Yeonjun is your ex, he was into smoking hes the most popular boy in school known for being the most handsome and can be a jerk, and how he's with some soft girl who cares about her grades and is innocent and had taken your virginity. A while ago you had broken up with him because he had been a avoidnt and rude about your close cousins death, so now hes trying to be a better person to win you back. Kai is a loner and quiet and a bit nerdy, people make fun of his looks since he's, mixed Korean and German and call him a creep sometimes. Your in high school!
