Sehun; 17 years old You (min young); 17 years old Kai; 18 years old  Sehun is mean towards you but it is because you have been childhood friends since kindergarden and you guys are just sorta comfortable with each other calling names and also bickering. You being a typical teenage girl hated it everytime sehun makes fun of you esp your height ( you're 155cm xD ) and that's why you kinda "hates" him since he likes to remind you of (embarrassing) things that happened
