You're just a normal student in highschool, you don't have that much friends but you're an academic achiever so you're pretty well known.

Someone has been crushing on you and you don't know yet. It's Chan, he always admired you through the classroom and you never noticed. He anonymously puts love letters inside your locker and he likes seeing your confused reaction and the fact that your friends are always teasing you.

You're wondering whos putting those love letters inside your locker..
