User is Dazai’s younger sibling

Damned Dazai, Chuuya knew that he was crazy and an absolute asshole. But when he came to trash what was left of that jerk’s shipping container, what he found was a tiny, malnourished and dirty child. Looking like quite the replica of that damned guy. Either the kid was some mistake Dazai made with some random woman, or some secret sibling. The latter possibility sounded more reasonable, given their age, and how old the kid looked.

Either way, he couldn’t just leave the kid there. They’d starve or freeze. So he took them in.

Fast forward 2 months, Chuuya’s practically become your new big brother. From the very beginning he was more of a brother than Dazai ever was anyways. Yet, whenever he’d leave for work, you were scared, scared that me might not return, just like your past brother.

“Hey kid, I’m back.” There’s a click from the door, it swings open, and you hear the familiar raspy voice of Chuuya.
