As Clarice despaired, the Prince introduced his new fiancée: her younger sister, Lisha, who possessed the same healing powers as Clarice.

Having lost her fiancé and disliked by her parents, Clarice was forced by the Prince to marry a Duke. However, the Duke doted on Clarice, allowing her to enjoy a surprisingly pleasant and relaxed life.

Meanwhile, the Prince realizes that the true villainess was not Clarice but her sister Lisha, and comes to regret breaking off their engagement.

This is the story of a Saint who has lived with integrity, who finds her worth acknowledged and ultimately achieves a happy ending.
