(actual people, organizations, locations, or incidents.)
(Filming was in compliance with COVID-19 guidelines...)
(and counseling was provided for child actors.)
(CGI was used in most scenes that include animals.)
There's a reason...
why I take this path rather than the shortcut.
One that is rarely occupied by others.
I enjoy these moments...
- of uninterrupted peace. - Please...
help.
Help...me.
But one day...
Please help.
I came across a dying boy.
Help me.
Annoyance swept over me.
How dare someone interrupts me when I'm playing a game.
News channels...
are covering his story.
And people cry as they watch it.
I wonder why.
(Mouse)
(Episode 12)
You were right, Mr. Lee.
You warned me...
I'd lose those I love if I don't embrace the change.
So, tell me. How does it feel?
Are you in agony?
No, it was exhilarating.
And now I feel refreshed.
It's as if my energy has been replenished.
My goodness.
Sir, what took you so long?
We just...
(Mom)
Look how desperate she is to protect her kitten.
A woman in her 70s was found dead hanging from a tree...
last night at around 10pm at Inoh Park.
She was found with severe bruises on her body.
The police are trying to find out who this woman is...
based on the handwriting of the suicide note...
they found at the scene.
(Woman in her 70s assumed to have committed suicide)
That's when I knew...
that the suicide note I read that night...
was actually written by his mother, not Kang Duk Soo.
I realized that the look in her eyes was actually resentment.
But that day, I was too blind to notice.
I started to wonder...
why she tried to kill her son.
I realized it was her last attempt to stop her son...
from committing any more crimes.
A person who has a high-purity psychopath gene like this one...
will definitely end up committing the same kind of crime.
Bong Yi.
Yu Na...
Please... Please don't hurt me.
Please... Please... Please don't hurt me.
Please.
Who... Who are you?
(Photo 20)
- What's that? - What?
The forensics team isn't here yet, so we just left it.
Sir.
Hoon Suk, wake up. Hurry.
Mom.
Who gave you permission to come here?
Do you know how much I looked for you?
Auntie, he did nothing wrong. I brought him here.
You forgot to take your cell phone,
so I left a note on the fridge, but I guess you didn't see it.
I'm sorry, Auntie.
- Let's go. - Auntie.
Hoon Suk. Hoon Suk, I'm sorry.
Wear your shoes.
Auntie, I'm sorry.
This is really driving me crazy.
I really don't remember anything.
I lied.
I didn't drink.
Please don't hurt me. I swear...
I swear I won't do it again.
You won't be able to anymore.
Ms. Kim sharpened this knife for 10 years...
waiting for you to get released.
But it'd be boring if this goes too easily.
So I tried pulling out a few of your teeth.
I'm not a low-life like that.
If it turns out I really did it, you can go ahead...
and chop off my penis.
"If anyone injures his neighbor,"
"whatever he has done must be done to him."
"Fracture for fracture."
"Eye for eye, tooth for tooth."
Why does this remind me of that case?
The culprit is a psychopath.
This guy is just like Sung Yo Han.
Eat up. I know you're hungry.
Once you return to being yourself,
you'll feel a rush of guilt.
It'll be very painful.
I'm sorry.
I'm so sorry.
Kang Duk Soo was murdered.
He was found at the scene of the crime 12 years ago...
with his penis cut off.
Darn it. How could he do this to her?
His target was a girl in her neighborhood.
She says she fought to keep him from taking her...
You said you'd protect Bong Yi. You should've stayed with her...
rather than chase Kang Duk Soo.
- Please let Han Seo Joon go... - Who are you to order me around?
It's not like I don't understand...
You understand? You know how I feel?
I'm sorry I missed your call.
I didn't hear it ring.
Did you go see Bong Yi?
Not yet.
I bet you'll be upset once you see her.
What's wrong?
I'm not sure.
I don't know why...
What are you thinking about?
What is it?
I'm sad.
The sunlight pouring through between the leaves saddens me.
I have to go.
She says she fought to keep him...
from taking her...
I'm sorry. I'm really sorry.
You scared me.
I'll stay here. You may go.
Okay.
Let go.
I said to let go.
All right. Gosh.
That punk. He's as strong as the Hulk.
Wait. Is he jealous of me?
That kid.
- Hi, Captain. - Where are you? Come in right now.
B, who had fought Kang Duk Soo...
to save A was seriously injured.
B was the child victim of his case from 12 years ago.
According to sources, despite her report to the police,
the police did not take appropriate action.
The police created a special investigation headquarter...
to conduct the investigation.
It gives me chills.
No wonder. The baby seemed unusual.
Once he starts crying, he won't stop.
Hi, Ms. Choi.
Hi. I'll watch him. You should go.
What? Okay.
I'm sorry. Don't cry.
I'm sorry, baby.
Thanks.
Good going.
One threw him keys to get him off the force,
and the other took those keys and broke in.
If you became the captain of the special investigation team,
you should've brought me in.
You only brought them in and Detective Lee. But you left me out.
I'm hurt.
Look. If Kang Duk Soo's mom didn't bring this to us,
you wouldn't have just been kicked off the force,
you would've gone to jail.
She wrote this and brought it over, then hanged herself.
It looked like she hurt her leg and had bruises all over.
I think Kang Duk Soo beat her.
How could he hit his own mom? That crazy jerk.
Nepo. You should've brought this to me right away.
Why did you take so long and make a mess of things?
I did not. I gave it to Detective Lee right away.
That jerk didn't give it to Captain right away.
I don't like that jerk either.
So put me on the special investigation team.
Given the content, she knew Kang Duk soo was after the girl...
and killed herself.
She probably thought he'd stop out of guilt...
if he knew his mom killed herself because of him.
She probably thought it was the best option.
But scumbags like that don't feel guilt.
That aside,
what were you doing? We couldn't reach you all night.
Think before you answer.
Otherwise, you're on top of the list of suspects for Kang's murder.
Well...
I was mugged.
- Wait... - What?
Mugged?
Bong Yi.
Are you awake?
- Lie back down. - Let go. How's Yu Na?
Don't worry. She wasn't hurt at all.
She's home with her mom.
Wait... What about Mr. Moo Chi?
I... I don't know.
Also, Kang Duk Soo...
died.
Did you know?
What? No.
How would I have known?
Come on. It's true.
When I came to, my wallet was gone.
Who mugs people like that?
Your car is a clunker, not some fancy import.
I know. It's not like they hit you from behind.
A truck was coming toward me in the pouring rain.
It crossed the yellow line. So I turned left instinctively...
and I saw the trees, so I turned right again...
I spun around two and a half times.
You don't believe me?
Check the surveillance videos. Let's go.
I have to get my wallet back. It has my only family picture.
- Fine. Go. - Let's go check.
Go. Don't do anything rash.
You're a suspect.
I wish I were the killer too.
I should've caught and killed Kang Duk Soo myself.
You have no idea how bitter I am that someone beat me to it.
You don't think it's him... Right?
It wasn't him.
He said he killed someone that he didn't even kill.
He wouldn't flip out that he didn't kill him if he did.
Moo Chi said the killer is a psychopath, right?
Yes. He said it was someone like Sung Yo Han.
If he's right, he'll try to kill that psychopath.
So we have to catch him first...
before he does. Got it?
- Yes, sir. - Yes, sir.
How dare you take Ko Moo Chi's wallet?
That annoying thief.
Who mugs people like that?
Your car is a clunker, not some fancy import.
It's not like they hit you from behind.
They're right.
It's strange.
OZ.
Hey. Why did you submit the statement late...
and make him call me a nepo?
- You should've brought it yourself. - What?
You only cared about being on TV.
What was that?
How could you forget that of all things?
Forget it.
It's a stolen plate?
Okay, fine.
How do I get it back then? It's my only family picture.
That's right.
Thank goodness I have this.
(Evidence Room)
(Restricted Area)
(Predator Serial Murder Case)
It's been a day since Kang Duk Soo's murder,
but the police have yet to find a suspect.
Meanwhile, the public has been hammering authorities...
to dissolve the special task force.
Even a petition has been posted...
demanding that the police abandon the investigation.
Hey, you're already here.
Is something up today?
The mood outside seems...
How are you feeling today?
Oh, I'm doing much better.
What are you working on?
I'm going to kill whoever killed Kang Duk Soo.
The people clearly don't want him to be caught.
That's because they see him as a hero...
and not for what he truly is.
"What he truly is"?
A psychopath.
A sicko like Sung Yo Han.
I'll know for sure once I verify a few facts.
Nepo, where's the evidence, darn it?
The incident happened ages ago.
That's what I call crossing the line, you punk.
The president being here doesn't mean you can slack off.
Just bring the evidence... Hello?
Did he just hang up on me?
Now I'm definitely not voting for your dad.
Follow me with an empty box.
Sure.
Any case evidence should be...
immediately sent to the evidence room.
I'm sorry, sir.
Is it the actual president?
That's what I said.
I've never seen him before in person.
He came running since it's a case the whole nation has its eyes on.
These are the photos of Kim Yu Na retrieved from Kang Duk Soo's phone.
They were taken the day after...
he moved back to his mother's house.
We assume that is when...
he began to plan his attack on Kim Yu Na.
- Do you have a suspect? - Yes.
What you're seeing are marks on the back of Kang's neck...
which were made with a taser gun.
When a taser gun grazes the skin,
it leaves small burnt marks.
A taser gun not making proper contact...
must indicate a female suspect.
That's right, sir.
On the taser gun found at the scene,
we found prints belonging to Kang's victim...
from 12 years ago.
And Detective Shin testified that he handed her the taser gun.
- This murder driven by revenge... - What did you just say?
"Murder driven by revenge"?
The burnt marks don't prove murder.
Yu Na said that...
Bong Yi fought with Kang.
That's when he got those marks.
Also, did you see the state she was in?
Could she have killed anyone?
- Moo Chi, that's enough. - Gosh.
Right. Here, here, and here.
As you can see, the marks on Kang's body...
match the injuries suffered by his young victim.
The killer must've...
- reenacted the case. - You're barking up the wrong tree.
The killer is your typical psychopath.
Stay put!
A psychopath?
On what grounds?
That's right, sir. Let me inform you why.
Here. What's your explanation behind this wound?
Isn't it obvious?
This wound is also...
- like the one on his victim... - You're right. But.
The others were inflicted on him before death,
but this happened postmortem.
An artery passes right below it.
As you can see, no blood gushed out.
He was already dead when the killer inflicted this wound.
Don't be so informal.
The killer missed this one at first.
Darn.
The killer doubled back after realizing his mistake.
He came back to slash Kang in the right place.
Captain, show us the photos of his thigh.
What you see here is a lighter burn.
A lighter burn is right here.
Stop being so informal.
For your theory to be true,
his past victim should have the same burnt mark.
But the girl doesn't have a scar that matches this.
Why not?
What...
What was the reason for it?
Exactly. What was his reason?
Okay, let's take a closer look.
There's a knife wound below the burn.
The killer made a mistake...
and cut Kang in the wrong place.
So he quickly burned Kang's skin to cover it up...
as though one would correct an error with an eraser.
Can that detail alone...
determine the killer as a psychopath though?
Psychopath Unabomber who targeted random victims...
with lethal bombs,
scratched out the errors he made...
on letters he sent to the police and the media...
until he made a hole in the paper.
He didn't just stop at correcting his mistakes.
It was as if he wanted to erase its whole existence.
Psychopaths like him are known to seek control.
The one who killed Kang Duk Soo...
is someone who is compelled...
to be in control of every situation.
He tried to burn...
the cut he made by mistake...
because it was a cut never found on Kang's former victim.
He didn't want to leave...
even the smallest stain on his replica.
And that's not all.
On top of the bruises you see,
Kang also suffered internal fractures.
The killer made sure to not make bruises.
All of Kang's bones are broken.
Avoid the areas where veins lie.
It's how one doesn't leave a trace.
Kang was also castrated antemortem.
All of these are sadistic actions which were inflicted on Kang...
to maximize his pain. And sadism...
is a typical trait of a psychopath.
Therefore, this isn't a revenge-driven murder,
but one carried out by a psychopath.
Then how did the killer reenact Kang's case...
down to every last detail?
- Only his former victim... - Only his former victim?
The whole nation is familiar with this case.
Those rats we know as reporters...
kept revealing the details just to generate more view counts.
They couldn't care less about the little girl!
But not all was revealed on the news.
Captain?
This burn mark. The cigarette burn.
Only the investigating team knew of this detail.
It was never revealed online.
The detail is only written down on a police case file.
Who was it then?
It could be someone on our side.
Moo Chi!
Where's this handwritten case file?
It's currently located in the evidence room...
at this police agency.
Please follow this lead and keep me updated.
- Yes, sir. - This is as long as I can stay.
Are you perhaps Mr. Shin's...
Yes, sir.
My wife called to tell me she's pregnant.
It's a child we've been wanting to have for 10 years.
Your father is an admirable man.
I'm sure his son is just as great.
Thank you, sir.
You're Officer Jung Ba Reum, the nation's son.
I'm Officer Jung Ba Reum of the Evidence Managing Team.
It's good to see you back on your feet.
Thank you. I owe it to you, sir.
The victim may have deserved to die,
but this act was still murder.
And an illegal retribution should never be justified.
I'm putting my faith in you.
Catch the killer as soon as possible and show the nation...
that justice is alive and well.
Doo Suk, we're here to check...
the CCTV footage of the evidence room.
What's going on?
Nothing's out of the ordinary.
Someone within the department?
You dare say that in front of the president?
Pull reports on Oh Bong Yi's phone and credit cards...
and check her whereabouts...
from last night up until Kang's time of death.
I'll get on that.
Only the detectives on her case...
and the doctor who treated her are aware of that wound.
Was it really Bong Yi then?
That can't be.
What if it is? What if Bong Yi killed him?
Are you going to do nothing about it?
Are you going to let her be arrested?
Of course, not. The poor thing's been through enough.
Then get going before the task force gets to her.
Don't just stand there and help.
I'll clean things up here.
Sure.
Alcohol withdrawal has my hands trembling.
I owe Bong Yi so much.
My guilt toward her is what finally got me to quit drinking.
Let me peel that for you.
Yu Na, I read everything you said to the police officer.
But I came to ask you something.
Is it okay if I ask you a few more questions?
- We'll have to record this. - Okay.
You said you saw a pair of shoes at the hideout.
Can you explain what happened?
Please don't hurt me.
I heard a sound right then.
I was in a hurry to escape, so I went inside.
Someone locked the door?
Why didn't you scream? It could've been Kang Duk Soo.
It wasn't him.
But you didn't even see his face. How can you be so sure?
If he was a bad person, he would've opened the door and dragged me out.
He wouldn't have locked it from outside.
Yu Na, you're smart. Good.
And then what happened?
I was just really scared.
So I just hid there.
I'm not sure how long, but after a while,
I heard the door unlock.
But I was too scared to go outside.
And that's where you saw the pair of shoes?
- I'll bring a plate. - No, I'll bring it.
Try to remember what happened.
Well, I...
Do you have something to say?
What? Me?
No, I have nothing to say.
Mom, I'm sleepy.
Okay. She's tired, so I think we should stop.
I should put her to bed.
Okay.
- Weird, right? - What?
Oh, yes.
It's weird that a psychopath protected her...
and was kind enough to leave her shoes in front of the door.
Does this mean Bong Yi killed him?
Hey.
What?
Darn it.
What's wrong? Detective Ko.
We noticed you bought a knife with your card,
so we went to the store and checked.
- According to the owner... - What are you doing?
What are you doing to a patient? I told you she didn't do it.
- Take him outside. - Ki Hyuk.
Bong Yi, I know it wasn't you. Tell him it wasn't you.
I know you didn't do it. Bong Yi.
Bong Yi.
You...
Why isn't Bong Yi denying the accusations?
Why is she keeping her mouth shut?
- Detective Ko. - I think it was Bong Yi.
What?
She might've left traces behind, so let's get rid of them.
It'll be over if she confesses. Let's hurry.
Why?
- What? - Why are you doing this for her?
She's not even your sister.
I would've done the same for you too.
Bong Yi's been through so much.
She even lost her grandmother.
She deserves to be happy now.
I support her decision even if she really did kill Kang Duk Soo.
If you don't want to get involved, you can stay out of it.
No, I'll help.
I'll meet the person who filed the report.
You meet Hong Ju.
Make sure she doesn't get suspicious.
It was around midnight. I was on my way home...
after I had a few drinks with my friend.
I called you tons of times, but you didn't answer.
And I couldn't call Detective Ko because he was locked up.
I went to Bong Yi's house, but she wasn't there.
So I went looking for her...
and ended up going down the bridge.
That's where I found her and took her to the hospital.
As I was about to cross the bridge,
I saw a car driving toward me.
I fell down the bridge while trying to avoid a crash.
Hey! Watch where you're going!
Something felt a bit eerie,
so I came back at dawn.
Did you happen to see anything else?
No.
I see.
I'm not sure how long, but after a while,
I heard the door unlock.
It's weird that a psychopath protected her...
and was kind enough to leave her shoes in front of the door.
Bong Yi, I know it wasn't you.
Tell him it wasn't you. I know you didn't do it.
Bong Yi.
Bong Yi...
He was dragged here.
Officer Jung, I figured it out.
I know how Kang Duk Soo was murdered.
Yu Na heard a sound, and when Kang Duk Soo turned around,
she threw dirt on him.
That sound was made by the culprit who killed Kang Duk Soo.
When Yu Na went inside this cabinet,
the culprit locked the door so Yu Na wouldn't be able to exit.
Now, look at this.
Take a look at this.
The culprit moved this.
Once everything was ready,
the culprit waited from up there for Kang Duk Soo to show up.
Where are you?
Come here.
I'm here.
Bong Yi cracked her ribs and wrist.
There's no way she pulled Kang Duk Soo up the bridge.
She's only 50kg, and Kang Duk Soo was 70kg.
The culprit is a strong and healthy male in his 20s or 30s.
Look up there. That proves he pulled Kang Duk Soo up there.
He tied him up and pulled him up there.
Do you still think it was Bong Yi?
How could you suspect that poor girl?
It's okay now. The detectives won't bother you anymore.
Thank you.
No need.
Why did they suspect an innocent girl?
Get some rest. Rest.
No.
Yu Na.
Mr. Moo Chi?
At 11am this morning, the president visited...
the Kang Duk Soo special investigation team in Moojin.
Due to the president's unexpected visit,
the special investigation team conducted a brief on the case.
The president ordered a thorough investigation...
and encouraged the detectives...
I'm sure I put it in here.
(A few days before the incident)
Someone hired me as a hitman.
A girl once asked me to kill a scumbag.
I'll take over now.
This is my payment now.
Where did I drop it?
I heard a sound.
Is Officer Jung out?
Where is everyone?
Why are you so giddy?
Bong Yi was cleared and that's good.
Anyway, don't you think Bong Yi and Da Seul look kind of alike?
Do they?
Maybe.
Although Da Seul is much prettier.
Where is Officer Jung anyway?
I came to give him an invitation.
I wonder if he knows we won't be accepting gifts.
I'm sure he does. It's the son of a presidential candidate's wedding.
What choice did I have?
I said let's wait a little,
and she said she won't get married with a big belly.
Moo Chi. Look at this.
Look at this.
Our lucky charm.
Lucky Charm will obviously be a fashionista.
"A fashionista"? What's that?
You're so outdated.
Do you know what you are?
A terrorist.
- "A terrorist"? - A fashion terrorist.
I hope our baby is a pretty girl like her.
But why are you watching Yu Na's statement?
Stay out of our case.
To be honest, I don't want to catch the killer.
I'm sure this kid of all people wouldn't want us to catch him.
That's strange. Why does it look like she's lying?
- What? - Look.
She keeps covering her mouth with her hand.
A lot of kids do that when they're lying.
And she keeps looking up toward the right.
That's what little kids do often...
when they're lying or thinking of a scheme.
- Really? - Yes.
I told you so many times that I was a child psychology major.
- When she touches her nose... - That's also a sign she's lying.
When you lie, catecholamine is released,
which makes the nose itch.
I think Yu Na saw something.
Saw what?
You saw something, didn't you?
Don't worry.
The police will protect you.
The police?
Yes.
I'm sure Yu Na saw something, but she won't talk.
Go to Bong Yi.
She's the only person who can make her talk.
Yu Na may be in danger, so I'll stay here.
- Really? - Yes.
He's sure she saw something.
But she won't say anything.
So Moo Chi told her to tell him since he's a cop,
but she pressed her lips closed.
Really?
- The poor kid. - Did she see Mr. Moo Chi?
I'm sure she saw me.
Yu Na... Yu Na can't say anything.
You're the only person who can persuade her to talk.
Okay. I'll talk to her.
She'll tell me everything for sure.
I'll bring her then.
Let's go to her ourselves.
The doctor said you can go home.
That's right. That would be better. We'll go to her.
I'll tell Moo Chi.
Wait here.
I'll process your discharge quickly.
Okay.
What did she see? She couldn't have seen my face.
What is it?
She'll tell Bong Yi everything.
I can't let her and Yu Na meet.
Hey. What is it? We sent in all the evidence.
The thing is...
The clothes Bong Yi wore when she came to the hospital...
differ from what she was wearing in Ms. Choi's dashcam video.
- The clothes? - I found out by chance...
while putting the evidence away.
Look. They're different.
Wait.
What's this?
That's the murder weapon.
Hi, Bong Yi. They were backed up with processing discharges.
I'm almost done.
Hello, are you Jo Mi Jung's mother?
I'm calling because...
we'd like to interview you for a Moojin Serial Killer special...
I'll take Eun Sung out for a walk.
Ma'am. Ma'am. I'll take him.
Okay.
Ms. Choi.
Where are they?
- What? - Bong Yi's clothes.
You changed her in the hospital parking garage,
No one noticed because they looked alike.
The clothes drenched in Kang Duk Soo's blood...
and this knife in her hand.
Where did you hide them?
Bong Yi?
Are you all right?
Please hand it over. I know you're aware...
that it's a serious crime to tamper with evidence.
You can be sentenced to up to five years in prison.
Do you want your baby to grow up without a mother?
Ms. Oh Bong Yi,
you have been summoned to the station.
How many times did I tell you that Bong Yi didn't do it?
Her clothes and the knife she bought...
were covered in Kang Duk Soo's blood.
Yu Na, I'll get some trash bags,
so pack up these books and carry down the newspaper.
- Got it. - Good.
Are you guys moving?
Yes. My mom's frustrated by all the reporters...
who come knocking on our door.
Let me lend you a hand.
Yu Na, I hear you saw something that day.
What did you see?
It was you, wasn't it?
I saw this as you were closing the door.
In the end,
Sung Yo Han will take over my brain completely.
What will happen then?
How will I be able to handle him?
I'm scared.
- I'm terrified. - What are you doing here?
You must be upset about what happened to Bong Yi.
I'm scared.
I'm terrified.
I'm scared. I'm scared.
What on earth? Where did they go?
Yes?
What?
It's the knife, right?
Why did you call me first though?
I was worried that it would have...
Bong Yi's prints or traces of her DNA on it.
What?
To be honest,
I don't think she should be punished even if she did kill Kang Duk Soo.
I've posted at least 1,000 comments online.
Here you go.
What on earth?
Detective, is it true that Bong Yi was released?
Ba Reum, Mister!
It was tough, wasn't it?
- Anyway, let's go grab a bite. - Sure.
Hurry, Ba Reum.
I'm sorry, but I had no choice.
I have a baby, you see.
If anything were to happen to me,
I have no family or friends...
that could take the baby in.
I understand.
What about the favor I asked for?
Here.
Ms. Choi.
Do you think I killed him?
I did at first which is why...
I hid your clothes and knife.
But then I learned it wasn't you.
How did you know...
that it wasn't me?
I just did.
I just knew.
Get some rest then.
Thank you...
for not helping him.
Help...
Help me.
He deserved to die.
Why aren't you getting out?
Aren't you curious as to why Bong Yi was released?
You haven't asked.
How did Bong Yi...
Detective Shin found the tools that were used to kill Kang Duk Soo.
Right here
Not Bong Yi's knife but the actual one that was used.
The culprit must've wrapped it in a raincoat and threw it away.
It poured like crazy that day.
He must've thought it'd travel far away due to the strong current.
But the Almighty must've decided to help...
seeing that it stopped right here. That's what we found.
The knives were wrapped in Kang Duk Soo's coat,
and we detected someone else's DNA from the bloodstain on his coat.
Bong Yi got released because it wasn't her DNA.
I think the culprit also got hurt while stabbing Kang Duk Soo.
But you see,
the results we received were hard to believe.
I'm confused.
I don't know how to interpret this situation.

Jung Ba Reum and Sung Yo Han are fighting ferociously...
inside your brain.
Right now, your good nature is suppressing the predator's instinct.
What about the Suseong serial murder case?
Officer Jung really likes you a lot.
It's time for you to be happy.
I need to be prepared before Sung Yo Han's instinct...
suddenly takes over.
The owner of the blue toothbrush.
Is he your next target?
What's going on?
Detective Ko is a predator?
