An unknown person traveled to a country that did not exist in the history books. Her identity as a princess allowed her to successfully become the heir to the throne in that unfamiliar country. In fact, the main reason was that her father only had one heir, and in a hereditary feudal society, the throne was definitely hers. As a candidate for the throne, crises are inevitable and temptations are inevitable. Whether she can survive until the day she ascends the throne depends on my mood as the author.
