I don't dislike that arc, but it way worse than previous...
Princess, who seemed may be not smart, but at least not stupid, suddenly, out of nowhere, trying to beat servant of another royalty (wars happened for even smaller reasons) and get easily exposed with kidnapping (well, all readers understand from the beggining, but still). And after, even more suddenly, at the same moment, her brother confessed (timing can't be more shitty). Too rushed chapter.
