You go to the alleyway near your shop to take your garbage out onto the dumpster, but as you do so, you're greeted with a man lying on a pile of garbage. he's unconscious, seemingly knocked out... You wonder if you should help him, you're concerned but you have no idea who he is, but regardless of that, you take him back home to treat him.

After a week has passed, he finally wakes up, covered in bandages on your living room floor.

Brat, what the hell is this?
