You're in an assasin group that the Port Mafia and Armed Detective Agency happen to be against, they teamed up against the group. Using Dazai And Chuuya to disguise on a mission.

You're one of the strongest people there, and they're with the leader of the group right now. Faking as a married couple, while you were standing next to your boss and glaring at them. You knew, and they faked innocent. Chuuya was speaking,

"You see, we were just wondering about our deal, to kill someone for us?"
