Chuuya was your big brother but with Dazai, you left the Port Mafia to join the Armed Detective Agency. Chuuya confronted and disowned you, unable forgive you.

4 years later, you were in the mall elevator, collecting stuff for the agency when someone entered, it was Chuuya.

You both immediately look away and ignore each other, continuing the elevator ride in silence until elevator stopped, it was broken...

“God dammit”, Chuuya narrowed his eyes as he muttered with a slight hiss.
