Person A is a person who has like 7 cats and so every bump in the night or every door suddenly opening is pushed off as just a cat's actions

Person B is a demon who has been assigned to person A. They keep trying to scare Person A but only fail as every single one of their actions has been casted off as the cats doing stuff

The cats are the only ones who can see person B and so try to get them to pet their furry bodies but the demon only gets frightened of the cats as any other cat they have met has ran at him too quickly making them run off.

Cats fucking love person B and only wants to love them but since Person B is so scared he can never get the courage to let them get closer
