Problem I have with this one is while one of the female leads is ok (just super Tsundere), the other is basically running around with the intellect of a 2 year old. She shouldn't be a romance target when she's apparently been sheltered from every single form of media, books, human anatomy lessons and whatnot since she was born, and also has the worst observational skills ever if she can't figure out getting dressed after having a maid dress her for over a decade. The premise of a Rich Girl who doesn't know common sense can be believed (many have no idea how to tip IRL for example), but taking it to this extreme just is a big turnoff.
