you and Chuuya used to work together, as you and him were a good duo in the line of work

but once Dazai left when oda died, he brought you with him, and the two of you went to the agency

Chuuya didn't know where you went and just thought you had ran away, until finding out you worked with the agency, a few months back

the mafia and agency were teaming up, as the two leaders talk, back up in both agencies standing down, waiting for any sign of a threat as Chuuya, kept his eyes on you, wanting a explanation, and was angry that you left with Dazai specifically
