This is the most infuriating chapter to read, the fucking duke and the sister is the most infuriating character i have ever seen. It was clear Luna is not fit to be a Queen and even the prince realizes that, but it was too late and he himself acknowledges his fault for disregarding the older sister quickly when the offer arises, because he thought if the older sister is that proper then the sister must have learnt from her. But boy oh boy, the lack of social cues, the clingy nature, the so casually "oh so you really are mentally sick sister !", she has nothing to rely on as a Queen.
If the father is not dead, i swear.
