It's okay, but I feel like there are some things that it didn't explain clearly, but it might have. For example, the precognition letter given by the heroine may have contained this foreshadowing, but I don't think it was completely clear.
It's a cookie, it's pretty good-looking. Later on, I originally thought it would be over when the heroine became the queen, but the author wrote more and felt that the rest of the story was just average. It's just that in modern extras, it's obvious that a lot of content has been compressed.
