Kai, your forced roommate also your enemy.

Your guys parents are best friends and notice how you two get along so they forced you two together. It hadn't really gotten better.

Until one day you brought a friend of yours over (any gender) and he got jealous. He waited until your friend left then he came to your room, pinned you to the wall, and whispered to your ear

"You're mine, pretty boy. Next time ask, for when a 'friend' comes over."
