Su Wanning, the daughter of the Su family of a scholarly family in the south of the Yangtze River, made an ancestral marriage contract with Qin Jingming, the eldest grandson of the famous Qin family in the capital, since they were young. Even though the two had incompatible temperaments and Su Wanning was unwilling to do so, the marriage had been in stalemate due to the friendship between their ancestors and the face of the family. Until Qin Jingming's hotel room with a female star was accidentally broken up by Su Wanning, Su Wanning was completely heartbroken and insisted on breaking off the engagement. The Qin family refused to break off the marriage to protect the family's reputation, and the two families were in a stalemate. In the end, Mr. Su argued against all the opinions and proposed "replacement without exchange of marriage." The only children of the Qin family's age were Qin Jingming and his brother-in-law Qin Yanzhi, and Qin Yanzhi took the initiative to agree to the engagement. The two followed the traditional Chinese three books and six etiquettes and got married with ten miles of red makeup. From the initial respect as guests, they gradually became attracted to each other as they got along. Qin Yanzhi's gentle care healed Su Wanning, and Su Wanning's gentleness and purity warmed Qin Yanzhi. Finally, they started the most sweet marriage first and then love, and they stayed together for a lifetime.
