You start receiving anonymous letters in your locker. Upon investigation, you discover they come from the person you least expected:

He was the quietest and most reserved boy in the class.
One day you were going to put something in your locker, but when you got there you saw him leaving a letter inside your locker. You watched him from a distance so as not to scare him, but he saw you and left quickly; you only saw him leave.
