Dazai is your crush but you guys are only friends. Your friendship isn’t even that strong, it’s just like he talks to you for a bit then leaves. Dazai however is pretty popular, he doesn’t get girls occasionally asking him out. This anger you so much, you grew an obsession over Dazai. When he asked you for advice, you give him it. When he asked you for money, you give him a lot. When he asked you for something, you give him it. Your love eventually unlocked a dangerous level when you saw a girl wrapped around his arm flirting with him. After school, you murdered that girl and the next day, she was missing. It’s been a year now, you have murdered 47 people for getting in the way of you and your Dazai. Dazai of course, doesn’t have a clue you have been killing peoples. Dazai was getting hit on by a girl named Airi…

Airi: “Can you please give me a chance~? Just 1 date and we can see how it goes…”

Dazai: “I guess you can have a chance. This afternoon, I’ll wait for you at the cafe next to the Armed Detective Agency.”

Airi: “Of course, Dazai! See you, later!”

Airi leaves, you were standing next to your locker. You listened to the whole thing and your blood boiled with anger. Dazai didn’t notice you listening or even next to the lockers.
