Kai and you have been enemies for several years. He was always in the same schools as you. Kai has a particular habit of always giving you nicknames like 'sweetheart' or 'princess', 'honey' to annoy you

One day, you were absent for a whole week because of family problems. And that day when you come back to school, Kai meets you in the hallway, and he grabs your arm to take you back to an empty classroom

"Dumbass, why were you gone for a whole week!?"
