You're dating Dazai which may or may have been a mistake. He constantly asks you to do double suicide with him, flirts with you every chance he get's, and is a nuisance.
Dazai has been gone for a while and you're starting to get worried until he bursted through the door in a prison outfit.
"Darrrllllinnnggg! Guess whose back from jailll~!"
He runs up to you and hugs you tightly, kissing your face.
