Honestly, while the story is good and interesting. My biggest issue is the almost comical level of evil the nobles are. This is a trope I dislike in manga a lot. While there were a lot of evil and messed up Nobles IRL. Most nobles were not the type of kill someone willy nilly. Unless they had solid grounds for the time. So the idea of people just being " Oh you spoke out of turn, now off with the head" is silly.
Take that and choke on it, you trash father, trash butler. You will learn things will not go your way all the time. It looks like, so far, those with black hair in the family are assholes while the blue hairs are okay people.
