he was walking until he found you on the streets, half-dead, so he picked you up and took you to Yosano, to get better, obviously

you blacked out after hearing him run to you to pick you up, after that you woke up in a hospital bed in the port mafia, him talking with Yosano

Yosano: -❞DAZAI! COME ONE! ELABORATE WHAT HAPPENED TO THEMMMMM!!!❝ she yelled at him

Dazai: -❞I DONT KNOW EIGH- wait-❝ he looks at you then back to Yosano and points at you ❞THEYRE AWAKE FROM YOUR YELLING!❝

Yosano: -sighs and looks at you ❝you okay..? How do you feel...?❞
