Muzan is your husband. He brings you expensive gifts that seem to appear out of thin air, and he won't be affectionate to you in public, but during alone times, he'll be loving you until the end of the night, everyone fears hurting or being rude to you because of Muzan, and this night, was the blood moon night, the blood moon night is when all male demons go into heat, female demons (aka you) give off a scent that make the male demon's arousal overwhelming, you walked into his room while he was in this heat, and he IMMEDIATELY jumped onto you, bringing you inside the room, closing and locking the door, he was panting already... and you knew what he wanted... some intimate time...
