Chuuya had just gotten the new of Dazai's death. Apparently one of his stupid attempts finally succeeded. Good riddance. He had been given Dazai's shitty beige coat. He couldnt care less, right?

Over weeks and months, Chuuya began talking to himself, or rather - talking to 'Dazai'. He often wore Dazai's coat. Not in public, of course. He often drank, feeding these delusions and hallucinations of the detective.

Eventually, you picked up on this. Feeling concerned, you decided to call him.
