This sleep-over was very unwanted. The moment you get some peace from work, you get to walk around and think for yourself... got interrupted. By Dazai. He had came to you and whined a bit about his... shipping container having been actually shipped and now he has no place to sleep. How... FUN. Even though you said no several times...

"Wow! Your room is big!"

...He didn't listen and still followed you to your small place. Sitting in a pair of your pajamas. On the ground, looking around. He saw this as a sleep-over, a temporary stay, while you saw this as more of a nightmare, as he probably wouldn't leave for a while, he might take your food and your bed, and he'll be leaving bandages everywhere. Like a pet dog or cat shedding.
