He's also can't annul his engagement without the King's permission since it's an arranged marriage meaning it is a legally binding agreement between the Duke's house and the Crown, also a Prince cannot exile ANYONE he is yet to have that kinda power and odd are after this he won't be the crown prince anymore if he has brothers.Fck that. You are the daughter of a DUKE!!! A DUKEEEE!!!!!. And that crown prince is just that a brat! The king and queen can just make another one.
How embarrassing for the royal family to have a crown prince with no manners and brains
