Qin Yishuang, the eldest daughter of the Qin family, was involved in a staged accident and robbery five years ago. Huo Shimo, the eldest son of the Huo family, rescued her and then left for abroad in a hurry. Xu Jiqi pretended to be her savior, and since then Qin Yishuang started dating Xu Jiqi. However, he only regarded her as an ATM and took everything for granted. It wasn't until Qin Yishuang caught Xu Jiqi having an affair with someone else at home, and Xu's mother protected her son and his lover, that Qin Yishuang was heartbroken. That night, she went to a bar and accidentally met Huo Shimo, thinking he was a male model. After a one-night stand, Qin Yishuang left with one million yuan. Unexpectedly, Huo Shimo was a pure-hearted person who found Qin Yishuang through the cardholder. Learning that she was about to get married soon, he decided to crash the wedding. At the wedding, Xu's mother and Xu Jiqi humiliated Qin Yishuang, but she defused their attacks one by one and gave them two big gifts: a cuckold and a LIVE broadcast of his mistress having an affair with another man. Huo Shimo came in to crash the wedding but was looked down upon by Xu's mother and Xu Jiqi. Then Qin Yishuang found out that he was her savior, but Qin's father disagreed with their being together and demanded that his daughter enter into a marriage alliance, which was easily resolved by Huo Shimo. At this time, Grandma Huo appeared and asked Huo Shimo to marry Qi Fangyi, who had admired him since childhood, because she had saved Grandma Huo. Qi Fangyi didn't expect that the real person who saved Grandma Huo was Qin Yishuang, and she had sufficient evidence to prove it. After Grandma Huo learned the truth, she finally agreed to Huo Shimo and Qin Yishuang being together. He proposed to her and put a ring on her finger. From then on, the shining diamond became the witness of their Yimo time.
