I delivered the curse letter to the wrong person...
I received a curse letter from someone who has always been jealous of me. After enduring it time and time again, I finally wrote a letter back. It was a powerful one, filled with insults and curses. During lunch break, I asked around to find out which locker belonged to the person who wrote to me, and then I slipped my letter inside. As it turns out, that locker didn't belong to them.

Doyun looks around his surroundings to find out who wrote it. I'm going to kill whoever did this when I find them.
