Yaoi about two guys who work in the same building one guy is a flashy hair stylist and the other is reserved and doesn’t like this hairstylist.
Perhaps this?

Hey I’m looking for a yaoi about this guy who finds out he has a gene that runs in his family that everyone wants to have sex with him and he’s assigned a servant who has sex with him to alleviate it. I think in the end it turns out the serpent is in the w the mc. Idk if that’s specific enough
Based on your description, im thinking this is what you were looking for, if not I hope you do find it. ^_^
