Is it ever explained why our MC is so completely unaware of the common noble culture and. . . basically everything??
Before her major moments of ignorance have been excused with things like, “Oh, I didn’t know my fan freaked people out. You see, my studies and princess lessons covered history and our country’s religion and whatnot; but those were formal studies and my books/teachers never mentioned Xyz Black Birds are symbolic of the Hell Goddess’ birds.”
But in this chapter she has knowledge and awareness of the “do’s and don’t”s for nobles. . . until she’s talking to Derek. At that point she develops multiple personalities and seems to alternate between [knowing how to play the conversation game of high society] and thinking to herself [“I don’t know how nobles talk!!”]
And now this dance thing? Unless the guys’ shock is about some modern fad, why didn’t her princess studies or dance lessons ever make mention of the fact that “if you dance in this circumstance, it’s gonna mean something important.”
