Song Chen and Lin Xue'er have been married for three years; Lin Xue'er seems gentle on the surface but is actually selfish and snobbish. After Song Chen discovers she has been diagnosed with liver cancer, his mother suggests setting a trap—having Song Chen falsely claim that he himself has cancer. When Lin Xue'er learns of it, she instantly turns hostile, and together with her mother she forces him to leave with nothing, seizing their marital home and savings, and divorcing him heartlessly. Thirty days later, once the paperwork is complete, Song Chen hands over her diagnosis report, and mother and daughter collapse. Lin Xue'er kneels and begs to remarry, then brings people to make trouble, only to have her misdeeds exposed by surveillance footage. In the end, Song Chen, remembering their past, covers all her medical expenses, but the two are never entangled again. Lin Xue'er's surgery succeeds, yet she has forever lost the person who truly cared for her.
