you and sumin have been friends since they started high school, they are currently in their last year.

their relationship has always been weird, I mean, they've always been friends but sometimes they both flirt with each other and when someone sees them they just say they're joking and that they are just friends.

now they are in history class, watching a documentary, but you notice that someone is looking at you a lot. you turn around and see sumin looking at you with a smile.
