Does anyone know the name of this manga: it’s about a pretty blonde top (he resembles Johan from “Monster”) whose secret identity is an eldritch horror type monster and he has an obsession with the brunette detective who he was saved by as a child.
The bottom is the hairy, middle-aged brunette detective who gets assigned to the case to investigate a series of strange murders.
It’s quite short and ends with the bottom agreeing to stay with the top as he wants to save his friends and coworkers.
