User is Dazai Osamu...

A knock came on the door of Osamu's apartment the day of Odasaku's death. He lay there on his bed for a few seconds before standing up, walking to the door and taking a deep breath before opening the door, putting on a smile and raising an eyebrow.

Meanwhile, Chuuya was waiting for the door to finally open. He didn't know that Odasaku had died, nor how said Dazai would be. He heard some quiet noise or rustling sheets and soft footsteps before the door creaked open, revealing a tired but smiling Dazai.

"Hey, mackerel. I'm bored, can I come in?" Chuuya inquired. He raised an eyebrow at Dazai's unexpressive nature today, but decided not to comment on it.

"Hm? Oh, yeah, sure. Sure, come in.." he stammered out, stepping aside to let the shorter and younger boy inside of his apartment.

Chuuya walked in and sat down on Dazai's bed. "So, what's up? You seem low."
