WHEN THE STARS GOSSIP

Guess which creatures currently dominate the population on the space station.

Topping the list are 30,000 fruit flies,

with 80 mice coming in second.

The real owners of the space station, which can house up to nine astronauts,

may be fruit flies and mice.

Since humans and mice share 85 percent of their genes,

studying mice in zero gravity

provides a glimpse into how humans might adapt to space.

Most of human gene functions have been discovered through studies on fruit flies.

As you can see, the reality of the space station is quite different

from what we might imagine.

Let's hear more from Chief Kang Tae-hui at the Seoul Mission Control Center.

The space station's zero-gravity environment

enables experiments that can't be conducted under Earth's gravity.

The space station's true purpose is

to study how the human cardiovascular, musculoskeletal,

neuroendocrine, and immune systems are affected in space,

using fruit flies and mice for testing.

The Expedition 3 team, which recently embarked on their space mission,

is ready to break new ground once again.

Here's an interview with Commander Eve Kim of Expedition 3.

Our mission is to attempt mating, pregnancy, and breeding in mice again.

Fruit flies, minnows, and cockroaches

are the only species to have successfully reproduced in space.

Mice, like us humans…

Sir, they'll be docking soon.

…have never mated,

become pregnant, or given birth in space.

For humans to sustain life

and reproduce in space, mice must first succeed in breeding.

Now, what's the mission of the space tourist

who paid a whopping 70 billion won to join them?

G.O-10, approximately 400 meters until rendezvous.

Copy.

Copy.

Initiating the fly-around.

Onboard navigation is working fine.

Standing by for contingency manual docking. Over.

Copy that.

Rotation is nominal.

Engine operation, normal.

150 meters to the ILS.

Changing direction from the Kurs antenna to the docking point.

G.O-10 approaching the ILS.

Stand by for contact.

All right, we're about to dock now.

- Engage your core, sir. - Okay.

Checking the crosshair alignment.

Contact?

Crosshairs are not aligned.

Oh, man.

Stand by for manual docking.

Come on, man.

Contact?

G.O-10 retrying for the alignment.

Five feet.

Three.

Two.

One.

Target in the center.

Here we go, G.O-10. Yeah.

Good boy.

This is IOU. Contact and capture confirmed.

Docking…

complete.

Contact and capture confirmed at 16:20 central time, 17:20 eastern time.

Two vehicles are flying high above the Pacific Ocean,

just to the west of Peru.

They have finally docked successfully.

It's on.

It's on! The doping was successful!

It's "docking," okay?

Oh, thank God in heaven.

Victory!

Leak test, complete.

Both docking area completely sealed.

Perfect!

Nice.

Docking area sealed, okay?

Station IOU and Spaceship G.O-10,

you have a go for Step 6.

Ingressing ILS.

Finally, the space station.

Commander, I'm nervous.

I told them several times to make it longer!

It gets tight in my crotch in zero gravity.

I grow taller here.

- You haven't knocked yet, have you? - Not yet.

All right. We'll knock on our side first,

and if we hear them knock back, it means the docking was successful.

Santi, lead the way.

No, you got it.

We don't have all day, Commander.

EVE: COMMANDER OF EXPEDITION 3

Okay.

When they open the hatch and enter, it'll be broadcast live worldwide.

Let's make sure not to touch this part.

Okay.

Our voices won't be broadcast to Earth, right?

Will they?

Ready?

Wait.

- What is it? - Hang on.

Me too.

What's that?

I know better than to show up empty-handed

when I'm invited to someone's house.

What on earth is it?

It's a housewarming gift.

Let's open her up, Commander.

Ready?

What's up?

We are not the only ones here.

What?

When did these guys get on?

Did a couple of fruit flies sneak on board and travel here from Earth?

Can you believe these guys?

I paid 70 billion, and they got a free ride?

Hey, how much did you guys pay?

No! Stop it.

It's a miracle they're here. Don't kill them.

No, don't.

You can't just sneeze them out.

Use your words, will you?

They can't understand me.

Did you just hit me

to get back at me for stitching up your toes without anesthesia?

Shush.

They're not some test subjects that were pumped full of drugs to get here.

They're the first living creatures to come to space

on their own, sitting on a banana.

Santi, go buy some time. Go!

- Eve. - Go!

What's the holdup?

What's going on?

Why aren't they opening it?

What are they doing?

Hey, where are you going?

The male was chasing the female, and now he's finally sitting down

and licking her butthole.

They're about to mate.

What's the big deal about a stupid fruit fly chasing after a female

and leaking her butthole?

You slapped me for that?

Don't you see? These guys are doing something even humans can't do.

They're creating life in space, which is incredible.

Look at that.

The male is flapping his wings…

Oh, my God. Do you see how he's making noise with his wings?

He's trying to impress the female with everything he's got.

Gosh, it's so noisy…

I've got to observe this. Wait.

Don't touch them, okay?

Touch them? I'm not doing anything.

Hold on a minute, guys.

Look.

The male is holding the female with his front legs

and bending his abdomen like this. Can you see it?

You have to see this. Come on!

Wow, come look!

Oh, my goodness. Look at that.

Oh, gosh.

Hold it like this, Dr. Gong.

You see it, right? Can you see it?

- Oh, I can see it. - Right?

That's risqué.

All right, okay.

- They only need 20 minutes. - What? 20 minutes?

They last longer than humans.

Quiet.

Wait, fruit flies can keep going for 20 minutes?

On Earth, they risk getting eaten by dragonflies

and still manage to go for 20 minutes.

They literally put their lives on the line.

And look where we are now. We're in space.

They're doing it in space, all right?

This is

an incredible moment where they're creating life.

They're doing something that mice,

which represent all mammals, have never succeeded at

in zero gravity, let alone humans.

We have to wait for them to finish.

We absolutely do.

Eve.

- Yeah? - Let me get this straight.

So you want to make everyone on Earth

wait 20 minutes for these fruit flies? Is that it?

You're just…

You're really enjoying this.

Just look.

They're going at it.

You got this!

That's it!

EXPEDITION 3 DOCKED

It seems the hatch hasn't opened yet.

As soon as it does, we'll connect with the Mission Control Center

and bring you the live feed.

We at MZ Group, a leading global enterprise

that delivers new value with cutting-edge technology,

carried out the 2023-MS-01 Project through our MZ Central Research Center,

which is equipped with proprietary technological expertise.

Let me start by briefly explaining the products.

What the heck is taking so long?

Right. I'll make it quick, sir.

The first one is a cooler.

It weighs 950 g and is made with…

- …the third to enter. - What's taking so long?

- Once he does… - He's in space.

…he will have the honor of becoming the 458th visitor.

Fruit flies?

What in the hell…

They're not even official test subjects

but just some stupid flies that hitched a ride. Are you telling us

to delay the docking and wait for them to finish their business?

Are you insane? This is a big moment.

Tell her to open the hatch right now.

With all due respect,

they are doing it on the knob

right now, so opening the hatch would effectively

kill the mood.

So, I mean, we could not do it,

and maybe they would run into a wall or we would step on one of them…

But this is a pleasant surprise, so…

I guess all she needs is 20 minutes.

You think this is funny?

Eve, that goofball. Just when you think she's doing great,

she pulls this crap.

She's got a knack for driving you up the wall.

Come on, the flies are making love.

Why are you here? Go start your new, better-paying job.

Get out!

Listen, make sure no one talks about the fruit flies on air.

How about they open it from the other side?

No, right? That's never happened.

What's going on?

Should we just open it?

I don't think it's ever been opened from this side before.

I thought you were the type to never break the rules.

In space, there's no rule

more important than protecting and creating life.

Even though they only live for 50 days, fruit flies are no exception.

- Eve. - Call me "commander."

Why?

I like your name. It reminds me of Christmas Eve.

I hate Christmas Eve more than anything.

Commander.

Let's give these guys some names.

This is a remarkable twist of fate.

They risked their lives to come all the way to space with us.

For the male, how about…

Public?

- What? - And for the female…

Indecency.

- Are you joking? - I'm not joking.

Public and Indecency. I think they're the perfect names.

Forget it.

Public and Indecency. I like it.

That's not what they were doing.

That's exactly what it was.

- Sir. - For God's sake, stop calling me "sir."

I hate that.

Don't you think you're too fixated on those flies?

That slap across my face was a clear sign.

Nothing better comes to mind?

It's settled then. They're Public and Indecency.

They're not your pet flies, sir.

Eve.

- Eve? - Call me "commander."

You're awesome.

Call me "commander."

Eve.

Eve.

MCC, it is taking a little longer

than anticipated to seal the deal.

The large MZ Confectionery logo adds promotional potential as well.

Why won't they go into the space station?

What if the ice cream melts?

Won't it be game over?

Yes, it's all over if it melts.

Is there something wrong?

What if Ryong was scorched by that lightning from earlier?

Come on, don't say that.

It's not easy to get hit by lightning.

Our team is coordinating with the control center

to check if there are any issues.

We'll update you as soon as

- we have more information. - Na-mi.

Our son can't marry the heiress unless he risks his life in space, right?

Otherwise the chairman won't approve?

Come on, Ryong said that wasn't true.

Of course it's true.

The chairman still hasn't given his blessing because of us.

His three moms work at a bar.

Would you like that if you were the chairman?

- We've just been informed… - Ryong is coming out.

- Oh, he's coming out! - …the hatch is about to open.

- He's coming out! - We'll switch to the live feed.

All right, everyone. The hatch will now open.

HATCH OPENING LIVE

Here they come.

This is Mission Control, IOU.

Official hatch opening time for G.O-10 spacecraft, 22:35 UTC.

Mina!

- We've been eagerly waiting for you guys! - Come on.

Let's go.

Commander.

Do you like babies?

Babies. Do you like them?

Who doesn't like babies?

All right, then.

Hola, buenos días. Hello.

Hi to everyone.

Ho, ho, ho. Santa Claus came early this year.

Got you guys a special delivery.

A little something, something.

Ta-da!

Wow, you guys are more excited to see those guys than to see us guys.

- You can tell? - Well, no kidding.

Hello, everyone.

Hey!

How have you been?

Eve! I missed you!

Long time no see.

If I can just get used to this zero gravity, I can pull it off.

I've practiced a million times.

I can totally do it.

Everyone, this is Mr. Gong Ryong, the tourist.

Say hello.

Oh, hello.

Hello.

Hello.

I… I'm Gong Ryong.

But why is our Ryong the only one flailing like that?

…but he certainly looks excited.

SPACE STATION ARRIVAL

I have no idea what's going on over there

because I can't hear them.

Look closely. See if he's okay.

Starting on the 6th, Mr. Gong Ryong will spend 10 days…

Our boy looks handsome.

There's no one better.

No one even compares.

He made it. It's all good.

Well done, baby.

Great work, everyone.

- Great work. - Good job, everyone.

- Good work. - Thank you.

All right, I'll be leaving now.

Are you crazy? Don't be absurd.

What? Why?

Look at you. You all look taller,

and your skin looks younger than when I saw you on Earth.

Doesn't this zero gravity

make me look at least three years younger than Dona?

Maybe you're right.

It even straightened out Santi's misshapen sperm two years ago.

So, how long did it take to get back to your original state?

Oh, gosh. It didn't even last on my way home.

I wish I would've shown my wife.

I feel like every time I reenter the atmosphere,

I get wrinkled.

Zero gravity is both a blessing and a curse.

I'm sorry.

By the way, did you come empty-handed?

Where's the thing I asked for?

But why would you of all people…

Is this what you wanted?

Yes, okay.

You have to share your fruit fly pregnancy experiment with me now.

All right.

Are those lottery tickets?

Did you get one for all of us?

Hey, we can all watch the numbers together tomorrow!

But Dr. Kang, what's the point of you winning the jackpot?

- You already have more money. - Oh, sorry.

That's not my money. It's my father's.

You okay there?

Yeah, I'm fine.

Actually… I also brought a gift.

Regalo.

Following tradition,

the astronauts who just arrived are having a welcome ceremony

with the three astronauts already residing…

Father, I think

there might be a way to give you a grandchild.

Is this

really possible?

Your body is compressed and distorted by gravity on Earth,

but in space, it returns to its natural state.

The spine stretches, making you taller, wrinkles smooth out,

and even the telomeres at the ends of chromosomes lengthen,

all thanks to zero gravity.

Astronaut Santiago says in that report that his crooked sperm became straight.

It's similar to Dong-hun's case.

- So then… - There's a chance

Dong-hun's sperm will regain normal function in space.

Once restored, we can inject them into my eggs

and create an embryo through IVF.

We should try it right away.

Who should we send up there?

Send Dr. Gong Ryong into space.

What's that?

Ice cream?

How did he know they go crazy for ice cream?

You miss that soft, melting sensation up there.

They don't have anything like that.

That's a nice touch.

I bet he's trying to promote MZ Confectionery ice cream.

It's a PR stunt.

No one has ever taken human eggs up to the space station, sir.

How will you keep the eggs frozen and sneak them in

without declaring them?

When they tested human sperm before,

it was only to check the astronauts' health.

The IOU would never allow

human life to be created in space!

If I get caught, I won't be the only one getting punished.

It'll ruin MZ Group, your entire business.

Isn't sperm often sent up to space for experiments?

I'll have Dong-hun's sperm sent there on a cargo ship in advance.

All you have to do is sneak in the eggs.

If you manage to create an embryo using Dong-hun's sperm

and bring me a grandchild,

I'll seriously reconsider your relationship with Go-eun.

No, forget it. I can't.

Hey!

I'm not asking you to kill someone or steal something, am I?

Min-jeong wants to be a mom, and I want a grandkid.

You're not considering our feelings.

Are those stupid IOU rules more important to you?

Go-eun can't have kids either.

You ended our family line, so you need to take responsibility!

I ended your family line? That's ridiculous!

I'll let you marry Go-eun.

Even if you offered me your entire fortune, I wouldn't go.

I mean, I can't.

And don't try to use a child as leverage.

You can't make deals with human life.

Come on, kid!

If you have to go through with this,

get an ICSI specialist instead.

The procedure needs to be performed

by a specialist, not an ob-gyn.

There are plenty of great ICSI specialists at the MZ Medical Center.

Look.

Who am I supposed to spill this huge secret to?

You're board certified for ICSI.

You got certified in the US.

Come on, we're family.

I'm trusting you with this because you'll join my family soon.

Who else could I trust with something this big?

I told you, I haven't done it even once since coming back to Korea!

You're the only one I can ask.

I should give up?

I became a pediatrician because I love kids.

I even got married to have my own children.

Now that I know there's a way,

how do you expect me to just give up?

You're the one who told me to keep trying without giving up.

Dr. Gong, why can't I hear the thing

that you've said a million times?

"Congratulations

on becoming a mother."

That's the best thing I could ever hope to hear.

Please let me hear it too.

Ta-da!

Which flavor would you like?

I'll take strawberry.

Oh, but…

Oh, come on. Strawberry is…

Give me one too. Me! I'm next.

For you, Ms. Mina Lee, almond.

Thank you.

For you, Mr. Lee Seung-jun, chocolate.

Wow, thank you.

Now, Santi, you get cherry.

KANG-SU: SLEEP MODULE EVE, GONG RYONG: KITCHEN MODULE

MINA: OBSERVATION DECK

SEUNG-JUN: AIRLOCK 2

SANTI: OBSERVATION MODULE

Commander, you get mango.

I'll have vanilla.

So this is my gift to you.

I picked them according to your tastes!

Did you declare all that?

Declare?

Oh, why is she dragging it out like that?

I mean, what if he gets caught?

Once you're done, tear off the bottom.

That's the secret space.

I'll put the eggs under the vanilla ice cream.

Yeah, did you declare it?

The personal privilege kit is the only storage assigned to you.

It's small,

and you have to pay by the weight.

You're the first tourist

to fill that expensive, valuable space with ice cream.

Of course I did.

Right.

Then can I have the vanilla?

What? No, I…

Hey! Wait, that's…

The commander just took the vanilla.

Oh, no.

The genius scientist who was nominated for a Nobel Prize.

Dr. Lee Seung-jun, studying Alzheimer's in mice.

DR. LEE SEUNG-JUN THE SCIENCE PRODIGY

STEM CELL RESEARCH FOR ALZHEIMER'S DISEASE

Twenty-nine.

Thirty!

Mina Lee,

twin sister of Dr. Dona Lee from MCC.

A doctor of astrobotany.

They're studying the differences in human aging and diseases

when one twin is in space and the other is on Earth.

Santiago González Garcia,

a Spanish veteran astronaut.

This dangerous project started

because of his report on his crooked sperm.

SANTI, ASTRONAUT AND FORMER MEMBER OF SPANISH AIR FORCE

RESEARCH ON ABNORMAL SPERM IN ZERO GRAVITY

Kang Kang-su,

Mr. Selfish Gene, Go-eun's ex-boyfriend.

He's the heir to a global bank with more branches

than fruit flies in the world.

He's battling fruit flies to ensure long, healthy lives for people on Earth.

KANG KANG-SU, INFERTILITY AND RARE DISEASES

Eve,

a mouse expert aiming to achieve mouse pregnancy and breeding in space.

Wait, the vanilla is mine.

Commander!

Commander, come on!

The mission commander in charge of the space station this year.

It's her duty to question

every little detail to ensure the station's safety.

EVE KIM, EXPEDITION 3 COMMANDER

MOUSE BREEDING AND HUMAN SURVIVAL

Hey, give it back!

I… I can't eat mango!

Hey, give it back.

Give it back! That's mine!

Why are you obsessing over this?

You're the one who's obsessing, not me.

I asked you if you declared this.

How many times do I have to tell you? I did declare it.

I told them I was bringing ice cream and paid for it too.

They opened each one

and checked what was inside.

Just ask the IOU or the Mission Control Center

and save me the trouble, okay?

You declared five cups of ice cream.

There are five of us on the space station crew, including me.

So you brought five housewarming gifts.

That's fine.

But with this vanilla ice cream, there are six in total.

One of them…

is for me.

It's for me.

What? I don't need to declare the one that I'm having, do I?

I put one more tiny cup of ice cream for myself

in my personal storage, which I paid for.

Should I just sit and suck my finger while you eat?

Why are you treating me like some kind of criminal

just because I brought an extra one for myself too?

If it's not declared,

you can't bring anything up here, even if it's a gift.

You have to pay by weight for your personal items, right?

It costs over 100,000 won per gram.

So this one cup of ice cream is worth over ten million.

Why would you spend that kind of money on us?

You paid 70 billion to come,

so you're entitled to enjoy your money's worth.

So why are you trying to win us over?

Why are you buttering us up?

You're acting suspicious.

Is this some kind of drug?

Why didn't you declare it?

Did you bring some dangerous substance

to mess up our experiments or something?

If so, come clean.

Did you bring some frozen poison

to harm us astronauts? Is that it?

Look.

I'm a doctor.

I save people's lives. That's what I do.

Do I look like someone who's here to harm you people?

I'm even more suspicious because you're a doctor.

What?

What is your problem?

You're familiar with drugs.

Let me eat it and prove it, then.

I'll eat the ice cream, and that will prove it, right?

If there's really poison in it,

I'll die if I eat it. Problem solved, right?

Give it to me.

Come on, give it! I'll just eat it and die right here.

Let's melt it and see what you've hidden in here.

No!

Don't move.

That 70 billion wasn't even his money. His girlfriend paid for it.

All he has to do is snap a few pictures up here with her company phone.

Must be nice.

So is the tourist marrying the heiress or not?

Apparently, he even quit his ob-gyn job to marry her.

What?

It's nothing.

They say he's just after her money.

He's pretending to be in love with her and even came to space for it.

Everyone's talking about it. He's ambitious.

What is it? Tell me.

Don't worry about it.

Does Eve know?

That's why she was against him coming along.

Come on, I want to know. Please?

We're just gossiping.

You don't need to know.

Fine.

Hey, wait!

Keep still.

My ice cream.

Where are the spoons?

Oh, here they are.

Let's eat.

I'm sorry I suspected you.

Hey, is it good? Let's share it.

No, not with someone so scary!

Come on, just one bite.

Hey, don't eat it all. Let me taste…

You finished it?

You're kidding.

It's just vanilla.

No! Don't…

This is the important part.

In space, you need to reduce

the size of your trash like this, okay?

Now, come here.

It says "trash" here, right? Put the trash in,

and make sure you seal it tight, got it?

Otherwise, the trash might float back up.

I will never forgive you.

I hope you enjoy your stay here.

Enjoy my stay? Are you kidding me?

Just move.

Why are you so worked up?

What do I do?

- What do I do? - Oh, and…

You'll hurt yourself if you keep flailing like that.

We all once lived in the amniotic fluid of our moms' wombs.

Imagine this is your mom's womb.

Don't fight zero gravity. Just relax,

and try to move naturally like a fetus.

You'll get the hang of it.

What the hell is she talking about?

Wait, what?

Shoot.

What?

Shoot.

Are you sure?

Yes, I'm sure.

The eggs seem healthy.

All right!

We're good to go, then.

I've got the eggs now,

and I also got Dong-hun's sperm

from the cargo ship and stored it in the portable freezer you sent.

I'll proceed as scheduled.

Sir.

What's going on here?

Dr. Kang has the eggs?

Why is he doing what Ryong was supposed to do?

Ryong did a good job with the delivery.

Tell him to enjoy the tour.

Dr. Gong knows my eggs better than anyone.

He has to be the one to do it.

What do you think that clown can do in zero gravity?

Come to your senses!

Darn it.

Which way is it?

Guys, where are you?

Where are they?

GO-EUN

Hey, Go-eun.

Ryong, hi.

I'm looking for it.

I'm on my way to check the other ice cream cups.

Don't worry, I'll find it.

I'm sorry.

Why are you apologizing?

Listen.

You're just a delivery man.

My dad tricked you.

Your job was just to deliver the eggs to the space station as a guest.

Kang Kang-su will do the fertilization.

- What? - That was the plan all along.

My dad lied to us.

Who?

Your ex-boyfriend?

That Kang Kang-su?

Mr. Selfish Gene?

What do we do now?

Are you talking about that fucker?

Hey, Eve.

A grumpy male mouse is having trouble adjusting.

Are you talking about Male Mouse 1?

Yeah.

He was the sweetest one back on Earth.

Is zero gravity too much for you? What's wrong, buddy?

Hey.

How's the tourist handling zero gravity?

Well, he'll probably get the hang of it just in time to leave.

Oh, right.

Listen, I rushed out of the house and left my TV on.

Could you send someone to turn it off?

- I don't want a crazy electricity bill. - Okay.

Don't worry about it.

Just make sure you get a mouse pregnant this time.

Let's win the Nobel Prize.

What are you still doing here?

Don't you need to go pack your stuff?

Your junior was offered a great job,

so why are you being so jealous? It's so obvious.

Do you want me to stay?

- Would you? - What's the matter? Everything looks fine.

Of course not, they're paying me more.

Exactly.

Dr. Kang Kang-su also got board certified for ICSI in the US

when he was a postdoc in biology.

Since he's already used to zero gravity, he obviously has an advantage.

I didn't think of that.

I'm sorry.

I won't let this slide.

I'll turn everything upside down.

The chairman clearly has no intention of letting you marry Mr. Gong Ryong.

Ryong must be…

feeling terrible right now.

Hey. Give me that!

Stay out of it.

I'll take it from here.

You can't take this away from me like this.

Who do you think you are?

What are you, a thief? Aren't you ashamed of yourself?

You were a delivery man from the start. Nothing more, nothing less.

Damn it. Kang Kang-su, you little…

I am her doctor, okay?

You can't change a patient's doctor without their consent.

You've never even seen her eggs.

You've never stayed up all night trying to figure out what's wrong!

Those are her last eggs, okay?

I know them better than you.

I have to be the one to do it! Give them back now!

Bring my child back to life then.

- What? - The child that Go-eun and I lost.

The one who barely had any time in this world. Bring back my child,

and I'll give you the eggs.

Look. Both you and her father

act like I'm a murderer or something.

Go-eun's condition was more critical than you would think.

You don't care what happens to her?

You want to marry an heiress?

Are you delusional?

Just give up while Mr. Choi is being nice enough to send you to space.

I didn't come here as a tourist.

- Zero gravity is no joke. - I prepared for over a year.

In zero gravity?

I've been working on this in zero gravity for over a year.

Can you handle a microscopic needle better than me?

Look at you now.

How the hell would you precisely inject the sperm into the egg?

Give it up.

Go-eun is mine.

Eve, if Male Mouse 1 is still not adjusted by tomorrow,

should we try some medication?

Yeah, I'll check on him overnight.

You must be tired. Let's get some sleep, guys.

Good night.

This is your first night. Good night, you two.

You know how to sleep in here, right?

Don't just float around here like a corpse all night.

Okay?

When will I get used to

this stupid zero gravity?

By the time you go home?

Why didn't you just shoot me earlier?

It's not too late now.

Do it. Shoot me.

Come on, I said I'm sorry.

I can't keep apologizing. Accept it or not, it's on you now.

You live in this dump?

I'll do it on one condition.

What is it?

I told you, I'll do anything.

It can't be just about your grandchild.

I'm risking my life to go to space,

and I won't do it just for your grandchild.

If I succeed,

share the results.

I want MZ Group to build a fertility clinic in space

so other people in desperate situations can also have children.

A fertility clinic? Who are you kidding?

Just be honest and tell me you want to marry Go-eun

and live in comfort, kid.

We're talking about my life here.

If I'm going to risk it, it should at least be for something like this.

Fine.

Fine, I'll do it.

Chief!

GONG RYONG'S 2ND DAY

Oh, God. What the… What's that?

What's happening?

Male Mouse 1 started biting through

the tails of Female Mouse 2 and 3 in the same cage.

Within minutes, he devoured their legs

and started gnawing at the bars with a bloody mouth.

Look at him all messed up and covered in blood.

He's just like you, no?

This is you.

It'll probably die soon.

I did a thorough check just to be sure.

I found signs that Male Mouse 1 attacked

the females in another cage too, biting their bellies, legs, and necks.

I get that the zero-gravity experiments can be stressful,

but we can't just let him be.

What do you mean?

If we do, he'll kill all the other mice too.

What then? Are you saying we kill him?

We should put him down. Each mouse costs over two million won.

We can't do that.

The mice are what we send on the cargo ship the most.

What if they all die? We send another one?

Think about the cost!

Let's stick to their policy.

You're a scientist. If you get so emotionally attached to a mouse,

we can't do the experiments efficiently.

You need to remain objective as the commander.

This is a test subject.

Just Mouse 1. It doesn't even have a name.

Commander, let's stick to the policy.

If we don't find a solution,

we'll have to keep putting them down like this.

Please give us some time.

You're wasting resources and time.

We're here to figure out how we can all live here together.

No, Mouse 1!

Mouse 1 is having a heart attack!

Good.

Let's just get back to work.

- Dr. Lee. - Let's do it.

What are you doing?

Hey! For God's sake…

One, two, three, four, five.

One, two, three, four, five.

What are you doing with a dead mouse?

One, two, three, four, five.

Come on. One, two, three, four, five.

One, two, three, four, five.

Shouldn't you go harder?

No, that'll rupture his heart and blood vessels.

One, two, three, four, five.

One, two, three, four, five, six, seven, eight, nine, ten.

What do we do?

It looks like he's gone.

I got a cramp.

I'm fine.

One, two, three, four, five.

Let's open up his chest.

I've never done an open-chest cardiac massage on them.

I've done it on a newborn baby.

One, two, three, four, five.

One, two, three, four, five.

Dr. Lee.

Hold Mr. Gong's legs with Santi so he can stand still.

Come on.

- Show me the glove box monitor. - Yes, Chief.

Could you hold me a bit tighter?

All right.

Scalpel.

Scissors, please.

Okay.

No, not that one. The one on the far left.

The far left?

Okay.

Commander, get the retractor in.

Oh, his vitals are dropping.

Give him three micrograms of epinephrine.

- Come on. - Hurry, there's no time.

You're out of your minds.

All right, relax your body. Relax.

Okay.

Come on.

Come on.

Gently.

You're scientists.

You've got to be kidding me.

What the hell are you doing with a tourist?

You have no idea what you're doing.

Enough! Shut it, for God's sake.

His breathing seems to have stabilized,

but his heart still won't beat on its own.

His heart is so small.

I'm not sure how much pressure it can take.

His breathing is getting weaker.

Commander, maybe we should let him go.

No.

You've done everything you could. He's in pain.

No.

They shouldn't have bothered.

No.

Look at him all messed up and covered in blood.

He's just like you, no?

This is you.

He'll probably die soon.

Commander.

Switch hands and start compressions.

Let's clamp the aortic arch.

A mouse is just like a human, only smaller, right?

Okay.

One, two, stop. Again.

One, two, stop.

Again. One, two, stop.

One, two, stop.

Again. One, two, stop.

What are they doing?

It's what they'd do to a human.

By applying pressure on the aorta,

they can make sure the blood circulates throughout the body.

One, two, stop.

- One, two, stop. - One, two, stop.

- One, two, stop. - One, two, stop.

His heart is beating!

He lives!

Oh, it's beating.

His heart is beating!

His heart is beating!

- You're okay now. - He's alive!

He's alive.

Si-won, get this on the news.

Okay.

Oh, I knew it.

Listen, Male Mouse 1 had a mate back on Earth.

Wait, what? Is he alive?

He's alive?

I'm so glad! Hang in there.

There's a reason Mouse 1

only attacked the females, not the males.

He was missing his mate back on Earth like crazy,

but the females kept coming on to him,

and he had to keep rejecting them.

In the end, he just lost it and tore them apart.

Then why did you send him up there?

Well, it's because…

Our mission is

to get mammals to naturally mate, get pregnant,

and give birth, right?

Mouse 1 was very well-mannered, affectionate,

and great at mating back on Earth,

so we figured he'd get along with the females

and be great at mating in space too.

And you're telling me this now? Are you kidding?

I just found out.

You're laughing?

Oh, man. How did I miss this?

This is amazing. How is that possible?

Can you get me a mouse?

For what?

No, I don't trust your motives.

This restores my faith in humanity.

He's alive.

He lives.

I can't believe it worked.

The very first surgery on the space station

has successfully saved a mammal, a mouse.

This is truly remarkable

as up until now, no surgery had ever been performed

in the weightlessness of space.

Yes, this has never happened before.

This surgery has proven

that surgical procedures are now possible on the space station.

As MCC chief,

I'm so proud of the expedition team and the tourist who saved a life.

Didn't she want to put the mouse down until a minute ago?

Not too shabby for him.

Your car will be here soon.

Yeah, okay.

You…

Wow! I mean, you!

Come on, stop.

Fantastic job!

You guys were really awesome.

That was insane!

Hey, move.

Eve. No, I mean, Commander.

You can call me Eve now.

What?

I never would've thought

to open his chest if it hadn't been for you, Doctor.

I think they can mate now.

I think they can mate and get pregnant.

We'll succeed this time, right?

Absolutely.

I have a really good feeling.

To be honest, I thought you'd just get in our way, so you kind of bugged me.

But you…

You're a great doctor.

I'm so glad to have you here in space!

Great work!

Let's give him a hand!

His heart is actually beating!

GO-EUN

You saved his life.

SPECIAL THANKS TO CHO JUNG-SEOK

This is

hell.

I'm in hell.

I shouldn't be…

doing this right now.

WHEN THE STARS GOSSIP

Where did he go?

Two men in different rooms with a picture of the same girl.

Oh, my God!

- It's 500 billion won! - It's still valid for another month.

If Kang-su finds out, he'll get jealous and take them away in a second.

What were you doing?

I'm not going to let Kang Kang-su take anything else from me.

Kang Kang-su.

Are you even human?

I was the one who suggested that and using Gong Ryong as the delivery boy.

And it was me who offered to do the IVF.

You have to do it yourself, no matter what.

Right now, I'm about to steal back my eggs.

I'm going to get those eggs back, even if it kills me.
