Once Again (I Have Been There Once / Han Bun Danyeowasseubmida / 한 번 다녀왔습니다)

His bronchial tubes are quite constricted.

Oxygen saturation is low after suffering from respiratory distress,

so he'll need some oxygen.

How long has this been going on? My guess is several days.

I'm not sure.

When did it start happening?

His breathing was fine...

and he didn't have a fever when I stopped by the workshop.

Right, he was fine back then.

I think it started after his field trip three days ago.

I figured the fever was due to a cold.

Bacterial pneumonia can come along with a fever.

We'll check his blood and X-ray tomorrow...

and give him antibiotics as well as oxygen.

He had pneumonia, but all I gave him was cold medicine.

Moms aren't supposed to be medical experts.

Don't beat yourself up over it.

I'll get going then.

Sure. Thanks for everything.

Bo Young, have a seat. I don't want you to pass out.

Are you done in there?

How's your patient?

He's okay.

Were you with Dr. Yoon this evening though?

How so?

We went for some drinks.

So the patient's mother...

They used to go to the same church. She's his first love.

What about the boy's father?

I'm guessing she's a single mom.

What a dramatic reunion, right?

It is, but you're being very nonchalant about it.

You're saying it like he's some friend.

It'd be odd to talk about him like my ex-husband.

Anyway, we should get going.

Jae Seok.

Jae Seok!

Where on earth is he?

Where did he go without turning off the lights?

Maybe the convenience store?

Jae Seok!

What on earth?

What are you doing?

You're home.

Why are you cleaning at this hour?

You never clean up even when I ask you to.

Gyu Jin, I'm not cleaning right now.

I'm wiping my heart.

What are you talking about?

Well, I'm not in the mood to argue with you.

Leave and let me shower.

Go ahead.

Stop joking around and leave!

Take your shower. I won't watch.

Why do you never listen?

Gyu Jin,

I'm experiencing a crisis right now,

so please let me be.

What's going on?

Have you been cleaning all night?

What's going on?

Jae Seok, you're scaring me!

Gyu Jin, I've come to a conclusion.

What do you mean?

I've been leading too much of an honest life.

Instead of going out with friends,

I've been trying hard to adjust to my new workplace.

Work, home, work, home.

The lack of stimulants in my life has made me lose it.

Honest life? No. Insane? Yes.

Out of sight, out of mind.

I'll go back to my corrupt lifestyle.

I'll go back to being the old Yoon Jae Seok,

so don't try to stop me.

Hui Jae, it's me.

Let's meet up tonight. Where? Secret Club.

I expect everyone to be there.

Especially Chang Ryeol. He'd better not look old today.

Today, we're picking up women.

See? I'll now wash up.

What's gotten into him? Has he lost his mind?

Jae Seok!

Did you clean the utility room too?

Gosh, look how shiny the floor is.

Just like I suspected, it's bacterial pneumonia.

Thankfully, there's no secondary infection.

His fever is subsiding, so don't worry too much.

I want constant updates on his oxygen level and fever.

Got it.

Si Hoo, how's your breathing?

It's good.

You'll keep getting better.

By the way, it looks like you've grown a bit taller.

I'd say about 3cm.

And you lost some weight.

It's as if you've been trying to.

I haven't. Does it seem that way though?

Yes, you also have bags under your eyes.

My mom used to have them as well.

Si Hoo, please.

I see you're still as honest as ever.

He's not like his mother at all.

I have bags under my eyes?

Dr. Song.

What's wrong? Do you have more questions?

No, that's not it.

Things were too hectic yesterday...

that I wasn't able to thank you properly.

Thank you for treating my boy so late at night.

Please don't mention it. I was just doing my job.

Also,

please know that I was petrified last night.

Sense of relief washed over me when I saw a familiar face.

I wasn't in my right mind.

So what I'm trying to say is that...

You don't have to explain your actions like this.

I wanted to apologize for making you uncomfortable.

Please don't.

This is actually making me more uncomfortable.

Sure thing.

Then I won't from now on.

Sure. Good day, then.

That was kind of annoying.

Unbelievable.

Why does it feel like I've been sucker-punched?

Darn it.

She seemed so apologetic at first, but...

"Then I won't from now on."

That's one cunning cat.

Leave it to Gyu Jin to fall for someone like that.

It was mycoplasma.

What?

What Si Hoo has.

His fever is down and his breathing has stabilized.

I checked his nose for infections, but the results came back negative.

I'll run some more tests to rule out other suspicions I have.

Why are you telling me all this?

I thought you'd be worried.

I'm not.

Of course you do what's best for the patient.

I always trust your judgement as a doctor.

You must be chummy with Si Hoo's mom.

You even have gone to her workshop.

Right, I did go there once. Leathercraft is a lot of fun.

It clears your head.

How should I know...

when none of my friends work at leathercraft workshops?

You have the hospital director on your side instead.

Look at how sweet Jeong Rok is on you.

- Is that so? - Try to work it out with him.

He has a great personality, and he's cool and attentive.

He sure is a catch. Women adore men like him.

I should wish you good luck too.

Si Hoo's mom seems to depend on you a lot.

Also, she's your first love.

It's why I consider myself lucky.

Men go head over heels for someone like Bo Young.

- Exactly! - Exactly.

Exactly.

We just don't work together.

Exactly.

My gosh. Ok Ja, stop!

Are you kidding me?

What now?

What's wrong with you? You space out and then get angry.

Can't you see you're bringing down the mood?

Go home if you're going to be like this.

I wasn't in the mood anyway, so thanks.

I'll get going.

What? Stop right there.

Why are you being so moody today?

Are you experiencing menopause?

Seriously?

How can you say that to an unmarried woman?

Then what's the matter?

Honey, knock some sense into her.

Keep me out of it. I'm scared of her these days.

Unbelievable.

- Hello. - Hi, Mr. Song.

Are you off to your dance class?

- Yes. - That's right.

We have more free time during the day than in the evening.

Also, dancing in the evening...

makes me crave late-night snacks which doesn't help.

We stopped by to ask if anyone would like to join us.

I'm glad you guys are here. Can you take her with you?

Ok Ja, don't mope around and enjoy some dancing instead.

No, I'm not going today.

Why not? You were always against missing even one class.

But you love dance classes.

I don't anymore.

Besides, I'm not in the mood to dance today.

Ok Ja, don't be like that and join us.

I'll buy coffee on the way there.

Come on.

The more the merrier, right?

Also, she offered to buy coffee.

- Come on! - Let's go.

No wonder she's being criticized.

Anyway, this is supposed to be a secret,
