Jin looked at his ceiling. I remember the time I was happy with Jungkook. But all of that changed.

Flashback:

"Hello, Jin!!" Jungkook smiled, waving.

Jin waves back, Jungkook's smile growing bigger.

"I missed you."

Stop it. This is wrong. 

Then why does it feel so right?

Jin nods. He points at himself, then to Jungkook. "I miss you too."

Jungkook, understanding his message, grinned.

"Can you make some food?"

Jin nods. 

'Wait a little', He writes on a piece of paper.

Jungkook nodded. "OK."

...

"Thank you for taking care of my brother."

"No problem. It's just work, right?"

"Really?" A mischievous glint in Junghyun's eyes.

"Why isn't it?"

"Mm, whatever you say."

"What do you think it is?"

"Aren't you two a bit..fond?"

"Well, what's wrong with that? It's just a little."

"You text each other for hours. You're saying that's nothing?"

"It's just a little check-up."

"Should you come over to tuck him to bed and read him a bedtime story?"

"Well, he can't hear so-"

"That's not my point."

"Then what is it?"

Junghyun shakes his head. "Whatever you do, make sure Jungkook's happy."  

Jin knows what Junghyun is talking about. He knows. But he pretends to not know, because he's much too afraid of the truth. 

It's because Kim Seokjin is a complete fool.
