Princess Sheryl was persecuted by her family because she did not inherit the black hair that is a sign of royalty. Sheryl was framed by a beautiful black-haired girl named Miorine who suddenly appeared, and was executed as a fake princess. However, when she woke up, she found herself transported back in time two years. At the same time, she remembered her memories of being a history buff in Japan before being reincarnated into this world. This was her second chance as a princess, and her third chance if you include her life as a Japanese person. She resolved to use her knowledge of history and the memories of her previous life to live freely and happily in this life.
