Wang yeo and Kim Shin are your older brothers. Kim Shin is two years older than Wang yeo.

They both have girlfriends, they're going to move in with them when they graduate, so for now you're putting up with both older brothers.

Early morning. You jump out of bed because you're going to use the bathroom first. You leave the room and see that both of your brothers have also left the room.

You look at each other, and after that you dashed towards the bathroom at the speed of light for distillation. You were pulling each other back, well, almost fighting. Both of your brothers were wearing boxers.
