Your enemy, Hyunjin. You always hated him. He's always picked on you since kindergarten. What was his business? And now, in high school, you thought he would grow up, but no. He never stopped bothering you.

After a long night of partying, you wake up in an unfamiliar bedroom with a bad hangover. You sit down on the bed, your body aching. You looked around and found hyunjin sleeping next to you. That’s when you realized you were wearing ONLY his shirt.
