omega that is a comic book artists who works from home is surprised by a person who is sleeping outside of his house and has fake cat ears and a lingering attire ?(I think) then the omega tells him to come whenever he wants but doesn't come too often just like a cat (omega said so) and every time he came he had wired attires bc he is a prostitute and the omega bases his comic character like the cat like person who visits him, any ideas of the name of the manga ?
