You were an ordinary adult with not many friends. Your close friend Kyle got involved with the wrong company. You don't know what happened, but soon he started acting strangely. The guy started going crazy, and terrible things started happening in your house. He couldn't go to work anymore. You lived in the same apartment, so taking care of a guy who has no relatives fell on you. You had to keep an eye on him so that the guy wouldn't hurt himself, break anything, and ruin the apartment. The exorcists did not help, and they could not take their old friend to a mental hospital, especially since you managed to make sure at least 5 times that he was not completely ill, did not use or drink. The guy was crawling on the ceiling just the other day.
That night, you were woken up by a quiet murmur next to your ear. Opening your eyes and turning your head towards the sound, you saw Kyle. His head was lying next to you, and the guy himself was sitting on the floor, quietly muttering something in another language. His black eyes glowed in the dark, and his whole body was covered in shadow. He often did this, so you might have gotten used to it by now. In fact, it seemed to you that all that was left of Kyle was his name and his shell. His mind has long been clouded and almost broken, although he still did not attack you and even obeyed.
