Tunnel (터널)

What the?

- Where did this bastard go? - Park Kwang Ho!

What is that?

Wait a minute, what's going on?

Don't tell me, don't tell me this is...

Did I return back to the past?

Wait...

How did I come back? I didn't even catch that bastard.

This...

Wait a minute. How did this happen?

Where are you?!

Did he disappear again?

Just like last time?

He went back to where he was.

If this is the past...

Yeon Sook!

This house... Our house...

Yeon Sook, Yeon Sook!

Yeon Sook!

Kwang Ho?

Is it really you?

Yeon Sook.

Why are you coming now? Why?

I've been waiting for so long.

Where were you? I thought you really died.

When you are alive like this.

Yeon Sook.

I'm really late, aren't I? Yeon Sook.

I'm sorry, Yeon Sook.

Just what happened? Where were you?

- Yeon Sook, that— - What are these weird clothes?

- When is our daughter coming? - What?

How did you know it's a daughter?

You didn't know I was pregnant.

You went missing before I could tell you about it.

It has already been 5 months since you've been gone.

5 months?

So the time went the same pace.

What are you talking about?

Yeon Sook.

You asked where I was, right?

No matter what I say, are you going to believe me?

Where were you to say that?

Are you telling me to believe this?

I know you're not able to believe it.

I couldn't believe it at first either.

Remember when I asked about a person with no records?

The fingerprint wasn't in the system, there's no record at all.

What is it that this person has to hide?

That person was Kwang Ho.

The thing he wanted to hide was that he's from the past.

Stop speaking ridiculous words.

The whistle necklace, I know that your mom gave it to you.

I heard it from Kwang Ho, that Yeon Sook,

So your mother,

gave it to Kwang Ho as a gift.

Really...

Is that true?

Detective Park...

Is really Detective Park...

So, at the tunnel, I got hit on the back of my head.

After I got hit, I went to the year 2017 straightly.

- 20...17? - All of a sudden, a rock hit my head.

- Are you okay? - What can I do?

That day, that's when I lost the whistle.

You know this? There's no connector.

There's no connector? That's ridiculous.

It's like this... it's this.. It's like the size of my palm.

This... so, I went to the police station somehow and there for the first time...

So,

you were in the year 2017?

In the future?

You can't believe me, huh?

That why you know that our baby is a girl?

So you're saying that I gave this to our daughter?

Yeah... If it were me, I wouldn't believe me either. Who would? They would think I'm a crazy bastard.

Then,

did you meet our daughter?

Of course! I met her!

Yeon Sook, I was able to recognize her because of the whistle.

This whistle saved our daughter's life.

Also, our daughter grew up well, she's decent.

People from the future would consider her decent.

She's like you, Yeon Sook. Her name's Yeon Ho.

- Yeon Ho? - So Yeon Sook, you took

A letter from both our names. Isn't it childish?

The name's pretty.

I must've been a grandma.

Did you meet me too?

What?

I aged a lot, huh?

No, you were still pretty as ever, my Yeon Sook.

Is that what's important right now? You almost died!

I lived thanks to you.

Do you even know how you look right now? Think about yourself not Jeong Ho Yeong!

Miss, this necklace...

Why do you have it?

Who are you? Huh?

That necklace, you know the necklace, right?

Huh?

When you saved me, you looked at my necklace and asked who I am.

No I didn't, you must've heard wrong.

- You definitely... - No, you heard wrong. Go to sleep.

The phone number that you called is turned off. After the beep, please leave a message...

How did I return to the past?

Is there some kind of condition?

Don't go.

Kwang Ho, don't go.

Yeon Sook, I'm right here.

I am happy.

I am so happy to be back, Yeon Sook.

Where's Jeon Seong Shik?

Hey, why are you questioning all the comrades?

That's not it, Chief. There's something I should've reported.

- Among the murders that Jeong Ho Yeong commited— - You brat.

Why are you digging through a case that has been closed by the police? Don't you know even the prosecutors closed it?

What I mean is that they were not committed by only one person.

So, who's the perpetrator? Huh?

If you caused that mess yesterday, you must know.

- We're still... - I ought to...

Seong Sik...

Stop. You understand?

You guys stop too!

Geez.

I knew this would happen.

This time, the professor was wrong, how can it be someone on the force?

- Are you adding more fuel to the fire? - It's because I'm upset.

Right when he's going to get caught, he doesn't get caught!

By the way, Team Leader... We only have these clues,

so let's just look at all the people that meets these conditions in 2016.

Why not?

Is no one here?

Stop. Stop. Stop! I'm in my right mind (he's sober) but should I just yell?

He's right. If it was going to be easily solved, would it have gone on for 30 years?

Let's figure this out, Lieutenant Kim. We still caught Jeong Ho Yeong.

I can smell that this case will soon become solved.

Is there anyone who doesn't know about your dog nose, sunbae?

- Lets figure this out then! - That's what I'm saying..

Are you part of the family and not the guest, now?

In this peaceful union, why isn't the maknae here?

- Yes, Professor Shin? - By any chance, did Officer Park Kwang Ho, go to work?

Kwang Ho? No, not yet.

He won't answer his phone, and I don't think he came home last night.

- What are you talking about? - I think he disappeared.

Kwang Ho disappeared?

What are you talking about?

The number you're trying to reach is not available.

His phone is still off.

When's the last time you saw him? Weren't you guys together?

Team leader, what should we do now?

We have to meet him.

Let's go, Kwang Ho. I said, let's go.

You go first.

- This was the last time. -Then, you haven't been able to contact him since then.

Track his phone and pull his phone records.

There's no place for him to go here. Thirty years ago, he suddenly disappeared.

Something might've happened.

Then let's file a missing person's report.

You know we can't do that.

Geez.

Really...

How can you be the Detective who was chasing me in the tunne?

- Isn't it a funny fate? - What?!

Funny? Is that funny?

There's no way... he could know.

This is what Jeong Ho Yeong saw when he has a visitor,

and in the end, he committed suicide because Professor Mok went to visit him.

There should be victim's DNA left on this...

If we were in 2017 we would be able to catch him right away...

Yeon Sook, is there anything that's similar to an evidence bag?

- Evidence bag? - Yeah.

Something similar to a vinyl bag should be good.

What is this that you're being so careful with it?

Critical evidence that can put the killer away.

What? Then, can you catch the criminal right away?

No. There's nothing they can do here.

Here, they can only get the blood type.

In the future, with this pen, they can catch the criminal for sure.

I need to keep this safe until DNA testing is invented.

I'll be back.

You're going to leave without eating?

There's no time to waste.

In the future, no one knows he's the criminal.

I have to catch him a day faster, that way, no one will die.

You're not going to suddenly disappear again, right?

No, you don't need to worry.

Also, if something happens, call me on your cellphone.

- Cell... what? - Ah, right.

Wait.

Huh? What? Why isn't it here?

Ahhh. Since it hasn't been invented yet, it's not here.

I'll find a public phone and call you as soon as I can.

I'll be back soon.

Hwayang Police Station

There's no one I recognize. As Seong Shik said, they must've disbanded the previous investigation team.

There's probably no records because the files were burned.

They wouldn't believe me if I said that Mok Jin Woo is the culprit.

Let's find evidence that he's the killer first.

Oh!

Let's find evidence that he's the killer first.
