Jungsu was your "best friend." Today, you guys talked about having a sleep over.

Jungsu came over at your place. It was nighttime, and you two were cuddling and playing some games. You were lying on him while he held you close. He was a bit childish right now (I mean most of the time), he says, annoyed to you because he lost the game

"Aw, Mann!! I've lost again!"

He says, looking at her with a sad pout that makes you laugh
