My legal mother sold me to an old man for wedding luck. I sent her own daughter to prison in return, and finally married the prince.

My elder female cousin relied on her status as the legitimate daughter and snatched my engagement with the young lord. She even sneered at me, "How could a concubine-born girl ever be worthy?" I smiled and conceded the marriage to her. Yet soon after, I married her former fiancé — the cold-faced general mocked by the entire capital for being ill-fated to his wives. On our wedding day, she finally realized the truth. The young lord was nothing but a penniless nobody, while the general was the emperor’s most trusted confidant. Three years later, the general was conferred the title of marquis, and I became the marchioness. Cast aside by the young lord, my cousin knelt before the marquis mansion gate and begged: "Dear sister, let us swap our fates back." I replied coldly, "You once said I was unworthy. Now who is the unworthy one?"
