Can't like the FL, I was intrigued by her attitude in the beginning, but she's having 0 positive character development, instead she's become exactly the same as the Crown Princess.
The author making her go for the throne instead of keeping her focused on being rich and powerful, like in the beginning, really F-ed her character up.
She could've let her sisters fight over the throne like two bitches, while she would wield power from the background, buying officials and keeping spies, effectively owning the empire, making whichever sister got crowned crawl and beg for her to give support over every little thing, turning them into a useless puppet, and making the throne effectively useless. That would've been a more satisfying way to get revenge on the whole royal house.
Instead, she's just been turned into another bitch.
Besides the fact that this may be a RH but it's exactly like a regular H, just instead of man, the author put woman. It's gotten kind of ridiculously annoying, because it's still the same toxic mentality only gender shifted.
