On the day of Lin Shuang's wedding to her boyfriend, her mother-in-law learned that she was pregnant before marriage and deliberately took the opportunity to lower the bride price. Ma Bao's boyfriend blindly followed her mother-in-law's instigation and made things difficult for Lin Shuang. He also used the so-called "custom" as an excuse to publicly humiliate Lin Shuang and his adoptive father. Lin Shuang couldn't bear it anymore and decided to cancel the wedding. But the mother-in-law still refused to give up and instigated the guests present to continue bullying Lin Shuang. In the chaos, a shocking secret was accidentally exposed - Lin Shuang was actually her long-lost biological daughter.
