In order to get rid of the fate of being dependent on others, the orphan girl Su Wansi set her sights on her cousin Xue Zhili, the eldest son of Xue Guogong. She skillfully dealt with the struggle between the crown prince's concubine Su Miaoyan and her cousin Shi Yilan. The prince was disgusted with her scheming at first, but he discovered her intelligence and tenacity in one incident after another, and his emotions turned from pity to love. After going through many tests such as drugging, assassination, and fire, the prince saw through his disguise but loved his truth even more. In the end, he obtained the imperial edict for her, and the matchmaker married her. As an orphan, Su Yuansi relied on her wisdom and strategy to finally win the crown prince's true heart and the status of the mistress of the Duke's palace, achieving a reversal of fate.
