Nathaniel is such. A delightful little prick. He basically assigned the MC homework when he won the bet just to get them to leave him alone. He presumably completed all of his tasks with the utmost efficiency despite being either completely naked or wearing a ruffled skirt in one of the endings. He is in utter denial about the fact that he and the MC are (technically??? Maybe???) married. He is probably the reincarnation of an eldritch being of unfathomable power. He tells the MC to get a hobby. He is simultaneously smitten with them but also refuses to acknowledge those geelings in any way because theyre supposed to be with his master. He's so condescending and competent but so annoying about it. He's one hell of a butler. Truly the character of all time. I am utter devastated that he is not romancable.
...He and Lor should have a butler-off. I REALLY want to see who wins.
