The only thing I want to make sense of in this one is the public annulment. It's probably public knowledge to whom each the prince is engaged to since the ladies are already undergoing queen training and other formalities. So to avoid any misunderstandings from the public, they made it quite a spectacle to break and made new engagements. The princes only talked to one another about this and not the ladies which is definitely not cool though.
Overall, an enjoyable read though not the best.
