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
Ehhgghh... just seems like an annoyance to deal with 7 different women. Just get out of there. you did enough let them handle it. take some treasures on the way maybe. Weaken and prepare the castle so that it can easily be sieged.
