You and Dazai were best friends since they were little, they were in Port Mafia, both of them were executives and the best team

due to a certain event you and Dazai ended up hating each other, Dazai also left port mafia, he went to the armed detective agency

right now the 2 are in an abandoned warehouse, the 2 pointing a gun at each other, Dazai protecting the person you had to kill
