I, the eldest daughter of the ducal house, was caught between my brilliant older brother, the next Duke, and my beautiful younger sister, who strongly resembled our mother. I was also the Crown Prince's fiancée. Until today, that is, when I was informed of the engagement's dissolution.

I had striven diligently, believing I would someday become queen, yet there she was: the rumored baron's daughter, standing beside my fiancé, the Prince. "You work hard, but that's all there is to it." These words, delivered by the Queen as a final blow, coupled with my father's decision upon my disheartened return home, invalidated everything I had lived for up until that point. As I cried myself to sleep in my room, I dreamed of a completely different world. "My past life?" This is the story of "the eldest daughter of the ducal house," who decided to sever all ties and live as a new self.
