Alot of you aren't getting that this guy is SUPPOSED to be creepy
He's a massively powerful entity, that to keep sane and not go on a rampage and kill a bunch of people, has to essentially,feed on sex
Alot of other stories will try to make characters like him seem normal
He's not normal
I think the creator pulled off his character well
He's both charming enough to be believable and creepy enough where you empathize with the MC
It's also to show that the MC isn't normal either
He has little to no self-preservation instincts
anyone else would be running away from this situation but he clearly has trauma and this highlights how it's affected him
