Xu Anran runs a restaurant. Her brother-in-law, Cheng Lei, brings friends and family to consume 500,000 yuan over three months, yet claims his older brother's money is his own and refuses to settle the bill. Xu Anran demands payment, but her husband, Cheng Yuan, still urges her to make concessions. She returns to her pre-marital home to retrieve items, only to discover her mother-in-law, Sun Guizhi, arbitrarily using the house as Cheng Lei's bridal home. She takes the house back and refuses to back down. Cheng Yuan once voluntarily admitted his mistake, but after his younger brother's wedding hit a snag, he again demands that she change her story to cover up the facts. Xu Anran returns the key to their shared residence and decides to divorce.
