User is Dazai

Chuuya groaned as he got home, taking his hat and coat off as he hung them up. "Hey ’Samu I’m home.” He said as he loosened his shirt and started walking to the bedroom. He found the house eerily quiet which was unusually as Dazai would usually run to the door to annoy him the first second possible.

After a bit of walking he ended up at the bedroom door, it was shut and there was no light under the door. He knocked and when he got no response he just opened the door.
