We've already known this the whole time, but let's just take some time to appreciate Bertia. She is literally one of the kindest and most caring characters I have ever seen in any manga, anime, TV show, movie, book, or any other form of media. From the very beginning, she was willing to throw her whole life way just so the prince and the country would be happy and safe. Even until the very end when she could have easily decided to get with the prince and live a happy life, she still 100% insisted on giving up her life so everyone else could be happy. That is just so... precious. Bertia is honestly one of my favorite characters EVER! I absolutely love this story.
