The true Princess Arya of Windermere Kingdom lives a peaceful life at the academy until a girl named Isabella steals her identity, claiming to be the princess of Windermere. Isabella not only takes over Arya's royal residence "White Heron Manor," but also publicly pursues Arya's boyfriend Sebastian, seducing him with a fake identity as a court painter. Arya calmly observes this farce while developing feelings for Reynard, who truly understands her. When Isabella forges official documents to organize an art excursion at the royal residence, Arya finally takes action, using legal means to expose the fraud and make all participants pay the price, ultimately finding the knight who truly belongs with her.
