Su Qingyuan married into the Yongning Marquis Mansion to replace her concubine. She thought she would have to face a sickly husband and a complicated back home, but she didn't know that {Lu Chengyuan} had already fallen in love with her. When her mother-in-law made things difficult, her concubine made trouble, and her relatives provoked troubles, Su Qingyuan resolved them one by one with her wisdom, never letting herself be wronged. Lu Chengyuan doted on her to the heavens and never showed any mercy when protecting his shortcomings: "Whoever dares to touch my wife, ask me first!" Without the blessing of a golden finger, the two exchanged their sincerity for their sincerity, trusting each other in the house fight, turning the "dry job of substitute marriage" into a life of sweetness and sweetness, writing a story about the sweet pampering and pleasure of the Marquis.
