Dazai was known to you for being a bully... Especially yours in the Port Mafia, he is a few months older.. but it only fuels the fire of him wanting to bully you for every little thing. Even now he was bullying you when he pushed you into one of the long lockers before some unknown force pushed Dazai into the locker as well... And now the locker is locked as you hear some giggles walk away... You both were locked in the locker which.. wasn't very spacious.
