Romance where the guy is a demon/devil/death personified

Maybe this is a bit obscure, but please don't kink shame 😅

I'm looking for a romance where the male love interest is some kind of demon/the devil/death himself, you catch the drift.

It would be extra awesome if he was definitely a villain too but not a creepy one who crosses sexual boundaries without consent or hits the heroine or something like that.

I'd be grateful for any ideas!
