(Episode 4)
Don't step on it. It's my homework.
By the way, where are you from?
Jupiter? Mars?
Woo Jin, come on here.
- Why? - Hurry.
Gosh.
Done. Yes!
Nice!
- You can never beat me. - Gosh.
What's the point of being the top student?
Let's make it the best 2 out of 3.
You'll lose again anyway.
Practice some more before you challenge me.
Gosh.
Too bad.
Hey!
Woo Jin, let's do it again.
See? I told you.
She is from another planet.

(Part 1: BETA Project)
(Do Not Enter)
(Kim Woo Jin)
- Yes? - Where are you right now?
Where are you?
I'm at Eunsung Psychiatric Hospital.
Why did you go there?
Stay right there.
I'll be there soon.
(2pm at Eunsung Psychiatric Hospital)
(Eunsung Psychiatric Hospital)
Who are you?
- Who was that? - Catch him.
Hurry!
Hey! Stop there!
Darn it.
- Was it a woman? - Yes.
I heard her voice.
Did you lose her? Where did you lose her?
- Where? - Jeong Yeon.
What's going on?
Why were you here, and who was that?
Tell me what's going on.
(2pm at Eunsung Psychiatric Hospital)
She called me over.
Let's go to the police.
Let's tell them everything we saw. We need to catch her.
Before that,
you need to explain this.
It came out from So Yoon's body after she died.
I couldn't get a grasp of what it was, so I just kept it with me.
Thanks to you, I found out that it was a robot.
Then why did you keep it from me? Why didn't you tell me?
Because of your brother.
Were you secretly doubting him all along?
Yes. I couldn't trust you either.
But...
I trust you now.
We saw the culprit with our own to eyes.
- What about my brother? - What about him?
- Do you trust him now? - About what?
That he's not the culprit? Or that an alien is behind this incident?
Do you believe him?
I don't believe his stories either.
But my brother isn't the culprit.
Okay. I'll think that way from now on.
Think carefully.
(Embezzlement and Fraud)
My gosh, this is so frustrating.
- My goodness. - That little...
She had an oval face, and it was very small.
Also her eyes... Her eyes were round.
Everyone has round eyes.
- What about her nose? - It was sharp.
Overall, she looked very nice.
Try to be a bit more specific.
You said you're a top student.
How will he make a composite sketch with that kind of explanation?
What do you expect me to do?
Here.
Yes, it's her. She looks exactly like this.
How did you understand his explanation?
That's what you call a detective's hunch.
There are times when...
I can easily draw the culprit's face just by...
paying attention to the reporter's facial movements.
Okay, okay.
It's not my hands that do the drawing. It's my sixth sense.
You said it happened at Eunsung Psychiatric Hospital, right?
Okay. I guess that's all you have for me.
I almost forgot. My brother left me a message before he went missing.
- What did he say? - He said the culprit is Bluebird.
"Bluebird"?
Yes. Please catch that woman.
That's the only way I'll find my brother.
- What was that? - You were suspicious of me too.
Did you go through my room...
because my email address is Bluebird?
It was a weird coincidence.
That doesn't even make sense.
Your brother already knows my name.
Why would he use a nickname to tell you that I'm the culprit?
He would've said, "Han Jeong Yeon is the culprit."
Do you think Bluebird was a nickname for that woman?
Why is it Bluebird?
Whatever the case, your brother's last message is the key.
We need to find out what it means.
Let's go to the hospital first.
The hospital? Why?
Did you get hurt earlier? Where?
- Not me. I'm talking about you. - Me?
Are you okay?
This is nothing. It'll get better if I apply some ointment on it.
Please be a bit more gentle.
Doctor, will this leave a scar on my leg?
- No, it won't. - I don't want a scar.
- I'll do my best. - Okay.
- My gosh. - Gosh, that hurts.
I'm sorry. It hurts.
(Emergency Room)
Hey, I'm sorry for calling back so late.
- No, it's okay. - Professor Han.
Just a second.
Woo Jin, what are you doing here?
I'm here because my friend got hurt.
Really? I also got a call that my daughter got injured.
- Really? Is she okay? - I don't think it's serious.
- I'll see you at school. - Yes, Professor Han.
Hello? Yes, okay.
Dad, he's the guy I told you about.
- He brought me here. - "Dad"?
What a surprise. Since when did you guys know each other?
Well, we're taking a class together.
Really?
Thank you for your help, Woo Jin.
No, it's nothing.
I'll be off then.
- Bye. - Okay, I'll call you.
Bye.
You weren't being careful again, were you? You're all grown up.
I just tripped.
But what's your relationship with Woo Jin? Do you like each other?
Is that why you've been missing your medical treatments recently?
It's nothing like that.
We're just... There's been a lot going on lately.
Look, you're being suspicious.
- You're getting the wrong idea. - Be honest with me.
Beom Gyun.
What are you talking about? No one's here.
He brings in a bug and starts talking about Bluebird.
That Woo Jin kid must be taking after you. He's so weird.
Wait. I just heard something.
What? What did you hear now?
Let's look a bit more.
Fine, let's go.
I'm here. I'm going in now.
(Haksa Residence)
Gosh, why did she get here so fast?
How's your leg?
By the way, why didn't you tell me that Professor Han is your dad?
I never asked you what your dad does for a living.
And you need to tell me if there's anything else you're hiding from me.
Stop confusing me.
Why are you so confused?
That's not what I meant.
I'm confused as to whether I can trust you or not.
Gosh, okay. Fine.
Why do you take everything so seriously?
Come on. Let's organize this.
Please speak to Professor Han.
Woo Jin is really not the right fit for the position.
You know that you're the only one who can change Professor Han's mind.
All right. I'll talk to him.
Gosh, the fine dust is very bad today.
- Hello. - Hi.
How's Jeong Yeon?
It wasn't anything serious. She's fine.
- But Woo Jin was with her. - Woo Jin?
- You mean Kim Woo Jin? - Yes, I think they're close.
They're in the same class too.
Professor. Speaking of which,
could you please rethink hiring him as the research team's assistant?
Why should I?
I don't think those in the team are happy with the idea.
The one who's at the top is everyone's enemy.
Isn't that the reason?
Frankly, I'm uncomfortable around him as well.
I think he's too self-centered...
I need him.
Aren't I the dean of the department?
Right. Okay.
- Oh, wait. Hold on. - What? Why?
- This. - What is it?
This is such a great photo of me.
I should keep this forever.
Send it to me.
Goodness.
Smile like that, please. Why are you so tense all the time?
You know the situation.
We'll be able to find him.
Just trust me.
Don't talk like you're older than me.
- What month were you born? - Me? April.
- Forget it. - What?
Hey, what month were you born?
- Show me your ID. - Gosh, just forget about it.
- Just show me your ID. - Drop it already.
What's the matter?
(Kim Beom Gyun)
Is it you, Beom Gyun? Beom Gyun, Beom Gyun!
Hello? Hello?
Geunrin Park at 2pm. Come alone.
What's wrong? What is it?
It was that woman.
Just hide and watch.
Go to the police right away if anything happens, okay?
You be careful. Don't overreact.
Gosh, who are you? No! Hey, don't!
Darn it.
Who are you?
Let go. Let go! Gosh!
Why is she here? I told you to come alone. Why did you bring her?
- Why can't you trust me? - Beom Gyun's phone.
How did you get it? Where is he right now?
Do you want to know?
Then tell her to leave.
I won't even say a word in front of that girl.
What are you trying to do now?
Leave us alone for a few minutes.
Hey, Woo Jin.
Just a few minutes. Wait for me over there.
Do not let her get away.
Now, tell me. Where is Beom Gyun?
- Why are you hanging out with her? - What?
That girl, Jeong Yeon, is an alien.
You know my brother. I asked you where he is.
Why are you asking me?
You should ask that alien.
- Are you feeling all right? - I'm not crazy!
Aren't you the one who's crazy?
The students at your school died because of that alien.
- Do you know where he is or not? - I'm telling you that alien knows.
You. I'm asking if you know. Just answer my question.
She's the one who should know the most.
She's not the kind of person you think she is.
Beom Gyun must've been very stressed out because of you.
- You've been totally brainwashed. - Stop talking nonsense.
Wake up. You don't have time for this.
Beom Gyun might turn out like others did.
We must find him before that happens.
- So wake up, please. - You need to wake up.
Aliens don't exist!
Here's one. She's an alien.
What about this?
Will you still say she's Han Jeong Yeon?
Do you get it now?
Why? Did she say she's not an alien and that she just looks like her?
Have you confronted her and asked her who she is?
Do you...
actually want to find Beom Gyun or not?
Why are you alone?
Did she get away again?
Woo Jin, what's the matter?
Did something happen?
See? I told you.
She is from another planet.
You...
Where did you get it?
- I've always had it. - Since when?
Did you buy it? Did you pick it up? Did someone else give it to you?
Why...
should I tell you that?
It's from me.
Here. Your name is Byul from now on.
Byul.
- What? - You're Byul.
That's you.
The boy next to you is me.
What is this?
It's you.
You are Byul.
I'm...
not sure.
I have no idea...
who I am.
I...
have no memory.
Hello.
Yong Woo, Jeong Yeon didn't come to the appointment again.
- Again? - It's a difficult process.
She won't be able to recover her memory this way.
All right. I'll talk to her.
- What? - I...
have no memory...
before age 18.
I just... I just want to be happy.
So please stop this.
Just investigate the case.
- Hey, Lee Ho Soo! - It has nothing to do with you.
Who are you? Who says you can do this?
(Part 2: The Great New World)
I don't know either.
I have no idea who I am.
If I'm really Kim Joon Hyeok,
or if I'm someone else...
I...
don't remember.
(10 years ago)
That's me?
Who...
- Who am I? - From this moment,
you're Kim Joon Hyeok.
Joon Hyeok doesn't need to know.
We can't keep it from him...
What are you talking about?
You said he was dead.
Is he alive?
Is he? What are you talking about?
What is it that I don't know?
Your past is in this.
It's the videos of your twin brother's memories.
It's up to you whether to watch it or not.
Once you watch it, you might not be able to overcome your past.
Do you still want to watch it?
Don't do this to me.
I've been through so much.
I need you.
So give up now.
Just stay with me.
Bad memories are...
part of your life too.
However painful, cruel, and horrible the memories are,
they're part of you.
So accept and take responsibility for them.
I did.
But you don't have to do that.
Your choice isn't necessarily right.
Attention, General City citizens.
The city's fine dust concentration exceeds safe levels at the moment.
Is he dozing off or not?
If he's dozing off, he'd be a jerk.
He told me to look for Bluebird all night.
Then again, if he's sleeping now, he'd be a total jerk.
He even has insomnia. He can't be sleeping.
- Hold on. - What?
But it's strange. He hasn't moved in hours.
Could he be...
- a jerk? - A jerk?
Follow me.
Keep quiet.
Gosh! Let it go!
Joon Hyeok, do you know how much this finger is worth?
Without this finger, you won't be able to find Bluebird.
So...
have you found Bluebird with your precious finger yet?
You haven't even found him yet.
I told you, didn't I?
Do you still not have Bluebird's location?
I don't know.
My gosh, that jerk's a magician.
A magician? What does that mean?
That means she's an elite hacker who doesn't even leave a single trace.
If Human B decided to team up with him, he must be one of a kind.
We need to find him
That's the only way you'll be at peace.
The same goes for Min Young and me.
We need your help, Dong Soo.
Okay.
What happened to that hacker from General City?
He hasn't shown up yet after we lost connection yesterday.
Director Lee, an employee from City Hall has come to see you.
- An employee from City Hall? - His name is Lee Ho Soo.
He has something to say to you.
Memory lock?
Yes. Memory lock.
You guys are locking people's memories.
Do you think that's even possible?
- Officially, it's not possible. - You know well.
I don't have time for such nonsense.
Let's end our conversation.
Bluebird.
Did you order Bluebird to lock people's memories?
What are you talking about?
I'm asking if you're locking people's memories.
Aren't you going to admit it?
Then shall I tell you everything I know?
Shall we call the reporters and see if it's really impossible?
Then you should've gone to the reporters. Why did you come to me?
Because I want something from you.
I want you to lock my memory again.
Please excuse me for a moment.
You should come with me. It's something you need to know.
- Mr. Park Jin Gyu. - What's going on?
What is this?
What did you do to me?
No. This can't be.
This can't be happening. Why am I... Why...
- I'm going to sedate him. - Wait.
You just remembered...
abducting Min Ji, didn't you?
What in the world did I do to Min Ji?
You were an accomplice, weren't you?
- Chief. Chief. - Hey!
I...
Park Jin Gyu was an accomplice in abducting Min Ji.
But isn't something strange?
I get that Smart City is responsible for locking people's memories.
But including Kim Min Ji and Park Jin Gyu,
why are people slowly regaining their memories?
Why is the memory lock not working all of a sudden?
I'm terrified to death...
that those horrible memories that I have forgotten about...
might come back.
- Maybe the system broke down. - Look at him being stupid again.
How can a supercomputer break down?
It could always happen.
Then that would be a big problem.
One thing we know is that something happened in Park Jin Gyu's brain.
Let's try connecting Park Jin Gyu's care chip again.
That's dangerous. The care chip is connected to his nerve.
Meddling with it once is already a big danger. We can't do it again.
That's the only way we can find out.
What if something goes wrong?
No, I can't do it.
Let's do it.
I want to know too.
I'm so confused.
Go back to the day that Kim Min Ji got abducted.
(May 5, 2017)
- Mister... - The video isn't blocked anymore.
- It was a black screen yesterday. - Exactly.
- Why isn't it blocked anymore? - No, please.
Mister. Mister.
Mister.
Please. Mister, no. I'm sorry.
Mister. Please. Don't do this.
(May 5, 2017)
- Hey, rewind it. - Okay.
It's here. Bluebird is here.
"Unlock"? Did he just unlock it?
What is this?
No, please.
Please help me.
Please let me go.
Please. Please, Mister.
Bluebird wasn't locking their memories.
He was giving it back to them.
But why?
- Emergency. - Hurry up and locate him.
- He's in our server. - Mine got unlocked.
- Go check the central server now! - Yes, sir.
Bluebird accessed the supercomputer again, sir.
- What about his location? - We still can't track him, sir.
What is the control team doing?
I'm sorry, Director Lee.
Until when will you let him fool us like this?
Wasn't Bluebird working with Human B?
There must be a misunderstanding.
Bluebird is the reason why you started regaining your memory.
He's the one behind all this chaos in Smart City.
We'll lock your memory again.
You have that right since you're a citizen of Smart City.
- But before that... - Do you want me to catch Bluebird?
We'll be doing that.
There's something else you must do for us.
What is Bluebird's goal?
Human B locks memories while Bluebird unlocks them.
- So they're not on the same team. - But why would he do that though?
Is he trying to show justice?
Or maybe he has something against Human B just like you do.
Chief, please take care of Park Jin Gyu.
- What about you? - I need to meet Bluebird.
- Do you even know where he is? - He's in Smart City.
That's where I lost him.
It means that Bluebird is Human B.
Human B is responsible for locking people's memories.
Stop being unreasonable.
You said Bluebird is a hacker.
Then this guy must be the culprit.
(Smart City Entry Point)
- Hey. - Where are you?
I'm at the entry point. Why do you ask?
I'm here too. Let's go in together.
Are you okay?
Calming Care must've helped.
I'll be right there.
There's something I need you to do.
We couldn't find any records on Detective Kim before he turned 30.
Please find out who he is.
If you do that for us, we'll lock your memories again...
right away.
Gosh, I'm almost there.
Detective Kim Joon Hyeok, why are you trying to find me?
Bluebird?
Why are you unlocking people's memories?
Do you want to know? Then get out of there.
Wait. Hello? Hello?
Bluebird?
Why are you unlocking people's memories?
Do you want to know? Then get out of there.
Wait. Hello? Hello?
- Hello? - Keep going.
(Handam University of Science and Technology)
It's the videos of your twin brother's memories.
Who are you?
What are you trying to do with me now?
Hello? Hello?
(Haksa Residence)
I'll never do anything that would worry you.
I should think about Grandma as well.
I'll never go back to prison.
I'll...
never leave you alone.
(Haksa Residence)
(Handam-dong, 120-485)
You...
- know me, don't you? - It sounds like...
- you know me as well. - Is it you?
Where are you right now? Tell me. I'll meet you there. I'll come now.
(Handeukgi Bakery)
It's the alien's hideout.
(Handeukgi Bakery)
(Sejong Motel)
(Sejong Motel and Sauna)
Like I said,
wherever you are, I can find you.
Suit yourself.
But if you leave me like this, I'll never see you again.
I'll never go back to prison.
I'll never leave you alone.
Did you kill him?
Did you kill...
Ji Hyuk?
No, I tried to help him.
- That alien... - Beom Gyun.
I'm not talking nonsense.
It was a reasonable suspicion, and I checked everything.
I'm sorry that I lied, but I was waiting until things became clear...
because I knew you wouldn't believe me.
So is this what you've been doing...
while you were hiding here for a month?
When did you ever say anything that was right?
Why do you keep living in another world?
Why?
Beom Gyun.
- You should get hospitalized again. - I'm not crazy!
That alien is here. We can catch her.
Woo Jin, we need to catch her. Let me go!
Beom Gyun. Beom Gyun!
The alien disappeared before my eyes.
Can't you just let it go now?
I'm sorry, Woo Jin.
I can't let it go until I see it with my own eyes.
I can't quit.
I'm sorry.
I'm so sorry.
I should've told you everything back then.
No. I should've quit everything.
I'm so sorry.
Sorry...
Please don't do this to me, Beom Gyun.
I... I had such a hard time.
I need you, Beom Gyun.
So please stop this...
and stay by my side.
Woo Jin.
It's me, your brother.
It's me,
Beom Gyun.
Kim Beom Gyun.
(Circle)
You really can't remember?
How can I look the same as I did 10 years ago?
Did you really make this with your mom?
Can you remember now?
I heard that Jeong Yeon can't remember her childhood.
Why are you curious about that?
We need to find Beom Gyun.
It's blood!
It hasn't solidified yet.
- Maybe Beom Gyun got attacked here. - Beom Gyun.
That wasn't there earlier.
- Hey! - My brother has disappeared.
Detective Kim's real name is Beom Gyun?
- Kim Beom Gyun. - Hurry up and check who he met!
Woo Jin... Where's Woo Jin?
He must know where Woo Jin is.
Human B is locking people's memories?
We can use Detective Kim as a bait to catch Bluebird.
Then what? What's next?
Are you even planning to make me commit murder?
We must find him.
