[eerie music]

[static scratches]

[deep inhale]

You really shouldn't have come here today.

Why?

This is not my fault.

What are you saying?

That person…

is here right now.

"That person"?

Who?

[doors squeak open]

[menacing music]

[Sigma] Look who's here.

[Sigma inhales]

We meet at last, Han Tae-sul. [snickers]

What's going on here?

Oh, this? Ask this old lady here.

-[laughs] -[doors squeak open]

[Mr. Park] Hey, hey, watch it!

Come on! Come on, man! Take it easy.

Okay, okay, I won't do that again. Hey, hey, let me just take these off.

-[Mr. Park chuckles] -So it was you.

Oh…

[inhales] It's been a while.

[irked sigh] Why in the world did you bring him here?

Hmm, Mr. Han here kept hounding and hounding me about the drug,

so I had no choice.

[sharp inhale] You messed up everything, you bastard.

[chuckles] Well, hallelujah. Sister Agnes.

We both have done some terrible stuff, haven't we?

And you can't undo it all with prayer.

[Mr. Park laughs]

[Sigma] Enough.

Let him out.

-Stop it. -[chains rattle]

[gate opens, closes]

[clink]

[sighs]

Uh, hey! We're in this together now, huh? [laughs]

101, I told you I can't stand people who don't keep their promises.

[Mr. Park] You are the one who didn't keep your promise.

Why didn't you send my wife and my kid?

I kept my promise.

I found your wife and daughter for you,

and then I took them to where the uploader was.

[Sigma] It was their decision to get on or not.

Your daughter…

maybe she doesn't wanna see you.

[cackles]

You know… [chuckles]

I swear, I'll kill you one day.

[sinister music]

[Sigma scoffs]

Some morons can't seem to handle it when they're treated with respect.

Sit down.

Sure, thanks, man. [laughs]

[Mr. Park] Oh, boy.

I know we just met. Sorry, it got a little tense there.

Han Tae-sul, pleasure to finally meet you.

Likewise.

Last time we met, you took off. Why is that?

Hmm, that wasn't a good day for us to meet.

Today is?

You're prepared to meet together today? So is this a formal meeting?

Well, I actually came here for Agnes.

[Sigma inhales] Then again, I did think you might be here.

Turns out you were.

Had I known you'd be here, I would have put on a nicer outfit for you.

[chuckles]

Why are you here?

The drug.

[mocking tone] Oh, no.

I guess that girl must have gotten the shot.

You probably know this already.

Agnes developed that drug to torture folks from the future.

[Sigma] She despises illegal entrants.

But why do we have to give you the drug?

[eerie music]

Agnes, he thought we'd just hand it over. [laughs]

[deep inhale] Well, on a side note,

I really don't understand why someone would make poison

and also create an antidote for it, you know.

I mean, just don't do something you'd regret in the first place.

Why go to such great lengths to undo it?

Don't you agree, huh?

[Sigma sighs]

In my opinion, most people are fickle-minded

because they aren't honest with themselves.

What are your thoughts?

[laughs]

What? What's funny?

[chuckles]

And I suppose that you think you're being honest with yourself, huh?

[hums in wonder]

I know what kind of person I am in the world.

And I also know exactly what I want.

Which is why I never change my mind and don't lie.

That means you can believe every word I say.

Hmm…

You're willing to start a war, but you're saying lying is something you don't do.

Mm-hmm.

[sighs] Okay. So then, what do you want from me?

The uploader.

If you're able to finish coding it, I'll make sure the girl lives.

I don't want to.

Why not?

-Why not? -Mm-hmm. Isn't it a good offer?

[deep inhale]

Well, um, the world is going to come to an end because of the uploader, so…

Uh…

To be accurate, it's just the Korean peninsula,

not the entire world.

Wait, the world can't come to an end? Why?

[cackles]

Oh, god, that bastard's crazy.

[Mr. Park laughs]

People always swear when they have nothing to say.

Hey, I'm not at all crazy.

So answer me.

Why can't the world come to an end?

Well… [sharp inhale]

Where do I even begin with this one?

First off all, hmm, you see, normal regular people

do not want the world to come to an end.

You're wrong.

Step outside and ask people this one question.

"If there was a button that can nuke the entire world right in front of you,

would you press it?"

I bet so many people would say that they would.

[Sigma] Go on the internet.

You see countless people who want the world to end.

And some of them say, "This planet's way too crowded.

We'd be better off if we wipe out 75 percent of the population."

Han Tae-sul.

I bet you're no different.

[heavy music]

[deep inhale]

Let's try an experiment.

Okay?

[gun clanks]

[gun cocks]

Take it.

[Sigma] You know how to shoot a gun, right?

All you do is pull the trigger.

[eerie music]

[tense music]

Shoot me.

If you kill me right now, then you can save the world.

Do it.

[tense music continues]

Come on now.

Do it.

Shoot me, Tae-sul.

[tense music]

[sighs]

[tongue clicks]

[footsteps]

You see.

You just chose to nuke the world.

[Sigma] I bet this was your train of thought.

If you kill me, my friends here will kill you,

Agnes, and 101, which means you won't get your hands on the drug.

And that girl will die.

You just made a decision that would end the world all cause of some girl.

See, that's how people behave.

Don't be hard on yourself.

People put their families, themselves, and their money first

even if they know everyone's gonna die.

Agnes is the same.

I take good care of her mother, so she can't shoot me.

Neither can 101 since he wants something from me.

[serious music]

I've given everyone here a chance,

yet not a single person chose to save the world.

To be completely honest with you, I don't care about the future.

I really don't. I mean, why should I?

[Sigma sighs]

And all you people call me a bastard.

You're the bastards.

I'm not the one to blame here.

Then…

[inhales]

why did you kill Kim Dong-hyeon?

[dark music]

You said you never lie, so tell me.

-Kim Dong-hyeon-- -[Tae-sul] And my brother.

Why? What did my brother do wrong, huh?

Why are we all the ones at fault for putting the blame on you?

-Your brother-- -You have been continuously deceptive

and you falsely lay the blame on people who do not deserve it, hmm?

Don't cut me off.

No, I didn't do anything to him.

I really didn't.

Well, I may have scared him a little,

but 101 and Agnes put your brother through hell, not me.

[Sigma] They deceived him and used him.

I guess you haven't told him yet.

[chuckles] Look, we were just business associates.

I will, uh, give you the details later.

[Sigma chuckles]

[inhales]

Kim Dong-hyeon, he betrayed me.

I made a brokerage clerk into a tycoon, and then he tried to kill me.

I took back what I had given that man.

[Sigma] But come to think of it,

101 and Agnes weren't the ones who tortured your brother the most, right?

[eerie music]

It was you, Tae-sul.

[dramatic music]

Okay, let's start over. I'll ask you again.

I planned to get the blueprint from your brother.

But thanks to someone, he got away.

Are you going to make me the uploader?

Get lost.

[laughs]

[wheezes]

That's your answer?

[inhales]

[sighs]

You said you came here for the drug.

Take it.

[eerie music]

There's a specific way to inject it. If you're not sure, take Agnes with you.

What are you up to?

I just like you.

[scoffs]

[laughs]

I wasn't ready for an answer like that.

[chuckles] No, really. I mean what I said.

You're very special to me.

You're the last puzzle piece for my plan.

That's why I chose to invest in your research.

[dramatic music]

[Sigma] If it weren't for me, you'd still be stuck

in that shipping container in the middle of nowhere, running your physics engine.

Right?

Everything you've achieved so far, you owe it all to me.

You ought to be grateful once in a while.

[dramatic music continues]

101.

What should I do with you, huh?

I'm the one who dug you up, so I can put you back into the ground.

[snickers]

[Mr. Park laughs]

I'll spare you for now because I think you're useful, okay?

[playful tone] But if you betray me one more time,

I'll send your wife and daughter back to you, dead.

[sinister music]

Do you have any questions for me? Is there anything you'd like to say?

[sharp inhale]

You snuck into my place

and wrote "Do not look for your brother" behind the painting. How did you do that?

IF YOU DO, YOU'LL DIE

I used spray paint.

How did you get inside?

Ah.

[inhales]

You see…

I can easily get in anywhere.

Is that it?

Good.

I'll be seeing you again.

[tense music]

Actually, I didn't wanna bring this up, but…

[Sigma] Han Tae-sul.

Do you remember me?

[tense music continues]

I guess you don't.

[doors squeak]

[doors close]

[sighs]

[keyboard clacking]

[sighs]

[chair clonking]

Easy. So, um, you, you guys aren't gonna run?

You shouldn't stay here. I heard that there's gonna be a war.

-It's all blocked. -What's blocked?

If illegals go to the airport, they're caught by the Control Bureau.

Don't you know who they are?

Oh, of course, I do.

[keyboard clacks]

[alert alarming]

Damn it! [Bingbing sighs]

That's the downloader? The thing that brings people from the future?

What? It's not working?

That jerk, Tae-sul, backed up the server.

Oh, so then, there's not gonna be a war. Isn't that good?

[Jae-sun] Oh, I guess I'm wrong.

Then… Ah! Do you have to shut down the store?

None of your business.

I'm waiting for someone.

Who?

Shut up, will you? You're really getting on my nerves.

It's illegal to own a firearm without a license,

and minors can't possess or carry guns.

Ah, is that so? Didn't know that.

[scoffs]

-Uh, hey. -What?

Uh, did that weird Sigma dude come in through that?

-Uh-huh. -And he started the war?

-Mm-hmm. -Is Tae-sul really a genius?

He's the only one that can fix this?

It's his invention.

He invented both the downloader and the uploader.

So if Tae-sul doesn't exist, Sigma doesn't exist either.

[dramatic music]

Because the uploader hasn't been invented yet. Am I right?

And we'd have no war either.

Well, I guess so.

[static crackles]

By the way, why are you here?

That visa was very expensive.

[sighs]

-I should get out. -You better hurry.

-Hop on a plane while you can still leave. -[mouse clicks]

[sighs]

Yeah.

Is everybody as rude as you in the future?

[sighs] I don't know. Why?

Nothing. Just curious.

[door clanks open]

-[footsteps] -[Jae-sun sighs]

You get the drug?

[static crackles]

[exhales]

[digital trilling]

She seems to be asleep, but she's in a state of temporal displacement.

[exhales]

She's here to help us.

The receiver.

[receiver clanks]

We gotta get started.

If you're not helping out, leave the room.

All of you, leave.

What did I say? All of you, get out now, except for Tae-sul.

-Me too? -What, you wanna do this?

Should I go out, then?

Fine. But get it done. No funny business, okay?

Guys, let's go.

[ominous music]

[heavy sigh]

Come on, let's do this.

[serious inhale]

She's temporarily displaced at the moment.

[Agnes] She seems to be asleep right now,

but she's actually wandering around through different points in time.

I heard. So what now?

[inhales]

If we give her the injection here, she's not gonna be able to wake up.

Someone has to go to where she is and administer the injection there, so…

But that's dangerous.

It physically takes a toll on you.

[clanks]

[sighs]

[receiver clanks]

[chair clonks]

[sharp inhale] Wait, Tae-sul.

If you fail, you'll never be able to come back, okay?

First, let's find out what's going on. When we know more, then…

This is it, right? FOS decomposition.

Why are you doing all this?

I told you.

[Tae-sul] I don't wanna lose her.

[serious music]

[inhales]

Ten milliliters, and the FOS proteins will begin to break down.

And then you'll be transported.

To when, exactly?

You'll go to her past.

[inhales]

That's where you'll be able to find her.

What happens, then?

[sighs] There's one shot for each of you.

There's no more left, so you must pick a safe spot to administer it.

Only do it when you are as close to the present as you can possibly be.

Understood?

[container clinks]

If you lose this or make a mistake, you can never come back.

And you'll wander through space and time forever.

[sighs]

What?

-Just like a wandering ghost? -[container opens]

[Tae-sul] Hold on.

-[antidotes rattle] -Where's number one?

[dark music]

That one failed.

[nervous chuckle]

Well, that's good to know.

[container closes]

[Agnes] Make a fist.

[Tae-sul huffs]

[Agnes] You know that…

this is exactly what Sigma wants you to do, right?

I fooled you my whole life.

I went in and made you look crazy and boxed you into a corner.

I even locked you up this morning.

[sighs]

Knowing that, you still want this shot?

I have no other choice.

[inhales]

Even if you do this, the future won't change, Tae-sul.

It's not about finding a way to save that girl.

Don't you get it?

[Agnes] A future hasn't happened for you. But for me, it's in the past.

Our past is like our future.

We can't take back our mistakes or the things that we regret.

It's the same for our future.

Your future is a mirror of your past.

It's like looking at your reflection in the mirror.

Even if you're embarrassed by what you might see,

you can't change anything.

Because that is who you are.

Tae-sul.

You can't beat the mirror no matter how fast you might be.

Seo-jin, I don't agree.

I'd say that we…

are faster than the mirror.

[receiver clanks]

[determined inhale]

[exhales]

[clicks on]

-[beeps] -[huffs]

[clicks on, beeps]

[dramatic music]

Good luck to you.

Thanks.

[kid 1] You can't move, so you're out.

-[kid 2] Okay, fine. -[Tae sul coughs]

Hey, kids. Hold on a second. Just a second.

Strangers aren't allowed in school premises, sir.

Oh, I'm sorry. I'm here looking for someone I lost.

She's a woman.

Her hair comes down to here. She's quite tall.

And she's pretty. Think you may have seen her?

[all] No, sorry.

[kid 1] I think you just look to the back.

Are you okay? You seem like you're sick.

-[kid 1] Look back. Try it again. -No, I'm fine.

Go to the hospital, see a doctor.

-[kid 1] Okay, okay, let me play… -[hurried footsteps]

[kid 3 chuckles] Come on.

[exhales, coughs]

[hazy music]

What was that?

[coughs]

Seo-hae.

[coughing continues]

-[Tae-sul] Seo-hae! -[cell phone clicks]

[Tae-sul coughs]

Seo-hae.

Gang Seo-hae!

-[Eun-hui] Whoa! Look at me. -[Dong-gi] Look straight ahead.

-Look over here! -Come on, let's go to Mommy.

-Come on, make a V! -[Dong-gi] Wow!

[Eun-hui laughs]

[Dong-gi] Look at Mommy. Make a V. There you go.

-Keep going. Come on! Wow! -Make a V! Come on, V!

[Eun-hui] Good job. Turn around.

[Eun-hui laughs]

Seo-hae…

[emotional music]

[Tae-sul] Seo-hae.

[heavy breathing] Gang Seo-hae.

Seo-hae.

Seo-hae. [sighs]

[groans] Hey, get off.

[huffs]

-Seo-hae… -[groans]

-[sighs] -[Tae-sul] What's wrong?

Ugh, I have a headache.

Seo-hae, are you all right?

Uh… What… what are you doing here?

I came here to save you.

This is… this… [coughs]

[Tae-sul] Things are very complicated.

But to put it simply, well, I… I traveled back in time

and risked my life to save you.

[chuckles]

I'm so cool, aren't I?

[chuckles]

Thank you.

So what… what do we do now?

We're going home now.

Your parents are waiting for you.

I'll take you to the present and give you an antidote.

[heavy breathing]

[Tae-sul] Hold on.

[serious coughing]

[gasps] Hey, are you all right?

[wheezing]

[Tae-sul gasps]

[eerie music]

[Tae-sul breathing heavily]

[Seo-hae] Are you okay?

MARRIED COUPLE IN THEIR 30S KILLED WHILE HELPING TRAFFIC ACCIDENT VICTIMS

-Where are we? -[Tae-sul panting]

My childhood.

Something's not right.

REST IN PEACE, FATHER AND MOTHER

[young Tae-san] From now on, I'll be both your mom and dad, okay?

I'll pack your lunch for school every day.

With your favorites.

Ham and anchovies. I can make all those things, you know.

[young Tae-san huffs] Nothing's changed.

[man clears throat]

[man exhales]

This has to be tough.

[man] You have to stay strong. You have to, for your little brother.

And stay strong for your father, so he can rest in peace.

Mm, Tae-san.

Uh, I… Uh, man…

[sharp inhale]

I really shouldn't, um, mention this here, but…

-Gosh, I feel horrible. -Uh, you can tell me, sir.

Um, before your dad passed away,

-he borrowed some money from me. -[paper rustles]

[present Tae-sul] That's a lie.

That man's trying to take the insurance money from us.

Tae-san, don't listen to that jerk. He's trying to dupe you.

Hey, take it easy. They can't see us. We're invisible.

PROMISSORY NOTE

BORROWER: HAN DONG-MIN 5 MILLION WON

[nervous exhale]

[sighs]

[Seo-hae] We should go.

[warp music]

[young Tae-san] Yes, ma'am.

I'll go to vocational high school.

I won't go to college.

I'm very sorry.

-[sighs] -[phone clanks]

[emotional music]

[deep inhale, sighs]

[huffs]

[receding footsteps]

[emotional music continues]

[Mr. Park laughs]

Going well?

We can talk when he comes back.

[chuckles]

[Mr. Park] Come on.

If you ever tell Tae-sul

what you did to his brother, he'll never wanna see you again.

[irked inhale]

But it's all your fault.

You promised me that if I got his brother out,

we'd go to Tae-sul together.

[Agnes] But what the hell did you do?

You stole the safe and everything else.

You know, I nearly died because of what you did.

Oh, believe me. I suffered because of what you did.

You let Han Tae-san slip away from us.

Sigma got pissed off, and I almost died.

[huffs]

Now, I'd say we're pretty even, wouldn't you?

We all did bad things, every one of us.

[scoffs] Don't act like

you've never dirtied your hands.

Finish what you're doing. Stop it.

[sighs]

[deep breath]

[ominous music]

[Hyun-seung] You disobeyed orders, committed theft,

conducted an unauthorized interrogation, lost a key suspect,

used your gun, and left the office without permission.

Impressive.

Got something to say?

[eerie music]

-Sir, did I come back? -Why are you asking that?

811 told me.

I'm from the future.

-I took the uploader. -Hyeon-gi.

I told you. We do not believe what illegals say. Remember that.

Is she…

really Lieutenant Gang's daughter?

Yes, she is. That's been verified.

[sighs]

[Hyun-seung] Looks like 811 already met Lieutenant Gang and his wife.

The day we captured the girl, Lieutenant Gang's wife was there.

We have security footage

that shows Han Tae-sul visiting his house a few days ago.

I sent agents over, but he fled.

We're now having to track the whole family.

Based on the info we've gathered so far,

811 didn't ended up at your place by chance.

It appears as if Lieutenant Gang gave her your address

before she got on the uploader to travel back to the past.

Your place was perfect for her. She obtained a gun and a car.

It was useful for her, you see.

Did you always keep a gun there?

Yes.

The ones closest to you are always your biggest threat, do you hear me?

[sharp exhale]

Our superiors are furious you let a suspect get away.

A letter apologizing won't be enough.

[tongue clicks] You're on leave until further notice.

Sir, please let me…

You can come back when things die down.

-Now give me your gun and radio. -Sir, please!

Hey.

[sighs]

[gun clanks]

[tense music]

[badge clinks]

[exhales]

Rest. [Hyun-seung clears throat]

Been a while since I've seen you, sir.

You should have told me you were coming.

I just happened to be close by, so…

[Sigma chuckles] You did good.

But will that be sufficient?

Of course.

DETAILS 1ST HALF OF 2011

[Sigma] Was his name Jung Hyeon-gi?

You see, people…

believe what they wanna believe.

Rather than admitting that his mother died while he was being neglectful towards her,

seeking revenge is much easier than living with guilt.

It's better to blame someone else for things, isn't it?

[chuckles]

[deep inhale]

You're impressive.

[laughs]

Oh, come on.

We've taken care of Han Tae-sul.

And Jung Hyeon-gi has been dealt with as well.

Are we just supposed to wait around now?

Well, we just need to build the uploader.

[tense music]

I'd like to see everyone before I leave. Tell them to come over here.

Yes, sir.

[digital trilling]

[somber music]

[heavy music]

[waves churning]

[somber music continues]

[young Tae-san] Tae-sul, Mom and Dad are in heaven now. I know they are.

Both our parents saved many lives before they passed away,

so I'm sure they went to heaven.

If we do good deeds and never hurt others,

one day, we'll get to be with Mom and Dad again, Tae-sul.

No, we won't.

Huh?

Tae-san, the Second Law of Thermodynamics.

Time is irreversible.

Entropy can never decrease in a system that's thermally isolated.

[young Tae-sul] So natural occurrences and the past-future asymmetry just…

[sighs]

My point is it won't happen. We'll never see Mom and Dad again.

It's impossible.

[emotional music]

[sighs]

You said we have to go forward to 2020.

Why are we wandering around in your past?

[sighs] I don't understand what's happening either.

There's a mix-up.

Well, do we keep moving forward in time?

Don't get upset.

You've been through this already. Just try to move past it.

Okay.

Let's sleep here tonight. It can be our house.

Looks like this used to be someone's bedroom.

Look. This wallpaper.

-What about the light blue? -[young Tae-sul] That's easy.

If you draw these lines, like this,

you can subtract the square from the circle, you see.

How?

First, draw this. Then you draw this.

So what's the answer?

Hmm…

If the radius is about 10cm, it should be about 228cm².

Hmm, you're the smartest kid in the world.

-You cold? -Mm-hmm.

[jacket rustles]

[emotional music]

[crying]

[emotional music continues]

I've never seen him cry before.

He never cried in front of me.

Tae-sul, we have to keep moving.

[exhales]

I know that door scares you.

[Seo-hae] You don't know which moments you'll meet from your past.

I also saw my past.

My mom, dad, and the war.

You have to be prepared.

That's about all you can do.

When is this?

The day Tae-san died.

[past Seung-bok sighs] My goodness.

-[all chuckling] -Cheers.

[past Seung-bok] Let's become rich, Tae-sul.

[exhales]

I gave this guy room and board all throughout our college years,

and you know what?

It turns out that it wasn't all for nothing.

Huh? What? The two of you lived together?

You'll never believe it, but I even hand-washed this jerk's underwear.

And that shipping container with no furnace in the middle of winter,

I ended up with eczema all over both hands.

Just so Tae-sul could focus on his research

and not have to worry about anything.

[inhales, sighs]

Hey, you prick. You better be good to me.

[scoffs] Looks like he's about to cry.

Hey, for real.

[sighs]

-[past Tae-sul] Where are you going? -I noticed a lady over there

keeps staring at me, and it's distracting.

I should go over and talk to her.

So I'll leave the two of you to enjoy your lovely dinner.

See you later.

Hey, Seung-bok! Seung-bok! Eddy Kim.

[chuckles] What's with him?

[past Seo-jin chuckles nervously]

10 MISSED CALLS TAE-SAN

[sighs] Sheesh…

Wasn't that Tae-san earlier?

-Yeah. -[past Seo-jin sighs]

He looks better before he was hospitalized.

Yeah, his drinking might be the issue. [sharp inhale]

He's usually okay, but if he drinks, he starts acting up.

He talks about the future, illegal immigrants,

and how our phones are tapped.

[past Seo-jin] He still does that?

So many people suffer from stress-induced delusional disorder these days.

He should start therapy again.

-[phone clacks] -It pisses me off.

Yeah, but it's still pretty nice to even have a brother, right?

I'm an only child, so I was always bored.

What's so nice about it, huh?

We're so different. Honestly, it's better not to have one.

I'm more comfortable with strangers.

[past Tae-sul] My brother thinks that he practically raised me.

Of course, I'm grateful for everything he's done for me, I am.

But he always goes on and on about what he did for me,

and says I owe him everything.

It's really annoying.

Now that his little brother is successful,

I guess he feels like it's unfair that he made all those sacrifices for me.

That's your past. It's not you.

Crazy jerk.

-It's not you. -Yeah, it is.

[soft scoff]

-That's who I am. -How was I earlier?

[present Tae-sul] I hated myself from the beginning.

I was mean. I wanted everyone to pity me, and I…

thought I was better than everyone.

-Stop, please. -It's not Sigma's fault.

Because of that jerk, the nuke went off and killed everybody.

-[Seo-hae] That's not true. -I'm that one who did it!

Tae-sul.

[gasps]

Tae-sul.

[Seo-hae] Tae-sul!

Tae-sul.

Han Tae-sul!

[tense music]

What's this?

[gasps]

[Seo-hae] Tae-sul. Tae-sul, wake up.

I said wake up!

Let's go. Get up now.

-Come on, get up. -[Tae-sul groans]

[Seo-hae grunts] Let's go. Come on.

-[both grunt] -[Seo-hae panting]

I can't see anymore.

Do you know what we'll see once we walk through there?

My brother's funeral.

And me turning into a rich douchebag who hurts everyone around him.

That's what we'll see.

I haven't spent one day of my life being happy.

Not one day.

[panting]

Go along.

[wind blows]

[coughs]

[Seo-hae] How could you say you've never been happy?

I lived in a bunker eating canned foods, but even I have happy memories.

Every March, after the war broke out, my dad would take me to school.

The school was in ruins, but I'd go with a packed backpack and lunch.

That was the only day I was worry-free.

We just play together in an empty classroom.

And I had so much fun.

And I went to the stadium where BTS had their last concert.

And I saw a huge banner there.

My dad and I carried it back with us to our bunker,

but we struggled the entire way.

We had to hang it outside the bunker.

Uh…

In the future, the sky is very clear.

You can see all the stars at night because there are no lights.

Have you ever seen the Leonids before?

[sniffles]

I once read that, every 32 years,

there's a comet that passes through the constellation, Leo.

[Seo-hae] Whenever that happens, you see an incredible meteor shower.

[sniffs]

There was one in 1998, and no one saw the meteor shower in 2030.

No one, except for me.

I watched it all night, on top of the bunker.

It was so beautiful.

We all have mundane, yet happy memories inside of us.

That's what keeps us going.

I know you have some too. Just think about it.

[sighs]

[sighs]

The sea?

[sighs] [Tae-sul] It's the West Sea.

At what point in time?

See that?

That's Quantum & Time's training center.

[Tae-sul] I told them to build it here because I love this beach.

Construction was supposed to finish this year.

We arrived at the present.

-What are we supposed to do? -Take the antidote and return.

[exhales]

Seo-hae, when we go back,

you'll find your father waiting for you.

[gasps]

Really? My dad's there?

[dramatic music]

[Seo-hae gasps]

-[both grunt] -[vial shatters]

[Seo-hae] How did you bring him over? He believed you? What about my mom?

Yes, he believed everything I said.

And your mom is waiting for you as well at your old place.

-[exhales] -[Tae-sul] You look just like her.

But your personality, you obviously got from your father.

[chuckles]

Thank you for getting me.

[container opens]

[clinks]

You go back first. You were here longer.

-And you? -After you, I'll take mine.

[inhales, sighs]

[tense music]

What?

Nothing.

Now, here we go.

[liquid squirts]

[groans, sharp inhale]

[Seo-hae] I'm dizzy.

Hurry up and take yours.

[Seo-hae sighs]

What are you doing?

I'm sorry, Seo-hae.

For what?

[music intensifies]

-[container closes] -Hey.

[exhales]

It shattered somehow.

[gasps]

Listen carefully, Seo-hae.

You'll wake up at Asia Mart, okay? Go to my place.

You know where it is. You can stay there.

If you have any questions, Sun will be there to help you.

[Tae-sul] And your parents will be with you too.

You…

[Tae-sul] There's gonna be someone you've never seen before.

Her name's Seo-jin.

She came from the future through the uploader, just like you did.

She knows a lot of things about Sigma.

Seo-hae.

Stop him, no matter what.

[Seo-hae sobs]

You can do it.

Hey.

I'm a genius and I've gone over this in my head,

and you should be the one going back there.

They all need you. Go back and save the world.

Even if I were to go back,

no one would be waiting for me.

Everyone hates me, you know.

Seo-hae.

Stop being so serious.

Smile more.

[emotional music]

[romantic music]

[dramatic music]

[digital trilling]

[warp music]

[clanks]

[rustles]

[Agnes sighs]

And Tae-sul?

What happened?

There was only one vial.

[gasps]

[Seo-hae] You jerk.

Hear that?

You hear me, right?

Tae-sul.

Wake up, Tae-sul.

I'll kill you, if you don't. Wake up, Tae-sul!

[Seo-hae] How could you say no one would be waiting for you?

Look, I'm waiting for you.

Hey, Tae-sul!

Come on, Tae-sul, you have to wake up.

[Seo-hae crying]

You fool, Tae-sul.

You're not going to die today.

[groans]

[sand crushing]

[grunts]

[Tae-san] You're awake.

Tae-san?

[gentle music]

I told you that we would meet again, didn't I?

[young Tae-san] Tae-sul, over here.

[Tae-sul's mother] Good job, go get it!

[Dong-min] There you go. Oh, yeah. That's it.

What… what's going on?

We're brothers, so we share the same past.

I told you I'd be hiding in a place that no one could find.

[chuckles]

How are you? You were here all along, then?

[exhales]

[warp music]

[rustles]

[muffled] Tae-sul.

[sobs]

Tae-san.

Tae-san. It was all my fault. Tae-san, I'm sorry.

I'm sorry. I'm so sorry. I'm sorry.

Hey, I said it's okay.

I'm sorry. I'm so sorry.

I'm sorry…

Hey, why are you sorry? Come on.

Huh? I should be saying sorry.

I should've been better to you. Tae-sul, I'm sorry.

But you know, I'm so incredibly proud of you.

You've accomplished so many things.

Thank you.

[sobbing]

Tae-san…

[Tae-san] Oh…

[clinks]

I brought this with me, in case I'd need it.

You use it.

[Tae-sul] Tae-san.

-[spits] -Hold on. Hold on.

[liquid squirts]

Tae-san.

[Tae-san] Tae-sul, listen to me.

Okay? You shouldn't be in here.

Well, I think this is the last time we'll see each other.

We won't cross paths like this again.

Tae-sul, remember this.

Even when you couldn't see me, I was right by your side.

[cries]

[Tae-san] And that won't change.

So when you're lonely, pushing too hard, or exhausted,

look around for me, and I will be there.

Get going.

I love you.

[cries]

[emotional music]

[Tae-sul cries]

[flatlining]

[Seo-hae sobbing]

[digital trilling]

[receiver clanks]

[Seo-hae sobbing]

[inhales]

[sniffles]

I've come a long way to meet you, Tae-sul. I really have.

It was a difficult and terrifying journey.

[Seo-hae] Please wake up.

You're smart.

You can do anything, so please come back.

[sniffles]

Figure out a way to do it.

I miss you. Come back.

[sobbing]

[beeping]

[Seo-hae cries]

[light music]

[Seo-hae sniffles]

[gasps]

Tae-sul.

[Seo-hae cries]

You just told me that…

you miss me, didn't you?

I'm gonna kill you.

I don't wanna die. Sorry.

I thought you were dead!

[sniffles, cries softly]

[grand music]

[relieved sigh]

[cries softly]

[inhales and exhales heavily]

[relieved chuckle, weeping]

["My Last Love (In Paradisum)" by Ailee playing]

[Mr. Park] I still haven't gotten even with you.

[Seo-hae] I can change the future. In fact, it's already changing.

[Jae-sun] Can't you just destroy the uploader, then?

-If you get rid of the person-- -[Seo-hae] Hey!

-[hard slap] -[Mr. Park] Look at that scumbag.

[Tae-sul] Do you think he left it there for us?

[Seo-hae] There's something strange about this painting.

[Tae-sul] This is where it all began.

[U-jin] Suspect spotted. He's at one of our surveilled locations.

-[Seo-hae] Who do you think drew these? -[Tae-sul] There's no name.

[young Tae-san] Tae-sul! Han Tae-sul!

Sigma.
