You're safe. It's okay.

It's okay.

-Dad… -[Dong-gi] You're okay.

It's okay now.

It's all right.

[both pant]

You're okay.

You're okay.

[wind howling]

[Dong-gi] When you're walking, always take the road.

Never try to travel on the sand, remember?

[Seo-hae] Yes.

When you're tired, you have to stop and rest.

Your visibility has to be good.

Seo-hae, never let your guard down. Take the safe route.

-Yes. -Then what happened?

[exhales softly]

You can't get to the uploader by yourself.

Seo-hae.

I want you to have the easiest life possible.

Let's smuggle ourselves to another country.

Never.

I made a promise to your mother.

I'm begging you.

You stubborn little…

Take this.

You wanna go? Shoot me with that first.

[sighs]

Come on, Dad.

-What? -This isn't like you.

What is it that you're so afraid of?

Of someone hurting you and you suffering…

and you dying.

But I'm not.

What I'm afraid of is giving up without even trying.

I can do it. I will do it.

And it's something only I can do.

I can't make it to the uploader on my own.

I need your help to get there.

So, please…

I want to go back to the past.

[dramatic music playing]

[birds chirping]

[music rises]

I MISS YOU, MOM

GOODBYE, MY FRIEND

SLEEP WELL, MY DAUGHTER

GOODBYE, BROTHER

[music stops]

[sighs]

[sighs deeply]

Seo-hae, you have to promise me…

When you get there, you always put your own safety first.

Dad.

If you get into trouble, find me somehow, okay?

Okay.

You'll need lots of valuables so you can take the uploader.

You'll also have to pay the broker.

I heard the people have to make money so they can settle down there

by selling things like weapons and drugs that don't exist there yet.

But, Dad, that's…

This should be enough to get one person there.

What about you?

[leaves rustling]

[tense music plays]

[sighs]

How long have they been following us?

[Bong-seon] For two days.

[pants]

Your name.

Your name.

Seo-hae. Gang Seo-hae.

Why are you taking the uploader?

Answer me.

To prevent the war.

How?

I have to save one person.

Who?

Who?

Han Tae-sul.

Han Tae-sul?

-Tae-san. -[Seo-hae] Han Tae-sul!

Get down!

Han Tae-sul, get down now!

[suspenseful music playing]

[sighs]

It was you.

[dramatic music playing]

[music fades]

[dramatic music playing]

-[Tae-sul sighs] -Dad.

Dad.

This scar.

I got it when I learned to ride a bike with you.

When I was eight.

Uh, it's not that…

It's not that I don't believe you.

[sighs]

I'm sorry. It's all a little confusing.

[chuckles softly]

[chuckles]

You look the same as you did when you were little.

But you also look like…

You're gonna say that I look like Mom.

You've gotten a lot taller.

Your mom gave you herbal medicine and stuff to help you grow tall.

She'd be happy to see you like this.

Here. It's a bunker.

I still don't know who made it, or when,

but a war breaks out on October 31st.

You and I lived in that bunker for 15 years.

BUNKER UNDER THE BRIDGE

And Mom?

Mom…

[dramatic music playing]

If we knew that there was going to be a war,

why didn't we run away before the attack?

We can't.

People aren't aware of it yet,

but some people are banned from leaving the country.

If the Control Bureau doesn't want someone to leave, they get blacklisted.

You kept the promise that you made to Mom until the end.

You promised her you would never let anyone hurt me, didn't you?

Yeah, I got scratches here and there and hurt myself sometimes,

but that's because I didn't listen to you and went to places that were dangerous.

And somehow, I survived, and I'm here.

I think I know what's on your mind right now.

You wanna know why I came back here from the future?

You're sure you wouldn't have let me do it.

That's right.

You eventually let me go.

So thank you.

I did like you told me to and tasted fruit.

Not from a can but the real stuff.

I went to an amusement park and got to see my mother.

And the people I met here have been so much nicer.

They didn't try to steal from me like in the future.

They worried about me when I got hurt,

and they risked their own lives to save me.

I'm actually doing fine on my own now, and, you know…

I'm not alone out here.

I'm going to make sure nothing happens to those people either.

That they know nothing about the war

and just continue living their ordinary lives that they complain about every day.

I'm going to change things.

I can do it.

[sighs]

So when you're lonely,

pushing too hard, or exhausted,

look around for me and I will be there.

[Tae-sul sobs]

I love you.

[door closes]

Whoa, he's returned!

[laughs]

How does it feel to be back after wondering around the other world?

It feels great.

[inhales deeply]

I saw my life flash before my eyes.

[clicks tongue]

It made me think that I should be a good person after all.

You should probably give it a try sometimes if you get the chance.

Well, I've done one too many bad things.

[chuckles]

Tae-san…

Time to tell me what you did to him.

We have a deal, so tell me.

[Park sighs]

All right.

Your brother, Han Tae-san…

got caught by Sigma and was tortured.

He gave Sigma the key

and eventually told him where the safe was.

But Agnes was in the Control Bureau

and was able to get to Han Tae-san and snatch him

along with the key.

[scoffs]

So you're all in on this together, isn't that right?

All of you, Sigma, Seo-jin, and the Control Bureau?

We're not partners or anything. It's just that we're…

Well, it's business, all of this.

Anyway, I snatched him from Agnes again,

and I got Tae-san to make an exchange.

I told him to get that key

and keep it safe then bring it to me,

and I'll keep Han Tae-sul

safe from any possible danger.

So you told him to find the key

then, after the war, take the uploader and bring it back here.

Basically.

That first phone call, remember?

[Park chuckles]

Gimpo.

[Park chuckles]

[Park] Han Tae-san.

Did you bring the key for me?

[Tae-sul] Yes, I got the key.

[Park] Are all your limbs intact?

-[Tae-sul] Huh? -Are all your limbs intact?

Yeah.

Right. Your health always comes first.

Listen. We should get together. You can bring me the key.

[Tae-sul] Where should we meet then?

[Park] We'll come find you.

Where are you staying right now?

Um… I'm staying at a friend's place.

[Park] Hmm, a friend's place.

You said all your limbs are intact, right?

-[Tae-sul] Yeah. -Hmm…

Then let me ask you something.

What's the number on your right arm?

Hey.

[sneering] You're not Han Tae-san, are you?

Hey.

Come on, boy.

Go get him.

But then, Tae-san got captured, and Sigma had him again.

So Agnes figured that finally, after all that,

Sigma was still able to get the uploaded blueprints,

and that was the end of it.

So she just injected him, you know, well, with that drug.

-Why didn't you tell me all this? -She told me not to.

Anyway, the deal we had was that

Tae-san would bring the key to me

and I help you stay safe

both mentally and physically in return for it.

Well, that's all.

[footsteps approaching]

Oh, look who's back.

[chuckles]

So, is your dad out here?

Her dad sure has quite a temper there now, doesn't he?

I guess you get that from him, huh?

[Park chuckles]

[whispers] Let's go. This is not a good place.

[whispers] Oh, I still have some stuff to do here.

Hey now, what's this little whispering conversation about?

Look. I helped you save your girlfriend, so fix this.

Hey. You got a USB drive?

USB drive…

-[Tae-sul] Yeah, USB drive. -Oh, yeah. We have one.

[Seo-hae] What is it that he wants you to fix?

I did some messing around with his downloader.

[Seo-hae sighs]

[tapping on keypad]

-[phone chiming] -[sniffles]

[chimes]

[sucks teeth] Wait a second.

See, right now, you have very low credibility.

So how do I know that if I just hand this over to you,

you won't keep us here?

If that were my plan,

well, I'd just kill you all

and simply take it from you.

[Park chuckles]

Bingbing! Hey, get in here.

Oh, Seo-hae. You okay?

-[gun cocks] -You?

[sighs]

Not really. No.

Stand up straight.

Will you stop hitting me? Jeez.

You two, shut your mouths.

So…

[Park] Hmm?

It has a password on it.

God, you love getting fancy, huh?

Really? Hmm? Shoot his hand, would you?

-Hand it over. -Hmm?

Just hand it over. It's okay.

How's it okay? It's not okay.

I got it.

She said give it.

Oh… The password.

-Six… -[Park] Mm-hmm?

Nine, six, nine.

Well, those sure are nice numbers, 69, 69.

Bingbing!

See if it works. Hurry up about it.

[switch clicks]

So, is it working?

Come on. Hold on a minute. I just turned it on.

I haven't even stuck it in.

[Park] Just hurry up.

[computer blaring]

DOWNLOAD PROGRAM

[blaring continues]

It's working.

[chuckles]

So then, you can let us go now, right?

[sighs] Thank you so much for everything.

-[gunshot] -[Tae-sul] Shit.

Ah, shit! I knew you'd do this.

What the hell are you doing now?

We have some unfinished business.

I never planned on going to the Control Bureau,

but I did because of you.

That boy took a bullet and he won't be able to walk anymore.

Now, who is responsible for that?

How is it my fault? This is your life. You should blame yourself.

Hey, man…

[Seo-hae] You said the future was already determined.

So going into the Control Bureau and getting separated from your family

were going to happen anyway.

So are you gonna take your anger out on me now?

[chuckles] Take my anger out on her?

Yeah.

What infuriates me now is that everything I do

has already been determined.

That's what makes me angry!

[scoffs]

Does saying that make you feel any better?

You're saying that you can't do anything about it

so that you can't take the blame later if you fail to change it?

You're making an excuse in advance.

That's too bad. There's something I should tell you.

It's changing already.

[gunshot]

[Seon-ho] Seon-jae!

[tense music playing]

[Seo-hae] It was me who was supposed to get shot.

My diary said that I should prepare to lose the ability to walk

after being shot.

Here, for you.

It's Stem Cells.

What's that?

Stem cells. But it hasn't been developed yet.

You may not be able to change the future because you've gotten too scared.

It's changing in front of you.

So you can shoot me if you want.

Let's go.

-[screams] -[gunshots]

I can't do anything about it. Already determined.

That's what infuriates me!

[Sun] Whoa.

Seo-hae, you were so freaking cool back there.

How are you feeling anyway? Are you really okay?

Yeah, I'm fine.

Gang Seo-hae.

Is it true what you said in there? It was you who was supposed to get shot?

-So? -Why didn't you tell me?

Did you know that you were gonna be taken to the Control Bureau?

What else are you not telling me?

I don't know everything.

-Well, what do you know? -What's wrong with you?

What's going on? What's with you two?

Let go of me.

[breathing heavily]

[breathing heavily]

[dramatic music playing]

Seon-jae.

[Seon-ho breathes heavily]

[inhales deeply]

[gasps for air softly]

[chuckles softly] Are you okay?

[exhales sharply, groans in pain]

[sighs deeply]

[chuckles softly]

[crickets chirping]

Something happened before I came back.

I saw a grave.

It was my grave.

That's where I found my diary.

Then I touched something.

I've had a recurring dream since then.

What's it about?

Something's going to happen.

Time paradox?

Mm-hmm.

It's the last day, and we're in some kind of church.

You and I are dressed as bride and groom.

Somehow, I get shot.

Sigma tells you that you have to make a choice.

-[Sigma] Mr. Han Tae-sul? -Is this Sigma?

[Sigma snickers]

Is it the girl or the world? You can only pick one.

A choice between…

you and the world.

How'd you know that?

Sigma and I met

while you were unconscious.

What did he tell you?

He told me to make the uploader.

That's the reason I told you not to look for him.

He gives you only those two options.

-And last time… -I chose to make the uploader?

If you're put in the same situation again,

don't make the uploader.

Because either way…

I'll die anyway.

No.

It'll give us one more chance.

Everyone will die all over again.

And if I don't make it, what happens to you then?

[Tae-sul inhales sharply]

If there's never an uploader…

no one could come back from the future either.

-Then you would also-- -Promise me…

that you won't build it.

[dramatic music playing]

See that? It's money. Hmm?

I already ordered all the water.

When it gets here, put it in the basement. Here, I made a list.

Uh…

Oh, yeah, we need medicine and guns. Just get as many guns as you can.

Gas masks, protective gears, salt, sugar, canned food, chocolate. Got it?

What about ramyeon?

Ramyeon?

If they smell it, they'll swarm around us like a pack of dogs.

-Oh… -[Park] Oh, I almost forgot.

Jerky. Get a lot of jerky.

-I got it. Yeah. -You did?

We won't be able to leave here for a few months.

If there's anything we need, just get it.

Leftover money, just bring it to me.

-Where are you going? -Somewhere.

-Yeah, but where? -Just somewhere.

Now, make sure you get everything.

-[door opens] -[Seon-jae grunts softly]

[Seon-ho sighs]

-[Seon-ho sighs] -Hey.

Boss survived the war because he was in prison or something.

I heard him say it yesterday.

-I knew that. -Me too.

No way. You couldn't possibly.

Yeah, I did.

-What'd he do? -He killed someone.

Really? Oh, man. He's awful.

[scoffs] You knew that.

-Who did he kill? -No idea.

[sighs]

He doesn't really share much, does he?

[car door closes]

Yeah.

[chuckles]

It looks exactly the same.

[Jin-hui] I'm going to jump.

[sobbing]

-[grunts] -[breathes heavily]

Are you crazy?

[Hyeong-do scoffs]

Who's this guy sending three million won to you every single every month?

I told you, I don't know.

Are you cheating on me with this man?

What?

-You've lost your mind. -Lost my mind?

-[grunts] -[yelps]

-[scoffs] -[Jin-hui yelps]

What a freaking lowlife.

That asshole should get a job and work,

maybe not sit around the house and beat up his wife.

He's such a piece of shit.

[sniffles]

Get your act together, asshole.

[yelps]

[Hyeong-do] Who the hell threw that freaking rock at me?

If I catch you, I'm gonna kill you!

Bitch! This is all your fault!

[Jin-hui grunts]

What's up?

Nothing. Just getting some air.

I heard about what you did for me at the Control Bureau. It means a lot.

Hey, no. We're cool. Honestly, I didn't really do much.

I just ran around and was held hostage for a while.

I did get really scared there for a minute or two that we lost you.

Is what you said about the last day true or…

You were listening in?

No. I was just in the next room, and I overheard you.

Honestly,

I didn't understand all that stuff about the uploader, downloader, the war.

What… What if we just go abroad together?

Nothing will really happen, right?

I told you. I'm not going.

It's because of Tae-sul, isn't it?

Is there something between you two?

[sighs] I knew it. Oh, man.

Jae-sun.

[dramatic music playing]

[Seo-hae] Look over there.

What? The Hangang Bridge?

I lived by the bridge in a bunker.

Whoa. So you had a view of the river.

The river was dry, so no.

No way.

Everything you see over there will crumble and burn.

I'm staying because I want to,

not for somebody else.

Then let me ask you one thing.

What actually causes this nuclear war?

The nuclear bomb that Sigma sets off.

You said

-he came back through the uploader. -Yes.

Don't we just have to get rid of the uploader?

-Or can we just get rid of the inventor-- -Hey.

You've never been one to take the long way around.

You're always direct about everything else.

Hey.

You're into Tae-sul, aren't you?

-[Sun] Why? -It's not comfortable.

Wait. What are you doing? Why are you…

[Tae-sul clears his throat]

Oh, darn. I only have two cups of tea with me.

Do you want it?

Is he okay?

There's something I forgot to tell you before.

I told you I met Sigma, right?

Actually, I think I already had.

What do you mean?

Sigma asked me

if I remembered him.

I thought about it, how we might know each other, but…

-I can't remember him from anywhere. -[scoffs]

Or maybe he was just bluffing.

[sucks teeth] I don't know.

What's "bluffing"?

Hey.

Bluffing… It's a con.

Pretending like you got something really big when secretly you got nothing.

That's you. You act like you know everything when you really don't.

Hey, that's different. I really do know everything I'm talking about.

Oh, right.

[chuckles softly]

[dramatic music playing]

So…

Do I have to choose between the world and you?

I hate that stuff.

I never wanna have to choose between two things.

Whenever I order Chinese food, I just order it all.

Are you gonna keep rambling on?

Okay.

[inhales] Anyway…

[sighs]

I'm not even sure what I want to do.

I know I have to get rid of Sigma and prevent the war, sure.

But you'll disappear.

[Tae-sul sighs]

I'd hate that.

[dramatic music playing]

[sighs]

[Tae-sul inhales sharply] What could this be?

Do you think he knew that we would find where he was staying?

And this painting.

Do you think he left it there for us to find?

There's something strange about this painting.

Hmm? What is it?

Right here.

These buildings aren't there in the future.

[tense music playing]

[beeps, blaring]

[blaring continues]

SCANNING

And this is… Wait.

Hm?

[Seo-hae] This.

[beeps]

Wait a second. I've seen this before.

I didn't know why Tae-san was carrying these around.

I remember that painting from when I was a little kid,

and Sigma said that we knew each other…

so that means he and I have met before.

WOOHYUNG ELEMENTARY SCHOOL

HANKOOK UNIVERSITY

Do you think he's in there somewhere?

Mm-hmm.

[sighs deeply] We should check everyone's pictures then.

-Is it okay though? -Hmm? What do you mean?

Isn't this your embarrassing past?

[exclaims] How do you know about embarrassing pasts?

Who taught you that?

It was Sun, wasn't it?

-Sorry, what? -My past is clean.

I was born a perfect specimen.

[scoffs]

Sure. Clearly.

[Tae-sul] Oh, shit.

[Tae-sul smacks his lips]

Hmm?

What? Find something?

I…

This girl.

Back then, she had a little crush…

Yes, Song Ji-hye. She liked me.

Song Ji-hye.

[chuckles] She gave me a hundred frogs of origami.

She's pretty. Why don't you go and ask her to save your life?

Don't get jealous.

You don't need to worry about her.

What?

Hey. [clicks tongue]

Seo-hae.

You know what, listen.

[inhales sharply] So I've been thinking about it,

scientifically.

About that day.

About what the scientific implications of it are.

Everything that happened

while we were wandering around space and time

in a state of temporal displacement.

Although you can't really be sure,

I concluded that it was all quite real.

What are you saying?

On the shore…

we…

Hey.

That only happened because I thought it was the end.

Hmm?

It was a goodbye thing because I thought it was our last moment.

Okay, wait a minute.

[clears throat]

Is that how you say goodbye in the future?

So intimate. Are you American?

Or am I actually being too old fashioned with our customs here in the past?

-I thought you were single by choice. -Single by…

What does that have to do with this right now?

Do you even know what the meaning of "single by choice" is?

-Jeez. -Hey.

INTRODUCING MYSELF

DREAM JOB: A WRITER FAVORITE COLOR: PURPLE

Your favorite color is pink, right?

Why ask me that?

I mean…

Your diary is pink, your pistol is pink,

and all these tiny little decorative parts are also pink.

[sighs]

We only have 72 hours left before the nuclear war.

But these are the only things…

that I know about you.

I've wasted my whole life on meaningless stuff.

What have I been doing?

I'm running out of time now.

[chuckles softly]

My favorite food is bulgogi.

I already learned that in the sauna, at lunch.

Yours is tonkatsu.

What else? You should tell me at least three things.

Banana and…

Of course, my mom's tteokbokki.

Mm.

Favorite song?

"Spring Day" by BTS.

-Who in the world do you admire most? -My mom and dad.

And who's your favorite person?

[dramatic music playing]

Should I kill you now? Why do you keep asking these questions?

[exhales]

I just wanna remember.

[footsteps approaching]

Excuse me, can I help you?

You want to see the student records?

Please write down your name and the year of your graduation.

Oh, I didn't graduate from this school, so, uh…

Then you can just write the year that you started.

HAN TAE-SUL

-Han-- Han Tae-sul? -Yeah.

The Han Tae-sul?

Oh, my. I am such a huge fan!

You look so much more handsome in person.

[chuckles awkwardly] Thanks so much.

That's just…

My students are also big fans.

[chuckles] At our science drawing contest,

all the students drew pictures of you saving the day, fixing that plane.

They all want to be scientists now.

Really? [chuckles]

I thought you were just a brainiac,

but you're sweet and you have a nice body, too.

Wow, that's not something I've ever heard before.

[both laughing]

[scoffs]

What are you up to? Go on.

-Oh, class of '91. Could we see-- -Are you his girlfriend?

-Uh, no. -Yeah.

[woman chuckles]

I have to ask, would it be okay if I took a picture with you?

-Yeah, of course. Yeah. -Oh, thank you.

-Hmm. -[woman clears throat]

-Oh, you know what? -Yeah?

Can we not post it on social media? Privacy stuff.

-Uh, yeah. -It's just me.

I can't believe it. One, two, three.

[camera clicks]

Oh. Oh, my goodness. I'll get the records.

No, no.

Actually, is it possible for me to go look?

-Why? -Well, I'm, uh, sort of…

-I'm not really proud of my old pictures. -[woman chuckles]

-I know what you mean. You can go ahead. -Thank you very much.

-Where are the archives exactly? -Oh, end of the hall, second floor.

Oh, okay. All right.

[woman] Thank you.

[chuckles]

[snickers]

If you make any more noise, I will kill you.

[woman chuckles softly]

[computer beeping]

[U-jin] Han Tae-sul's spotted at one of our surveilled locations.

[keyboard clacking]

-The girl? -Confirmed on site.

Twenty minutes from here.

It's somewhere in here?

Yeah.

[Tae-sul inhales sharply, sighs]

STUDENT RECORDS, YEARS 1990-1995

[Tae-sul exclaims]

-What class were you in? -Class Four.

Hey. Hey, take it easy.

Let's just find it.

What's with you?

[breathes deeply]

"I thought you were just a brainiac,

but you're sweet and you have a nice body, too."

-What? You're getting upset about that? -You were pleased about it.

[scoffs]

Hey, I just needed…

I just needed to get on her good side to get us in here.

STUDENT RECORD, HAN TAE-SUL

[Seo-hae] Han Tae-sul.

"Gets excellent grades,

but everything seems to be a distraction for him.

He's self-centered and inconsiderate of his classmate's feelings."

Oh, well…

Is that what it says?

You haven't changed a bit.

"He's highly intelligent, but he lacks social skills."

"He barely participates in group activities and needs guidance…"

Hang on. Wait a minute.

STUDENT RECORD, SEO WON-JU

[Won-ju] Tae-sul!

Tae-sul!

Han Tae-sul! It's Seo Won-ju!

Hey! Han Tae-sul! Hey!

This is it.

It's him, Seo-hae.

[bully 1] You nasty cockroach!

-[bully 2] Eat shit, filthy cockroach! -[bully 3] Literal cockroach!

-[bully 2] Freakin' filthy cockroach! -[bully 1] You filthy cockroach!

[bully 1] Hey, you, you filthy cockroach. I told you to stay away from me.

[bully 2] Oh, gross!

What? Do you borrow your books from the library to spread your diseases?

[bully 3] Lord of the Flies? Why always read stuff like that?

It's freaking disgusting.

Look. He got it all over that book.

My mom says if you go anywhere near him, you could get rabies

because his dad sells lost dogs.

-Gross! You freaking cockroach! -You're gross you stupid cockroach!

[young Tae-sul] Rabies isn't transmitted from human to human.

Also, Lord of the Flies isn't about insects.

You haven't read it yet? It's a must read.

Who are you, dork, and what do you want?

His name is Han something.

-Han Tae-sul. -Oh, wait. You can talk?

You're just looking up at the sky all day,

so I thought you must be mute or something.

We'll leave you alone today because you're smart. Get lost.

I can't do that.

I'm the one in charge of the library this week.

I need to collect the borrowed books.

You're a freakin' orphan. You wanna get a beating?

[stammers] What's that?

Just some sodium and water. Mix them.

Mix them, go ahead.

[water pouring on flask]

[liquid hisses]

[bullies scream]

Before I blow up something bigger, get lost.

[bullies breathing heavily]

If you actually mix them together…

Teacher just told us in science.

You can't put them together because they cause an explosion.

[Won-ju] Thank you.

For what? I was just reviewing what we learned today in class.

LORD OF THE FLIES

It's overdue.

Bring it tomorrow.

[dramatic music playing]

[pencil rustling]

[dogs barking from a distance]

[door opens]

[Won-ju's dad] Dad is home! I'm home.

[Won-ju's dad sighs loudly]

-You little brat! -[grandma] Oh, he's asleep.

[Won-ju's dad] You don't even come out to greet me!

[banging on door] Get out of here!

[grandma] Stop this before you do something terrible.

-[Won-ju's dad] You little brat! -[Won-ju breathing nervously]

-[panicked breathing] -[Won-ju's dad] Hey!

[Won-ju's dad] Did you lock the door, huh?

Open up! [banging on door]

-Come, open the freaking door! -[rattling]

You little brat!

-Oh, God. Please, leave him alone. -Freaking little insect! Get up!

-Get off of me! -He didn't do anything wrong!

I'm gonna kill you today! Huh?

Hey, what's that?

Tae-sul, I think, in the future, you're going to be someone great.

Why are you saying that?

I can see into the future.

All the things I see, I draw them, and they come true.

I saw it. You're going to save the whole world.

It will happen.

[dramatic music plays]

-Come on. Let me see. -No, just stop it.

But you're always making drawings in here.

-This is not a drawing. -What is it then?

-A diagram. -A diagram of what?

-A time machine. -A time machine?

Ah, time traveling.

Mm-hmm. Right now, I can't build it.

I'm going to do it when I'm an adult and can actually do it.

Oh, so you can go to the future?

Oh, no. Just back to the past.

Why? You know everything in the past that already happened. That's not fun.

I want to go to the past.

Tae-sul.

So, if you are really gonna make a time machine for us both,

can I be the first one to ride it?

-Damn it. Seriously. -[sighs]

-[bully 1] This sucks. -[bully 2 sighs]

I'm gonna kill you if I run into you again.

-You're so stupid. -I hope you get struck by lightning.

-He's so stupid. -How annoying.

-I hate him. -Come on, let's go.

Let's get out of here.

-So no one is bullying you these days? -No.

-Good for you. -Yeah.

By the way, how did you get all bruised up like that?

What?

So, hey…

Can you teach what you did the other day? The explosion.

-Why? -Huh?

Oh…

How do you make that possible?

Water and…

Sodium.

Is there somewhere you can buy it with money?

I'm not sure. There's a lot of it in the science room, covered.

[snickers]

[dogs barking]

-[Won-ju's dad] Open up. -[door rattling]

Open up the freaking door, boy. Open it! Open it before I break it down.

You're gonna regret this later.

You little brat.

I'm not gonna have you choose to ignore me when I wanna talk to you.

-Open up. Open this door now! Hey! -[sizzles]

Open it now, you little brat.

[Won-ju's dad grunts] Hey! I'm gonna kill you!

[glass shatters]

[male teacher] Seo Won-ju.

Seo Won-ju.

Class, is Seo Won-ju absent?

-Han Tae-sul. -Yes?

-You're close with Won-ju, right? -Uh, no.

The two of you are always going home together.

Well, he just follows me.

[door opens]

Mr. Lee.

[softly] Go on. Let's go.

Students, stay here. Work quietly.

[children clamoring]

[bully 1] Guys. Guys, come here.

So, did you hear?

My mom said there was a fire at the house of the rabies kid.

There was a… [imitates explosion]

[bully 1] You didn't hear the explosion?

-[bully 2] Really? -[bully 3] Yeah.

They say his grandma and his dad both died.

All their dogs burned to death.

-[bully 1] Really? -[bully 3] Yeah.

I can see into the future.

All the things I see, I draw them, and they come true.

[bullies] Boom!

[eerie music playing]

[Won-ju snickers]

It's so quiet now.

It's so quiet. It's so nice.

[Won-ju snickers]

You. What did you do?

You taught me how to do it.

I did the same thing you were doing.

Go away. Just get back.

The police. I'll tell them what you did.

Why?

I did the same thing you did. Why is it okay for you but not for me?

You told me to do that!

No, I didn't! You're a psycho! Go away!

[scoffs]

What did you say?

I don't wanna be near you. You better go.

[scoffs, snickers]

[laughs maniacally]

Now, look…

You're just like all the other kids, huh?

[snarls softly]

I am going to kill you all.

[tense music playing]

He said he wanted to be the first one in it.

In what?

The uploader.

[loud bang]

ARCHIVE ROOM

[both grunting]

-[both grunting] -[glass shatters]

[screams]

[grunts, groans]

[grunts]

[yelps]

[both grunt]

They were expecting us.

[glass shatters from a distance]

[Sigma] Tae-sul! Come out and play!

Tae-sul! Come out and play!

Han Tae-sul!

What a psycho.

[Sigma] Come out and play!

Han Tae-sul!

[tense music playing]

Tae-sul! Come out and play!

Tae-sul! Come out and play!

Han Tae-sul!

["Stay (tempus)" by GSoul playing]

[Tae-san] Seo-hae.

There's something I've always wanted to do at a time like this.

[Eddy] You guys have any idea what kind of frenzy is out there now?

Tae-sul did this by himself.

Tae-sul, don't fight him.

You can't beat Sigma.

[Seo-jin] It's like a gathering

of the people who control this country as they wish.

[Park] They all came back from the future. They were the first.

-Seo-hae, no. -[Park] This is exactly what he wants.

You're playing right into his hands!

We'll have another chance. Let's just go right now.

[Seo-hae] There won't be another chance.
