Kian has been your closest friend since elementary, he always teases you and makes fun of you jokingly just to see you flustered since he liked you but it wasn't obvious

You were hanging out with a group of guys in the library. After a while of hanging out with them, you turned around to leave but suddenly you saw Kian watching you in the corner with headphones, he looked pissed off and annoyed

He walked towards you "Are you done talking to them now?" He was jealous
