You got here earlier than I...
(Episode 6)
No.
(Smart Edu-City Preferred Bidder Selection)
That took longer than I thought.
I ran into some interference.
And the notebook?
Please leave if you're not the director.
Jeong Hae Seong.
How dare you come in without knocking?
I told you to all leave.
Who do you think you're talking to?
Come with me.
Out, everyone.
You'll pay for this if it's not urgent.
What's going on?
My father who went missing 22 years ago.
Agent Jeong Jae Hyeon. This is his notebook.
I need you to answer...
all my questions.
Why was this notebook...
at Byeongmun High School?
I can kill you here and now.
So talk.
Why was my dad's notebook...
at Byeongmun High School?
Agent Jeong Jae Hyeon's last mission...
was the same as yours now.
Jeong Hae Seong. Open the door!
- Director! - Jeong Hae Seong!
He went in to find the hidden gold bars.
We have no way of knowing if he's dead or alive now.
You piece of crap!
Why did you keep it from me?
Why didn't you tell me?
The circumstances of an agent's mishap on a mission...
are never shared with anyone.
Don't you know that basic rule?
Whether Agent Jeong Jae Hyeon's your dad or not isn't important.
What's important is whether or not you complete the mission.
Over 20 years have passed since my dad vanished.
The suffering I've been through...
was for that stupid reason...
You should never have known.
I'm sorry you found out like this, Agent Jeong.
You call yourself human?
Jeong Hae Seong!
Are you out of your mind?
You tried to punch the director.
What's wrong with you?
We're checking the ID of the dead man, Kim Hyeon Ho.
We're looking into why he had that notebook...
and what he wanted to tell you.
Don't you know...
what you did could bring everything to an end?
Did you know about this, sir?
Uncle.
Tell me the honest truth.
Did you know my dad disappeared...
while on this mission?
I didn't.
He vanished when I was nine.
Then, he reappeared like this when I was 31.
I'm his son,
but I don't know what he was doing when he disappeared.
Is that even right?
This darn place knew and still...
I'm sorry, sir.
I can't do this anymore.
Hae Seong.
Hey.
I need to...
I need to take a short break.
(My dad's)
The empty space in the basement of the old building will be my HQ.
This place is safe.
(Byeongmun High has 4 scary stories)
(Ballerina, crimson eyes, the piano that plays alone)
On my dear son Si Hyun's birthday, we'll go to the observatory.
Did you think I forgot?
I'll wake you up when I'm back.
Let's go to the observatory, your favorite place.
(On my dear son Si Hyun's birthday,)
(we'll go to the observatory.)
- Is that blood? - No way.
- He must've fallen from the roof. - The roof?
- That's so scary. - Gosh.
- What happened? - I don't know.
What's going on?
Someone must've fallen. A lot of people have gathered.
- Who was it? - From the rooftop?
That's blood. This is horrible.
Ms. Oh.
Have you heard?
Mr. Kim jumped to his death.
Someone really died?
It was suicide?
Yes. They found a death note in his office.
Hey. Did you hear about the guard at the gate?
He fell from the rooftop.
I heard.
He was alone at school when it wasn't the time to patrol.
It's not the curse...
of the grandfather clock, is it?
"Don't be alone at school."
"When the clock chimes..."
"Crimson eyes will come for you."
- I hate you. - You scaredy-cats.
It's morning assembly time.
Where's my chair?
Ms. Oh. What happened to the guard?
Do you know anything?
I don't because I just heard myself.
Roll call time. Who isn't here yet?
Hae Seong's not here?
Shall I call him?
No, I'll do that.
Report how many hours of volunteer work you did by today.
Be sure to do it if you haven't yet.
(Order bouquet of condolence)
Seung Jae, put in the order for flowers.
That's all for today.
Isn't this the rookie's job?
Where's Hae Seong?
Where's Jeong Hae Seong?
Isn't it unacceptable to go AWOL?
The meeting's over. You can go.
- Let's go. - Whatever.
Yu Jeong.
I'd wanted to ask for a while.
How do you know Hae Seong?
What do you mean?
I sensed something between you two, especially when we had dinner.
You care and worry about each other...
and have each other's backs.
Was he like that? I didn't notice.
Be honest.
Yu Jeong.
- You fancy him, don't you? - What?
It's okay. You can tell me.
- Since when? - Don't be silly.
I have high standards.
That's odd. I have a pretty good hunch.
- I'll fancy him, then. - What?
Ye Na, that's...
I'm being very serious.
Why don't you change your mind?
You don't fancy him and there's nothing between you.
So what's wrong?
Okay, so, what I mean is,
why Jeong Hae Seong of all people?
There are many other nice guys.
I think Hae Seong's pretty nice.
I told you my plan.
- Don't get in the way. - What?
(Director Kim Hyung Bae)
Good job.
Director.
About Jeong Jae Hyeon's disappearance...
related to Byeongmun High...
Was Seok Ho aware of it too?
Jin Sang.
Do you know why people die in streams?
It's because...
it looks shallow but you never know how deep until you've stepped in.
- Right. - Seok Ho's like that.
I can't tell at all what he's thinking or what he knows.
I thought he was a simpleton.
We're not close enough for me to know his deepest thoughts.
- Did that answer your question? - Yes.
Go, then.
(National Intelligence Service)
A long time has passed.
Yes.
They don't glow in the dark anymore?
What?
Is something wrong?
Dad.
Did you feel lonely like me?
I looked back on the mission.
"Did Dad walk this path too?"
"Did Dad feel lonely like I do now?"
I found myself wondering.
I believed you were alive somewhere,
but I thought you could be dead too.
"He's alive."
"He'll be out there somewhere."
I believed so,
but it was so hard on me that...
I'm sorry.
I'm sorry, Dad.
It's okay.
Si Hyun.
Don't cry. It's okay.
Hey! I told you not to shorten the uniform.
Look at that side part.
I should split your head following that part line.
I styled it with the hair mousse at the sauna...
He looks like he should go to the police station,
not the teachers' office.
Hae Seong is out, so we have no choice.
I heard he already turned in his guns and ID.
Do you think he'll actually resign?
We should be prepared for that scenario.
Mi Jeong, prepare the necessary documents for Yeong Hun...
so we can send him to Byeongmun High this week.
Hae Seong!
Hey, Hae Seong.
Hi.
I wanted to just quit everything and go on a fishing trip.
But I should find this man.
NIS Agent Jeong Hae Seong, Domestic Team Four.
I will carry on with the mission.
Applause.
Take off the uniform, you punk.
Hey, Hae Seong.
Why did you miss school?
- Were you sick? - No.
- Did something bad happen? - No.
Then why did you miss the student council meeting?
Something came up.
You didn't even answer your phone.
I was busy.
I organized the notes for you.
Thanks.
You little...
How could you miss school without telling me?
- Where have you been? - We weren't worried about you.
We just needed more people to go to the Internet cafe with.
- Did something happen? - No, all's good.
Sit down, everyone.
Jeong Hae Seong, what happened?
I had to deal with a personal matter. I apologize.
This is school.
All students must attend school. It's the number one rule.
Just know that you'll get demerit points for your absence.
Is Ms. Oh upset with you or something?
Let's go to the snack bar before the first period begins.
I have to go somewhere.
Let's go during our break.
Where do you need to go?
Just somewhere.
(Byeongmun High Organizational Chart)
(Clock bell rings at 12am...)
The girl fell, hit the ground with her head, and died.
A corpse standing upside down.
(Upside down, at 12am)
And reverse...
time.
(Recording)
Crimson eyes.
(Recording)
The next one is...
the piano that plays alone.
We don't have a meeting today. Why are you here?
I was looking for something urgently.
What about you, Ms. Oh?
I came to check something too. Something urgent.
You must've heard about Mr. Kim.
Yes.
I heard he jumped to his death from the rooftop.
If you have nothing else to say, I'll be off.
Jeong Hae Seong.
You know he didn't take his own life.
You were on the rooftop when it happened.
You...
Who are you, really?
Jeong Hae Seong?
I could report you to the police right now.
You're not a student, right?
I'll tell you everything.
I am...
an undercover NIS agent.
(Fox)
What's up?
Sure, I'll meet you there.
Sir, so... I mean,
Mr. NIS agent, so you're saying...
Emperor Gojong's gold bars are hidden somewhere here,
and you came here to find them.
As for Mr. Kim, the man who was tussling with you...
What are you doing?
Listen to me carefully.
You have two options, Ms. Oh.
Option one.
You can actively cooperate with this NIS operation...
and do your duty as a Korean citizen.
- What are you saying? - Option two.
You can leak information about this covert NIS operation...
and face severe punishment...
for violating the National Security Act.
"Severe punishment?" What exactly do you mean?
- Am I going to jail? - For at least ten years.
Oh, no.
Ten years?
You have one day to think it over and decide.
I'll see you tomorrow.
Wait, hold on. Hey!
Why do I have to go to jail?
Did I commit a crime?
(Voice Memo)
So, this is your school's...
Sorry.
This is Byeongmun High's school anthem?
The song was written when Seo Byeong Mun...
became the first chairman of the school.
Seo Byeong Mun wrote the lyrics and composed the song too.
Lyrics by that man, and his song...
Sorry about that.
According to the notes, the keywords of the third story are...
"piano four hands," "silently moving keys,"
and "the dead girl's performance."
Will you have no problem accessing the piano?
I'll find out when I'm at school tomorrow.
We don't know when that guy might show up again,
so be very careful.
Who do you think that guy is?
He was after the notebook,
so he's probably looking for the gold bars too.
But we shouldn't jump to conclusions without evidence.
We should be careful, indeed.
Anything on Kim Hyeon Ho yet?
Oh, we combed through everything we could find.
He was just a civilian.
Unfortunately, I don't know how...
Jae Hyeon's notebook ended up in his hands.
It is a mystery.
The same goes for his motive behind wanting to meet up with you.
What did he want to say to you? We can't find a single clue.
In any case, there's one thing we know for sure.
Someone pulled strings to manipulate the investigation.
Otherwise, they wouldn't have...
wrapped it up in such a rush and concluded it as suicide.
Can you look into the detective in charge...
- Look into it. - Got it.
What about your absence?
All is good with Oh Su A, right?
Right, I was going to tell you about that.
There was a little hiccup,
but it's been taken care of.
(Out of Office)
(Our deepest condolences.)
(Rest in peace.)
What?
What matters is that it's been taken care of.
I made sure she'd never tell anyone,
so don't you worry...
So, you're saying...
an NIS agent bluffed an innocent civilian?
Hey, you threatened an innocent civilian.
You could go to jail for this!
Hey, you should've tried your best to placate her and win her over.
Why would you threaten her like that?
- Really? - Hey!
"Really?" It's common sense!
Hey, you. Get up.
Get up and go see Oh Su A.
Say you're so sorry about earlier. Beg on your knees!
Be nice and polite. Do whatever it takes...
to make her promise that she won't tell anyone.
Do you understand?
What the...
This is on me, so eat as much as you like.
If you want more food, just let me know.
Thank you.
My pleasure! Enjoy.
Well, then I'll leave you two to talk.
Okay.
It's not what you think.
What a mess.
- Let me pour you one. - No, thank you.
What did you want to talk to me about?
I'm sorry about earlier.
- That was rude of me. - My goodness.
Didn't you say this in your serious voice earlier?
"I'll give you one day." What's gotten into you all of a sudden?
I said that because I wasn't in my right mind earlier.
I'm sorry.
So? Go on.
- Hiding my identity... - Aren't you going to drink that?
I won't ask you to understand why I've had to hide my identity.
Regardless of the reason, I am not a student,
so I shouldn't stay at Byeongmun High.
But I implore you.
To uncover the truth behind Mr. Kim Hyeon Ho's death,
protect our country,
and punish those who have done wrong,
I must stay at Byeongmun High.
Also, my colleagues and I are discussing how we can...
compensate you for all of this, so...
I trust you'll keep it to yourself.
Listen.
Even if you say that, I feel...
Let's be honest.
It's not like you'll share the gold with me.
Even if I get something, it'll either be a watch...
or ring with the NIS logo on it.
Life is all about give and take,
but what's there for me to take? Nothing at all.
Even if I kindly keep your secret to myself,
I'll get nothing...
Ms. Oh, congratulations on being awarded the Presidential Citation.
You helped an NIS agent find Emperor Gojong's gold bars.
How do you feel now?
I simply did my duty.
As a Korean History teacher and a Korean citizen,
it is my duty...
to teach children accurate history.
Ms. Oh, I had faith in you!
I'm flattered.
And you're so modest too. You're the best, Ms. Oh.
Mr. Baek, go ahead and give Ms. Oh a permanent teaching position.
(Award Certificate)
Congratulations, Ms. Oh!
Congratulations!
Thank you!
- Oh Su A! - Oh Su A!
- Ms. Oh? - I will help you.
All of a sudden?
I give you my word...
that I won't tell anyone.
Mr. NIS Agent, I'll do my very best...
to help you...
so you can accomplish your mission without any difficulty.
You kind of sound like...
you're brimming with ambition right now.
No.
I just want to help you...
- because I'm a nice person. - What?
You haven't tried this, right?
This is really... My, look at all this meat.
Eat the meat with some potato.
Eat up.
The pork bone soup here is very good.
- But why, all of a sudden... - Eat up.
Yu Jeong is your little sister?
My gosh. Then that part-time employer...
must be your supervisor at NIS and Yu Jeong's dad.
Yes, precisely.
Jeong and An. Your surnames are different,
so she can't be your real sister.
I guess she's your stepsister, then.
No, it's not like that.
It's a long story.
Everyone has a story. I understand.
Ms. Oh.
If...
the person who killed Mr. Kim Hyeon Ho...
finds out that you were there at the time of the incident,
you could be put in danger too.
But you don't need to worry.
I'll be sure to protect you.
I promise I'll keep you out of harm's way.
Since you've made up your mind to help me,
I'll do my very best to wrap up...
What's wrong?
Your face is all red.
Maybe you have a fever.
My gosh. What do you think you're doing?
I mean...
Are the people at the NIS... Are they all like this?
- What did I even do? - Get a grip on yourself.
You're a teacher, and I'm a student.
I mean, we're both students.
- What? - I mean... What?
Whatever!
Don't say things like that with that face of yours.
How could he be so careless?
What's up with her?
That face of mine?
I appreciate the heads-up.
I wouldn't have known.
(Kim Hyeon Ho)
But Kim Hyeon Ho...
There was nothing I could do.
He was...
too haughty.
Goodness.
Hello.
You seem good-natured.
Who knew someone as amiable as you...
would do such a thing?
What was the reason?
Why did you send Jeong Hae Seong that letter?
(Personnel File)
(Domestic Team 3 until 2002, Domestic Team 4 until 2003)
I thought about it...
and figured he should know...
why Agent Jeong Jae Hyeon disappeared all those years ago.
Seo Myeong Ju, don't think...
you people are the only ones...
who know about the mission from 22 years ago.
Would Jeong Hae Seong even believe you?
I'll show him something...
that'll make him believe such as...
Agent Jeong's notebook.
That'll be a huge help to Hae Seong.
It has the answers to Seo Byeong Mun's riddle.
Relay this message to him at the NIS.
Tell him that he will fail this time...
just like he did last time retrieving the gold bars.
Mr. Kim.
Why are you addressing me like I'm under you?
I'll see you at school.
You won't allow any more murders?
Is this a treasure hunt hosted at a school picnic?
Or is this you...
being sentimental...
over a former colleague?
What if Jeong Hae Seong had met with a former NIS agent...
and had heard the truth about his father?
He would've come for you.
If I had been even a little bit late,
the entire plan would've gone awry.
Consider your gratitude noted.
(3. The piano that plays alone)
(The president of the piano club...)
The third ghost story...
is about the piano that plays by itself.
(Since then, the piano at Byeongmun High's music studio...)
The president of the piano club...
had a female student as his partner.
After finding out she was pregnant one day,
she told the piano club president.
His reaction was nothing but cold.
Left with no hope,
the girl chose to take her own life.
Since then, the piano at Byeongmun High's music studio...
What the heck?
What is that notebook?
What's with that scary story?
You were even more terrifying!
The key to Emperor Gojong's gold bars.
Ghost story number three. The piano that plays by itself.
Do you know where the grand piano is kept?
Beats me. I haven't been working here that long.
A grand piano...
from the 1950s?
While meeting with Dong Min's and Tae Soo's parents,
I saw it in the chairwoman's office.
However,
it'll be nearly impossible to sneak in there.
The annex isn't open at all times,
and it has its own security guards.
When do they open it?
When was it again?
There's the perfect day for it.
(The 24th Night for Byeongmunites, 2025)
You probably all know this, but the day has come.
The Night for Byeongmunites.
We invite those in politics, judicial circles, business,
as well as alumni to this event,
so I ask all members of the council to be present.
I'm afraid that won't be the case for Hae Seong.
What? Why?
Because it's not for just anyone,
especially someone with over 20 demerit points.
I don't understand.
How did I get over 20 demerit points?
For skipping school.
- How many are you at? - I'm at 19.
You can't spring this on me.
Why didn't you tell me in advance?
Didn't you read the student handbook?
It's all in there, so get reading.
Are you saying you did?
You said you would assist me.
How could you give me the maximum demerit points...
for skipping school?
Why are you biting my head off...
when you're the one who skipped school?
Besides, just because I agreed to assist you...
doesn't mean I'll only give you half of the demerit points.
I couldn't since there are rules.
Unbelievable.
Since when have you been a stickler for rules?
I can't believe you're talking to me like this.
How old are you?
Why would age matter at this point?
You're obviously older than me.
- Maybe if you... - Hey!
Move along.
Such sweethearts.
Anyway, this is bad.
We'll think of something and regroup tomorrow.
Look at him being thorough.
He actually bowed before leaving.
Unbelievable.
How can he think I'm older when he looks like my senior?
Unbelievable.
How do I get back at him for this?
(The Next Face of Byeongmun High)
I must ask, Hae Seong.
Did it never occur to you...
to give a reason before skipping school?
I needed time to collect my thoughts.
Who knew truancy would result in 20 demerit points?
This is bad.
This upcoming event seems like the only chance...
to get into the chairwoman's office.
There's a way.
Ms. Oh.
Allow me to officially introduce myself.
I'm Oh Su A,
a Korean history teacher at Byeongmun High.
Yu Jeong's father, I believe we met before.
Goodness me, Ms. Oh.
I apologize for my behavior that day.
(The Next Face of Byeongmun High)
(Benefits)
"The Next Face of Byeongmun High?"
The one selected will instantly receive 25 merit points.
That'll make up for the agent's 20 demerit points...
and give him five extra.
You have a point.
Why are you showing me this though?
Come on.
You can't be serious. It's absurd.
This isn't right.
How can I compete with kids at this age?
I even danced to promote myself the last time.
I'm quite shy.
I won't do it. No way.
I'm putting my foot down.
I won't do it.
Shall we?
Move it along.
Okay.
One, two, three.
Here we go.
Should it be taken this far?
It's my first time at one of these things.
Okay.
- You're here! - Gosh, hello.
Isn't that Ms. Kim?
I didn't know this,
but it turns out she's as good as any photographer.
She took all the photos of the former faces of Byeongmun.
I see.
Don't stand there nodding and head over to her.
Hurry and change!
Come on.
Relax and let's start simple.
- With a smile. - Sure.
A small one will do.
Smile.
Relax your mouth a bit.
Smile.
Relax your shoulders and let them drop.
- Are they stiff? - Good.
What's with his expression?
- He's usually more handsome. - He's so stiff.
He must be finding this too awkward.
- Maybe... - I know he can relax more.
You can do better.
- Just a second. - Sure.
What now?
He's a lost cause.
All I see is a log.
There aren't any usable shots.
He's hopeless.
Let's go.
Look.
Here he comes.
He used to model as a kid.
Check Hyeon Joon out.
Nice going, Hyeon Joon. Looking good.
No wonder he's vice president.
- That's what I'm talking about. - Nice!
That's great, Hyeon Joon.
A former model sure knows what he's doing.
He'll win at this rate.
What?
Check that out.
Isn't he sexy?
Guys, let's take ten!
Come here.
Agent, you're not here for a passport photo.
You need to smile prettier.
I was doing my best.
Look sexier.
- Water. - He'll have some water.
Didn't I at least do better than them?
You weren't any better!
One, two.
Okay, good.
All right. Watch and learn.
First, second, and third.
Byeongmun High School. Got it?
Come to Byeongmun High.
What are you doing?
Just watch and memorize.
Come to Byeongmun High.
That smile is a keeper.
Stay as you are. Hold on.
One. One, two three.
Nice!
That's it. "Come to our school."
See? Check this out.
Look. Don't you look way better?
What?
Look how natural this is.
Don't you look great? You're actually good at this.
Look. This is what you need...
to bring to the photo shoot.
You've got this, Agent Jeong.
- Got it. - Okay?
- Has the break loosened you up? - Sure.
We'll try again.
Smile gently.
That's it.
No way.
All right.
- No way. - Give me a shy smile.
That's it.
Look at him!
- No way. - He's actually good.
Could you take off your jacket?
My jacket?
Here we go.
- Good job, Hae Seong! - He looks great.
- Check that out. - No way.
All right. Give it to me.
Think you're a beast.
That's it.
Why don't you loosen your tie and unbutton your shirt?
Good! I love it.
You're swallowing the camera whole.
Okay!
Good job.
You did great.
Ye Na, you're up next.
Hae Seong, you looked great.
What happened during the break?
How did you get so good?
I received a private tutoring session.
He had a tutor?
I don't want to.
I won't roll up my sleeve, so just take it.
This is more than enough.
Everyone else looked relaxed,
but you might seem too rigid.
Let's take a few with your sleeves rolled up.
How many times must I refuse? I don't want to.
I don't want to, so don't give it a rest!
Ye Na, does it hurt a lot?
I'm sorry.
Ms. Kim, the truth is,
she got injured because of me earlier.
Can we go see the school nurse?
What? Yes, of course.
Come on.
We're good now. I'm fine, so get going.
Do you still do it?
Your wrist, I mean.
Ye Na, the gym teacher said to...
Hey, what's that?
I told you never to bring it up again.
Right, I'm sorry.
As a friend, I was worried...
My friend?
An Yu Jeong.
Have you no shame?
You're not my friend.
Don't think you're on my level just because I hung out with you.
Hypocrites like you who pretend to be saints make me sick.
Lee Ye Na.
Apologize to her.
- What if I don't? - Apologize.
You've got to be kidding me.
What are you two to each other?
- That's enough. Get back inside. - Why should I?
Doesn't it hurt your pride to hear that?
An Yu Jeong.
You're a piece of work.
But still, you had the audacity to lie to me.
Ye Na, you're mistaken.
We're not what you think.
You're despicable.
You make me sick.
Yu Jeong, we need to talk.
Was what I said a joke to you?
I told you not to interfere!
Not now but later.
Come see me once the photo shoot is over.
I saw what went on before making my presence known.
You have no idea about high school girls.
What don't I know?
You're Yu Jeong's family.
I can guarantee you...
that there's no high school girl...
who wants her brother to meddle with her friendships.
I get that but...
How could I not say anything and let her...
be treated like that?
Friendships...
are more complicated and delicate than we can imagine.
That's why you must give it time.
Besides, you know this.
You're only here momentarily while Yu Jeong is here to stay.
These are her peers she must go to school with.
At least for a year or maybe even more.
That's why...
you should let it play out...
until she comes to you.
In my opinion,
that's how you can help her.
It's not easy.
Did you think it would be?
Here. Hang in there and push forward.
Unbelievable. What do I do with a bonehead like you?
"Hye" is spelled...
with a Y in the middle.
How many times must I tell you that?
Spellings are hard to memorize.
Did you think it'd be easy?
Hang in there and push forward.
Again.
Write "a teacher's grace."
Why are you smirking?
I was reminded of someone.
Your first love?
Come on. Who was it?
Who?
There's this someone.
Wait. Come on.
Who was it? Tell me.
Why do you even want to know?
Don't be like that and tell me.
I can't sleep with this hanging over my head.
Wait, it's raining.
Oh Bong Ja, take this umbrella.
I told you not to call me by that name!
Just a second.
Mom, I don't go by Oh Bong Ja anymore.
- Why is there only one umbrella? - That's me being smart.
Don't leave him hanging and go!
What?
All right, fine.
What were you going on about?
(Have a Drink With Su A)
Sorry about that. We only had one umbrella.
Shall we? Where do you live?

I'll come find you soon.
I'll do it.
Ms. Oh, of course. She's the wild card of our team.
What do you think you're doing?
Stay right beside me.
Something's up with me. Get a grip on yourself.
That was unexpected.
The operation will be carried out at 8pm when the event begins.
When the chairwoman leaves her office...
is our best moment to strike.
- Cheers! - Cheers! You know...
how important this day is.
Would I be able to do this?
Calm down. I'm sure it's nothing.
Hae Seong, leave for now.
It's dangerous for you to stay.
I'll make sure nothing happens, so don't worry.
Also...
You look pretty today.
