WALKING ON THIN ICE

DRUG USE ISN’T JUST A MERE
DEVIATION BUT A SERIOUS CRIME

A SINGLE WRONG
CHOICE CAN DESTROY

AN INDIVIDUAL, A FAMILY,
AND SOCIETY AS A WHOLE

You actually pulled it off, huh?

Congrats.

What's with that face?

This is no different from a business.
I took it too lightly.

I was lucky this time.

If it weren't for those b*stards,
I would've failed.

Even if a store has a great product,
if people aren't aware,

it just becomes dead stock.

And so, they do
discounts and promotions,

and keep shifting the display
to catch people's attention.

You're saying we need to promote?

Women always talk about drama.

I want junkies to always talk about us.

A buzz, that's what we need.

It looks like a delivery app ad.

Magical Pill — Vaca
First purchase: 100 won

Limited sale for ten days.

Don't miss it.

Our word is spreading fast.

Did you get the link?

Go on, it's only 100 won.

- Is it real?
- Awesome.

Even billionaires love good deals.

Nobody hates free stuff, right?

And then what?

Here you are.

We expand our customer base.

Attention - a secret deal for
returning customers only.

Refer a friend on repurchase
and get double the amount you ordered.

A one-time offer.
Don't miss it.

We build our customer base,
and when the repurchase rate tops 30%,

that's when we raise the price.

By how much?




Marketing is all about
attracting customers to our shop.

What's the essence?
Don't be led by change.

- Instead, create the change.
- Instead, create the change.

Shall we read it together?

There's something I learned
while working at the bank.

Marketing isn't about
following change.

It's about creating it.

Welcome.

Thank you.

You look so young today.

Nice to see you again.

Damn, is it jammed again?

Wow!

What are you, woman?

Were you the salesperson
of the month or something?

Pretty much.



You get...



And I get 2.85 million won.
Nice round numbers.

Why did you quit?

Because I was a high school graduate.

Hi.

Is your mother home?

EPISODE 5

Oh, thank you.

You remember me, right?
I came to catch a thief.

Yes.

Did you catch him?

Yeah, but we couldn't find
the stolen goods.

Looks like someone
snatched them in between.

Do you know anyone...

called James?

Nice new car,

just like the lawyer
you introduced me to.

I delayed the urine test,

bleached and waxed like you said,
and my results came back negative.

How can you be so perfect?

My after-sales service is on point.

Yes, I've heard of him.

He worked at Medusa.
I did part-time cleaning there.

I'm sure you knew, right?

- So, no personal connection?
- Pretty much.

I was a cleaner,
and he was much higher up.

I thought so too.

But how can your number
be on James's call log?

Oh, there was this one time.

I found his phone
and returned it to him.

He had two phones.

I think most of the managers
were the same.

I picked one up while cleaning.

So you quitting on the day
James disappeared is...

- just a coincidence?
- Did he?

Yes.

- You're about 165 cm tall, right?
- How'd you know?

I have good eyes.

Tell me about
what you did on the 22nd.

Why?

There's a suspect we think
was working with James.

You kind of... look like her.

Even the scarf is similar
to that one.

Nice.
Simple and handy.

So, are you working alone?

I have a partner
who'll be quitting soon.

You're not sad, are you?

Damn, nice shot!

My partner's pretty capable.
Works hard and does well.

A potential decoy if needed.

Then convince otherwise.

Nice shot!

I went from the hospital to my job.
You can check if you want.

What about that scarf?

Bought it at the station for 10,000 won.
The store's still there.

- So this isn't you?
- No, it's not.

My apologies.
I thought you and James were close.

Even ran a background check on you.

And as you just mentioned,

I found out your husband's very ill.

Medical bills seemed hefty.

Definitely not enough
to be covered working part-time

at a supermarket.

I borrowed money from all over!

Why are you asking me this?
Did I do something wrong?

No, no.
Just routine questions.

Occupational habit.

- I need the restroom.
- Sure, go ahead.

Plum extract?
Did you make this yourself?

Yes.

Very frugal of you.

Why would someone
like you do that?

Do what?

Kim Minwoo,
the other manager at Medusa.

You called him to the restroom,

and like... took your clothes off.

Just a moment.

Ma'am.

Here's what I think.

No one starts out at rock bottom.

Life just puts you there.

Stealing out of greed
versus stealing for your family...

At first, they seem very different.

But in the end, it's the same.

Both are theft, all the same.

Making someone yours is easy.

Find their weakness and
stoke their desires.

Once a craving is filled,
people can never go back.

Speaking from experience?

Be honest, and I'll make sure
your family never knows.

Well, the truth is...

I used to raise a dog.

The poor thing couldn't fit in anywhere,
so I took care of it.

I fed it and gave it attention.
Soon, it was ready to die for me.

You know... loyalty.

Did it die for you?

Nice shot.

Pretty much.

We got high
and ran into a problem.

Nothing big, just a few candies.
Then one guy overdosed, right?

Cops came, and I thought
we were all screwed.

But only the dog took the fall.

Only he ended up in jail.
Nice and neat.

Hope he's doing all right.

Hey, get me some water.

He said there's an easier way
to make big money.

That they even take people
in their thirties and forties.

He was the guy
who called in the hookers.

But when it came down to it,
I just couldn't.

I kept thinking of my daughter.

I said no, and he suddenly
jumped onto me.

My family doesn't know it.

How would my husband
and my girl think of me?

I have to keep this a secret.
Forever.

I'm begging you.

Excuse me,
I need the restroom...

Wait, my partner's got constipation.
It's really bad.

Could I get another glass of water?

Wait, um...

Are you alright?

Is everything...

Sorry, I have diarrhea.

Not constipation?

Both.
Constipation and diarrhea.

You really found nothing?

Nope.

Nothing related to James?

No money, no drugs, nothing?

No, nothing at all.

You still suspect her?

Making gochujang stew?

Chop up some veggies
and throw them in.

Mom.

In my hometown,
gochujang stew is a special dish.

- Mom?
- Yeah.

Why are you dazed out?

Sorry.

You've been like this
ever since the police came.

I must've been shaken.
The police came into our house!

I hope they catch
the culprit soon, right?

Mom, can a person be both
really good and really bad?

Huh?

We get along well, she's funny,
and she's very caring.

But sometimes,
she's very mean and dark.

- Dark?
- Yeah.

It's hard to explain.

Anyway, she really confuses me.

Is she a good or bad person?

Should I like her?
Or should I hate her?

I was suspicious too.
But her record's clean,

she has a good reputation,
and is devoted to her sick husband.

The more I see it,
the more I feel we were wrong.

My uncle passed from
pancreatic cancer too.

I saw how much
my cousin's family suffered.

You're just wishing she was clean.

We can't get a warrant
without solid evidence.

James is in hiding too.

How about we focus on Phantom again?

They could be pretending
to have lost their drugs.

No, that's not it.

There it is.
Your all-seeing eye.

Did you know
people call you the shaman?

What's your sixth sense telling you?

If your kid were starving to death,

you'd do anything to feed them,
even steal.

So you think Kang Eunsoo is the same?

My experiences tell me

that desperate people are the scariest
and the most ruthless.

If you put it that way,
I can't disagree.

That's how crime starts.
Then it spreads.

Like zombies.
With no vaccine or cure.

Once bitten, you can't go back.
You just keep doing it.

On and on.

Those who get bitten
go on to bite others.

People are...

like this cube.

Most of the time,
we only see one side.

But everyone has other sides too.

Just because they have a dark side
doesn't mean they're not them, right?

What if you erase that darkness?

That means they're
not the same, right?

So, all sides are authentic?

That's how I see it.
People have different sides.

Mom, I had the cube solved!

Just solve it again.

What about you?

Do you have a dark side too?

Huh?

The man the police are after...

James is the bad guy,
and not you, right?

Once a craving is filled,
people can never go back.

I used to raise a dog.

The poor thing couldn't fit in anywhere,
so I took care of it.

I fed it and gave it attention.

I used to raise a dog.

The poor thing couldn't fit in...

I used to raise a dog.

The poor thing couldn't fit in anywhere,
so I took care of it.

Making someone yours is easy.

Find their weakness
and stoke their desires.

PERSONAL INFORMATION

STRUGGLING WITH HER
HUSBAND'S CANCER TREATMENT BILLS

A thief that can be forgiven, or not.

Which one are you?

James is the bad guy,
and not you, right?

NEW MESSAGE

DK

HELLO, I'M A NOOBIE.
HOW CAN I BUY?

Not much more to go.

Just until two hundred million.

Yes, then I'll quit.

Transfer the payment
to the account below,

and we'll ship it
to the address you want.

HIGH-RISK ANTICANCER DRUG
BAEK DOJIN

Don't be shocked by that.
I recommend you shave your head.

No matter how expensive,
it won't stop your hair loss.

Not so expensive with insurance, right?

You're new to this, huh?
Didn't you know?

Insurance doesn't cover it.

Hey...

For me?

I... got the job.

You passed? Really?
That's amazing!

Congratulations!

Cheers!

Oh, wow!

Thank you... so much.

It's not like I did anything.

Your parents must be so proud.

You know what?

They say the hardest thing
is living diligently.

You pulled it off, Donghyun.

Your little brother's lucky
to have someone like you.

I just wanted... to live, you know?

Are we still in contact
with that money-grubber?

Oh, right.

Get him to figure out
who they are and how many.

Why so serious?

What?
Loan interest rates?

No, it's nothing.

What about Kang Eunsoo?

I checked with her husband's
family and friends.

She really did borrow money.

And the scarf is a common one too.

Yeah?

What about her alibi?

Here's the SD card.

Her neighbor's dashcam showed
her entering the house.

But no footage of her leaving.

It's a redevelopment zone,
so there were no surveillance cameras.

Watching porn?

Look. Doesn't this look like her?

She's all covered up here.
It's hard to tell.

My gut says yes,
but there's no concrete proof.

Why are you even here, anyway?

I canceled my leave.

What's up?
I thought you had nothing special.

Trespassing cases.
Three times in the same neighborhood.

Witness statements and descriptions
all point to the same guy.

But it's strange.

Nothing was stolen
and nobody was hurt.

Weird.

Exactly. It's ill*gal trespassing,
so we have to investigate.

But there's no damage,
no clues, nothing.

It's frustrating.
I can't figure out the motive.

Maybe he's searching...

What?

What's going on?

Kang Eunsoo, you're under arrest
for drug trafficking.

You have the right to remain silent
and the right to an attorney.

Anything you say may be
used against you in court.

Let's go.

- Wait!
- Eunsoo!

How could you?
Are you insane?

- She sold drugs.
- How could a mom sell drugs?

Oh my god...

Sua...

You were the bad person.

Sua, let me explain.
It's not like that.

Sua! Sua! Sua!

Mrs. Kang.

Mrs. Kang!

Kang Eunsoo!

How unlike you,
dozing off in front of money.

Did something happen?

Our job is all about caution,
from start to finish.

Selling is different from using.

If you're caught,
it's straight to prison.

Don't hide anything,
or stab me in the back.

I won't let you slide twice.

I understand.

I guess I should tell him.

Actually...

You wear size 240, right?

I got these for you.

Go on, open it.

You lost your sneakers that day.

They looked worn out
to be used anyway.

I just wore it cuz it was comfy.

I have nowhere to wear this to.
You should've cashed me instead.

Gosh. You and your love for money...

Then don't wear them.
Just keep them.

It'll give you confidence
knowing you have them.

The rich and the poor's
perception of money is different.

The poor only think of chasing money.

But the rich think of how to use it.

I think too, okay?

My husband's hospital bills, the loans,
Sua's tuition, academy fees...

What about you?

Don't you want anything
for yourself?

It won't take long
until we hit your target.

You'll soon hand over
the leftover pills and be done.

Back to minimum wage,
two or three jobs,

nursing your husband, sending
your kid to school. Can you do that?

But I can't keep doing this forever.

- Why not?
- Because it's wrong.

Who in the world gets rich
just by doing good?

You're wasting your talent.

I think you can really shine
in this field.

Think about it.
What do you really want?

CONGRATULATIONS!
HERE'S A BIRTHDAY COUPON!

Heading to the hospital?
Get up, I'll take you.

CERTIFICATE OF APPOINTMENT

ACADEMIC AWARD

You really want to eat at this hour?
It'll all go to fat.

She's hungry after cram school.

You're not the only one.

- Lady, make me a decaf coffee.
- Sure.

CRIMINAL LAW LECTURE

EXCELLENCE AWARD
YOON JINHEE

The grand prize went to Sua, right?

Isn't she one of the top students?

Not the top.
She barely made the top 20.

That's pretty good
for someone doing art.

How come she's good
at everything?

She even started drawing
later than you.

If she had rich parents,
she'd have been unstoppable.

Didn't I tell you to go
to an art academy?

After-school lessons
can't beat academy education.

- Switch now, and...
- No!

Oh, what I meant is...

The art teacher is better
than the academy teachers.

Sua beat the academy students
and is entering the city contest.

What? Where?

The city art contest?

Yeah!
The art tutor recommended me.

And my HR teacher is into art.

I wish he were our
real school teacher.

He even graduated top of his art college.
I've never met anyone like that.

- Like what?
- You know...

He's just perfect.
Flawless. He's amazing.

Sua, are you sure
you won't go to an art academy?

I got a bonus payment.

If you want to go to arts high,
prep starts this winter break.

My answer's still a no.

Do you know how much
the tuition is?

It's ten million won a year.

You won't go?
Or you can't go?

I really wish you would act your age.

A girl who only thinks of herself,
and not money or parents.

C'mon, who gets to live
how they want?

- Definitely not you, Mom.
- Sua...

- What's that vibration?
- Huh?

Your phone's here,
but there's another vibration.

Weird. Isn't it yours?

My phone's not on vibrate mode.

Hello, ma'am.

I'm from High River City.

Come by and see
our new model home.

We're giving away
a microwave by raffle.

Thank you, but we're okay.

Mom, they have giveaways.
Let's go look.

The living room is a four-bay layout with
cross-ventilation and an extended balcony.

Wow, it's really nice!

- Can I sit here?
- Of course.

Thank you.

The master bedroom was designed
to look like a resort,

with en-suite bath, powder room,
and walk-in closet.

If you'll step out to the kitchen,

it's separated with sliding doors,

and fits a double-door fridge
and a kimchi fridge...

Mom, this place is amazing.

It's a solid 115.7㎡ unit.
Very well made.

The price is at 1.28 billion won.

That might be out of our range.

Mom, this is so comfortable.

Mom, I'm hungry.
When's dinner?

Soon.
Dad will be home soon.

Sua, I'm home!

Welcome back.

What's this? Bungeoppang?

You said you were craving them
a few days ago.

Wow, what's all this?

Welcome home.

You made all this yourself?

Yes, because it's a special day.

- Pour me as well.
- Sure.

Sua, I'm a lucky man, right?

Yes, yes.

You should find a man
like your mom, okay?

That didn't sound right.

Thank you very much.

- Cheers!
- Cheers!

- To our beautiful night!
- Cheers!

Mmm, delicious.

- Thank you for the meal.
- Enjoy.

Let's dig in!

It's really good!

- I heard you got a boyfriend.
- No.

Ma'am?

Uh, ma'am?

- I'm sorry.
- It's fine.

How much loan
can we take for this house?

The police called you?

Yeah. They didn't say why,
and just asked

if I'd lent Eunsoo money.

When I said yes,
they just hung up.

I was worried, so I asked Eunsoo
the other day when we met.

She said it was a misunderstanding
and wouldn't give details.

I hope it's nothing serious.

Sorry, it's a habit.

- Yeoju.
- Yes?

You said Eunsoo
borrowed money all over, right?

Any idea about how much in total?

Everyone, take your seats.

Not to alarm you, but something
unpleasant happened today.

Someone lost their money.
Does anyone know anything?

If you speak up now,
there'll be no disciplinary action.

Come see me privately
if you know something.

- Okay?
- Yes, miss.

End of homeroom.

Let's start with Hyeseon's piece.

Hyeseon relies on lines
more than planes.

That can flatten the form
and k*ll the depth.

Rather than tracing with lines,

use planes to portray it
more naturally.

Next, Jinhee.

I love that your white highlights
aren't overdone.

Well done.

But overall,
the sense of distance is weak.

Let's look at Sua's work.

Like Sua, think carefully about
the space between objects,

and vary how you render them.

See? The space breathes better, right?

Yes.

Good job, everyone.
Well done.

That's it for today.
Any questions?

When do you start prep
for the arts high entrance?

Will you be teaching it yourself?

Yes, over the winter break.
Only for those who sign up.

Hi. Our school is under the same
foundation as Seo-jung Arts High.

Does that give us an advantage?

That's hard for me to answer.

Yes, Jinhee's mother.

I heard canvases and supplies
have gone missing in the art club.

How are you handling it?
Have you found the culprit?

Ma'am, could we discuss
that privately later?

I heard there was a theft
in your class today, too.

If these are recent events, isn't it
likely that it was the same culprit?

There's a correlation.
Students in your class who take art.

Who?

Class 5, right?
Who's in 5?

Who could it be?

It's Class 5.

Class 5?

Wait a minute.
What are you implying?

I'm not shielding my daughter,

but Jinhee has no reason
to steal money.

Same for Yoojung,
who lives in our building.

Sadly, we're left with one student.

What?

There've been rumors among the girls.

I want you to be honest with me.

Sua?

I didn't steal anything.

I checked Sua's bag and locker myself.

There was nothing.

Not finding it
doesn't prove her innocence.

Let's call the school officer
and settle it properly.

Didn't you hear her?

She said she didn't do it.
There's no proof!

Why is a law professor
picking on a child?

Age won't undo a theft.

It's always the guilty
that demand 'proof'.

Circumstantial proof counts too.

We all know your situation.

Does it make sense for Sua
to carry something that expensive?

I bought them myself.
Want the receipts?

That makes even less sense.
Where'd you get the money?

It's a reasonable suspicion.

Stop whining and answer properly.

If it adds up, I'll apologize.

Now that you mention it,
that thing is pricey.

Are you saying the poor
aren't allowed to buy stuff?

I scrimp so I can give my child
something nice.

Do I need your permission for that?

Who do you think you are?

Fine, then...

What about this?

Two weeks ago.
Monday, November 1st, 11 pm.

What did you do with the art tutor?

I saw you getting out of his car.

Is that true?

What business does a parent have
with an after-school tutor at that hour?

Is that how Sua
got into the city contest?

A special favor
from a special friend?

Come on.
She has a husband.

- Actually...
- I'm his housekeeper.

What?

What did you say?

I'm the art tutor's housekeeper.

I've been doing it
before Sua joined this class.

When I realized that
he was Sua's tutor, I tried to quit.

But as you all know,
my husband was hospitalized.

Is that true?

Yes.

I knew her situation.
I couldn't just replace her.

And I couldn't tell the school.

Still, why would you give her
a ride at that hour?

She bumped her car
outside my house.

She called insurance
and gave them her car.

So I offered her a ride
on my way out.

I'm sorry if I caused trouble.

Also, isn't Sua's drawing too good
to be given special favors?

- True!
- That's a good point!

- Can't deny that.
- Right.

I think it was a big misunderstanding.
So let's wrap up...

We'll wrap up after the apology.

Apologize.
To both me and Sua.

You spread filthy rumors,
and you won't apologize for it?

From my point of view,
the circumstances justified suspicion.

You're the one responsible for creating
such suspicion in the first place.

And the thief hasn't been caught yet.

Unbelievable,
right to the bitter end.

We'll be going.
Come on, Jinhee.

Ma'am.

Please calm down.

You shouldn't leave like this
for Jinhee's sake.

Could we talk one-on-one?

- Ta-da!
- Wow, samgyetang!

- Did that lady give us this too?
- Yeah.

- And the side dishes?
- Yup.

Let's eat.

- Thanks.
- Yeah.

Wow, this is incredible!

That lady must really like you.

MONEY-GRUBBER: 32-GIL HAENGBOK-RO.
INSIDE THE BEDROOM'S BLANKET

What's wrong?

Huh?



THE SHAPE OF A PERSON
BY PARK SUA

GRAND PRIZE - PARK SUA

- Congratulations.
- Thank you.

Delicious!

No doubt you're mother and daughter.

You're celebrating
like it's actually alcohol.

But what if someone sees us?
Won't it start another rumor?

I asked Mom to come.

Oh, really?

Mr. Lee!

Thanks for helping last time
and for recommending me.

It's all thanks to you.

- Can I open it?
- Sure.

Mr. Lee?

Yeah.
You caught me off guard.

I love it. Really, I do.

You're handsome.

Hey! What are you saying?

I'm just saying he's handsome
because he is.

That trait is not mine at all.

- Yes, it is.
- No, it's your Dad's!

No way!

Cheers.

What's wrong?

I need the restroom.

- We should come here often.
- Yes, why not?

Eat, go on.

You're a gigolo now?

You sure looked like one.

I said I wasn't curious,
but the way you earn money is disgusting.

I feel tainted.

How much longer, huh?
Until when?

It's been ten years.
How do you think I've been?

I've been k*lling myself
to make up for what happened!

You think you can undo it?

The sh*t you did?

If you have any conscience,
do your part right.

Our family comes here often.

Mr. Lee, are you okay?

Where's Sua?

She went to meet a friend earlier.

What you said was right.

Just coming here
lifted my confidence.

Here, a gift for you.

You already have everything,
so I didn't know what to give.

But I saw your strap was worn out.

Don't you like it?

I'll get going then.

Want a drink?

Just one drink.

Welcome.

Oh, hello.

Please, sit here.

Being near the hospital,
many people come to shave their heads.

Things must be hard.

They say I'm getting better.
I might even go home soon.

That's wonderful.
You must be homesick.

Yes, very much.

Won't your family be shocked
to see you bald?

You should come again
after you recover.

Are you okay?

Of course.

Can you get off by yourself?

Mrs. Kang!

Seriously?
After a single can of beer?

Mrs. Kang!

Get up.

Get up.

Lean on me.

Wait.

Sua will be home soon.
Pull yourself together.

Thank you.

For not leaving you on the streets?

Not that.
That too, but...

I mean, at the open class.

Thanks for siding with me.

Forget about it.
That professor lady was annoying.

Such a smug.

She called multiple times to recheck.

That makes two of us.

Yang Miyeon is a b*tch.

I've always wanted to
say it out loud.

I see. You become honest
when you get drunk.

By the way, earlier today...

Who were the three people
seated by the window?

You don't have to answer.

My family.

The people who used to be
my family.

Today's actually my birthday.

Really?

Happy birthday.

Thanks. I haven't heard that
in ten years.

- Strange.
- What?

You're not usually this open.
But today, you seem different.

You should open up as well.

What do you really want?

That makes even less sense.
Where'd you get the money?

All of them.

I want to k*ll them all.

Anyone who harms
my daughter or my family.

And everyone who looks down on me.

I don't want anyone
to ever dare hurt me again.

Really?

Then...

How about we keep going?

WALKING ON THIN ICE

Boss, what should I do with the thief?

k*ll 'em.

Get treatment first.

We're in a life-or-death situation.
f*ck the wound, okay?

- And Kang Eunsoo?
- Eunsoo? There she is.

You know Hwang Donghyun too?

Then what about Phantom?

We've located Hwang Donghyun's phone!

Isn't this an opportunity for us?

We can pin this on Phantom more easily.

Just like you said.
