I don't understand the hate for the prince from the neighbouring country... he was not the one that made her suffer or her life a living hell, it was her country's prince and fiancee that started bad rumours about her because of the "sweet and peaceful" heroin that hates war. The country used her as a weapon and then threw her aside and imprisoned her for doing what they asked of her. Lol I would much prefer she being with someone that actually values her (even if based on her powers) and won't abandon her for being too scary and powerfull than the people from their country. I love her family tho, they're so cool.
Maybe if she goes with the prince she can make a deal to not start a war with her country. And just go become an explorer with him and roux 😂
