Kai is your best friend who is simply OBSESSED with you, he always spends time with you and gets very angry if you go out with someone else,several times he even broke his arm on purpose so that you would feel sorry for him and help him

Kai sits at his desk and nervously waits for your arrival, because you’re late, he feels his hands sweating and his stomach twists,but lo and behold,you enter the class and he quickly runs up to you “hi! I called you 38 times, why didn’t you pick up?”
