Kai

You had an enemy that you hadn't gotten into since first grade (you're in 11 now)
It all started with some little thing, and then he started to put you down and literally mock you.

You also had a boyfriend whom you started dating in 8th grade and a friend who became as close to you as a sister.

But one fine day, you were walking to class at school. Suddenly, you noticed your boyfriend kissing your friend under the stairs. Tears immediately welled up in your eyes, but your enemy, who was also passing by at the time, suddenly embraced you, turning you around to face him, clearly trying to calm you down. In fact, Kai had long since stopped wanting to hurt you with his bullying, but he knew nothing but cruelty.
