Lin Moyan, a paranoid gangster who suffered from the trauma of a tragic childhood death and was lonely for most of his life, has been in love with Shen Wanyin, the only person who can illuminate him since he was young. When the Shen family was in decline, he kept his beloved in the name of marriage and signed a three-year contract marriage. After marriage, he clumsily withheld his deep love, silently imitating the appearance that the heroine liked, and devoted all his tenderness to her. But Shen Wanyin's heartbeat fell, silently covering his heart. When the contract expired, both of them fell into low self-esteem, fear, and misunderstandings. The heroine took the initiative to submit a divorce agreement, completely defeating Lin Moyan's psychological defense. The male protagonist's collapse and self-mutilation, illness and madness, humble temptations, and the extreme misunderstanding caused by Chu Ci's appearance brought the relationship between the two to the bottom. Finally, at the last moment of their child's birthday and the divorce cooling-off period, the two completely let go of all their worries, resolved years of misunderstandings, and went in both directions to complete each other's lifelong redemption.
