazine.
It's normally prescribed to patients with Huntington's disease.
"Huntington's disease"?
It's a rare genetic disease.
They slowly lose the ability to control their muscles...
which leads to motor dysfunction.
The brain doesn't function properly as the illness gets worse,
and they experience delusions, dementia, and loss of memory.
Then they eventually die.
This drug is used to ease the symptoms of chorea.
If it's a rare illness,
how many patients would there be?
Probably around 100 people in our country.
You have friends in the medical association, right?
Get me a list of all the patients. I have no time.
You must be tired.
Victims tend to get exhausted...
after they receive hypnotherapy.
You must be asking yourself, "what if I hadn't taken that route",
or "what if I had taken that bus I missed?"
You're probably thinking that things could've been different.
There's a reason why people talk about fate.
It's called fate because you can't avoid it.
I regretted it dozens of times a day when I was in prison,
but I started to accept it after a few years.
That was the only way for me to breathe.
I asked Seo Kyung to bring this.
It was at the crime scene,
and I figured it might help you regain your memory.
Seo Kyung told me...
that this music box was playing in the living room that night.
I'm guessing it was also playing when you were unconscious.
Do you really not remember?
All I remember is what I told you earlier.
I guess it happened too long ago.
Hey, Detective Kang.
Okay, I'll be right there.
Lee Sung Wook has regained his consciousness.
Your father was given pain killers, so he'll be asleep for a while.
How do you know that doctor?
He's my doctor.
The trauma center at work introduced me to his hospital.
Did something happen yesterday?
You seemed a bit different...
when I saw you in the evidence storage.
You seemed like a totally different person.
Hello?
I saw the weather forecast today.
It's going to rain tonight.
It's time you go back to where you came from.
(Therese: The Chronicle of a Woman's Life)
You left that evidence in my locker...
with my fingerprints on it, didn't you?
How could you do that to me?
Shouldn't you start out by asking me...
why I killed your mother?
I gave you a chance to decide...
whether you want to live as your mother's son...
or a blind beast who's crazy about money.
Not reporting me while knowing that I killed your mother?
You did that.
I...
I always did what you asked me to do.
I'll go to the cops now and tell them everything.
Are you sure?
Who would believe you?
You have no evidence.
He may have regained consciousness,
but it will be hard for him to fully recover.
We'll keep him under observation,
but there can be a lasting after-effect.
By after-effect you mean...
The many disabilities that can be caused by traumatic brain injury.
There can be behavioural or cognitive disabilities.
Cognitive disabilities?
An intellectual disability.
He'll have the intelligence of a young child.
What happened to Lee Sung Wook?
He bumped his head against a telephone pole.
He was driving after he had been drinking.
What's wrong, Mr. Seo?
(Hwajin Nursing Home)
Hang in there a bit longer, Father.
I will bring him to you.
That jerk.
Did you find out?
I have a list of patients.
If it's urgent, I'll send it to your phone.
(Unavailable for a short while)
I guess you really can't avoid fate.
I let you live twice.
Is no one there? Help.
Is there...
Why is this name...
You're Seo Jae Chul's son, right?
He disappeared.
Father.
Father disappeared?
It's fine if you're not involved.
- Ms. Han. - I heard.
Father!
(Kyeongmu-dong 528-2, Songin-Gu, Mukyeong City)
528-2.
I'll look inside.
Father.
Father!
The forked road envelops two fates.
Father!
Father?
Do Won.
But I realized only after reaching the end of both roads.
Father!
Do you think he's dead?
I was not part of fate.
Fate was part of me.
Father.
I was...
fate.
(Train)
- Who on earth are you? - I am the dead Seo Do Won.
The dead Seo Do Won is me.
I feel like the same things keep happening.
That scares me so much.
I'm afraid I'll lose everything again.
Only Seo Jae Chul died?
How is he alive?
Some choices save lives,
and some kill.
Someone was chasing my father.
The only person who'd hurt him now.
The person who must cover up the case from 12 years ago.
It was all him.
I'll stop him this time, whatever it takes.
