어느날부터 경수는 갑자기 잠수를 타기 시작하더니 서인이의 단짝, 한채린과 사귀고 있다며 환승이별 통보를 하고선 유유히 사라졌다. 서인이는 며칠간 대학 강의를 듣지도 않고 집에만 박혀서 울었다. 친구들이 집에 찾아올 정도로 상태는 심각했다. 그러던 중, 대학 모임이 있었다. 서인이는 나가지 않으려고 했지만 친구들이 조르는바람에 갈 수 밖에 없었고, 그곳에서 축늘어진 모습의 경수를 마주한다.

pajama party

Us of tomorrow

Seo In-ah! Can we sleep over at your house today??

But... it'll be narrow... will it be okay..?

It's been a while since we had a pajama party.

Wowㅋㅋㅋ How many years has it been since we had a pajama party as a group??ㅋㅋㅋ

Um....I last did it when I was 18....so it's already been 4 years!

Come to think of it, it's really been 4 years!

Hey guys, who wants to go for a walk with me?

(Sneaking his arms together, he stands up) Let's go.

Yeah, uh..ok, okay! Anyone want to join the other side??

I feel a little better now that I'm outside~!

When you're depressed, you have to go outside?? lol

That's right! From now on, when you feel depressed, go for a walk outside!!

(At that time, Kyungsoo and Han Chae-rin are seen walking in the park arm in arm)

(Seo In-i immediately turns her head away).........(Seo In-i's eyes turn red again)

Seo In-ah, stand up for yourself. Those motherfuckers are trash. There's absolutely no need to cower before trash!

(Then Han Chae-rin approaches and laughs at Seo In-i)

Hey. And your friend pulled my hair and it hurt so bad I could die. Get on your knees and apologize.

Hey you bitch!!!!!! You want to get your hair grabbed one more time?!!! What the hell did you do that makes you kneel to Seoin you punk!!!! Instead, you're the one who has to kneel, you punk!!!!!

I never want to see trash like you again.

How could you do that when you were Seoin's friend? Get out of here right now.

You don't like it? I'm going to watch him get on his knees.

.........(Just watching quietly from the side)

Hey, Do Kyungsoo. Why are you just sitting there? Stop your hot-headed girlfriend.

Yeah. Rather, it's you, Do Kyungsoo, who should be kneeling. It's not Seo In.

Guys, I'll just kneel. (Looking at Han Chae-rin) Just kneel.

Haha. Okay. You should kneel then~ Ah! And after you kneel, say "I will never hit on Chaerin's boyfriend again. I'm sorry." Haha.

............I'll just do it. Then, it'll be over. (Forced to kneel)

"D, again...ch, Chaerin's n, boyfriend........"

(Then Do Kyungsoo grabs Han Chae Rin's arm and turns her around)

(Nervously) Just a little bit!!!!!!!!!!!!!! (Forcibly drags Chaerin away)

(Seo In-i sheds tears on the spot) Sob... sob... sob......

(We returned home and chatted and chatted until it was already 12 o'clock)

Haaaaaaam.....Guys...good night......Zzz.........
