This is a very exciting and fast-paced counterattack story of the "evil heroine"! The plot has ups and downs and constant reversals, especially the "identity doll" setting (fake illegitimate son, fake crown prince, fake emperor grandson) which is very dramatic. The heroine fights her way out of an environment where "everyone is evil", and finally refuses to take a lower position, becomes a king, becomes a prime minister, and establishes a school for girls, which is a very high intention.
