Akumu kara Mezameta Gouman Reijou wa Yarinaoshi wo Mosakuchuu

The Duke's daughter Farara was abandoned by the Crown Prince and was imprisoned. The dream I had at that time was that my fiancé was robbed by a former friend as the president's daughter, Choko. "Who is Choko? Am I abandoned after my engagement?" Farara woke up from a nightmare the day after she was engaged to the Crown Prince and realized that she was 12 years old again! I'm not sure, but I don't want to live the same life as my dream. Reflecting on her arrogant self, she decides to start over with the aim of a bright and enjoyable future. Source: MU
