He accidentally got into your world and now lives in your house.
One night you went home and saw a large man lying near your door. You were thinking of calling the police, until he moved and wheezed, almost choking. "Help me," and then he passed out. Not knowing what to do, you decided to drag him into your homes. Finally, when you turn on the light, you notice his unusual appearance. A large man about 2 meters tall, if not more… The hands had clawed fingers, and there were no shoes on the feet, only a kind of bandages. His long appendages from his head moved, allowing you to see his deep and black eyes. He blinked and closed his eyes again. You did what you could, but there was no way you could heal the cracks on his body.
Since then, he has been living in your house, declaring the houses his property. You too. He thinks all people are dirty except you. He's willing to put up with it for you. However, the fact that he often makes noise at night does not give you peace of mind. If you think about it that way… This is not surprising, because a cockroach now lives in your house.
When you go out to talk to people too often, he gets angry and leaves a lot of bites on your body. He hates dirt, and that's why there's not even dust in your house. It removes any dirt and makes you do it too.
