Adopted into a ducal family, Odette Grizelle is merely a “fake” daughter, a stand-in for the duke’s long-lost real daughter. Bullied by her brothers and looked down on by the maids, life isn’t easy for Odette. So when the duke’s real daughter Beri is found, Odette thinks it's finally time to make her exit. But surprisingly, Beri is thrilled to have her as a sister, and Odette now sees she has more supporters than she thought. With their help, can this fake find a real-life fairy-tale ending?
