When Yuan Rongjin, the eldest legitimate daughter of the Yuan Mansion in the Yuan State, was five years old, her stepmother Lin Huixian sent her to Jiangnan, intending to raise her to be useless, but along the way she was abducted by human traffickers. At a critical moment, Shen Anyi, the heir of the Shen Mansion, risked his life to save her, and Yuan Rongjin took a knife to the back to protect Shen Anyi, staying in the Shen Mansion ever since. Ten years later, Yuan Rongjin returns to the capital, and her stepmother and younger sister make things difficult for her in every possible way, while Shen Anyi always protects her well-being. In the end, Lin Huixian's conspiracy is exposed, and Shen Anyi begs the Emperor to bestow a marriage, welcoming Yuan Rongjin as his wife with a ten-mile red dowry procession. After enduring hardships together, the two finally become a devoted couple.
