Cynthia, a margrave’s daughter raised freely in the countryside, dreams of experiencing the kind of love she has read about in novels. Her home is known for having the kingdom’s finest army, but she has never attended an evening party in the royal capital until now. At her first party, Cynthia sees a duke’s son have his engagement broken off over an unjustified crime, at the hands of a selfish princess. Excited by the scene, she thinks someone cool and composed should step in to help—and blurts out a proposal of her own: “Then, please be engaged to me!”
