Luo Jin returns to the Gu family after five years abroad, having left abruptly following a painful realization about her relationship with Gu Tangzhou, the heir to the Gu empire. She is an adopted daughter, taken in for superstitious reasons and raised as a subordinate within the household, perpetually reminded of her inferior status. Upon her return to the Gu family banquet, she is ambushed by Gu Tangzhou in a car, where he forces himself upon her with aggressive intensity. The encounter is interrupted when her phone rings, revealing that her cousin, Gu Qinghan, has detected something amiss. Luo Jin enters the banquet under duress, facing immediate hostility from her adoptive family, particularly Gu Qinghan and Fifth Madam Gu, who mock her past and question her virtue.
The core conflict centers on Luo Jin's desire for independence and her hidden investigation into her true identity, which clashes with the Gu family's exploitation of her. Fifth Madam Gu has arranged a marriage between Luo Jin and Chu Qinzhi, the disfigured and unstable second son of the Chu family, intending to use Luo Jin as a pawn to secure an alliance for Gu Qinghan, who loves Chu Qinzhi's elder brother. During the banquet, Luo Jin suffers from severe nausea, leading to rumors of pregnancy. Fifth Madam Gu drags her to a hospital for a check-up, where Luo Jin is publicly humiliated. Gu Tangzhou intervenes, citing the need for the Chu family to provide an explanation, which causes the Old Master to intervene and halt the forced marriage plans, temporarily saving Luo Jin from immediate disaster.
Despite this reprieve, Luo Jin is placed under house arrest by her adoptive father, Gu Fifth Master, who blames her for the failed alliance. The situation escalates when Gu Tangzhou reveals his continued control over her life, picking her up from the hospital and taking her to his private villa. He confronts her about her attempt to end their relationship five years prior, asserting that he never agreed to the breakup. Their dynamic is complicated by Luo Jin's lingering feelings and her discovery that Gu Tangzhou once showed tenderness to another woman, Bai Chuyan, which originally drove her away. Gu Tangzhou's possessiveness is evident as he monitors her movements and dictates her actions, yet he also protects her from her abusive family.
A key turning point occurs when Luo Jin, fleeing the hospital after her forced examination, encounters Chu Qinzhi, who harasses her and attempts to assault her. Gu Tangzhou arrives just in time to rescue her, displaying a protective instinct that contradicts his earlier coldness. He reveals that he orchestrated the cancellation of the marriage between Luo Jin and Chu Qinzhi by bribing Chu Qinzhi's father, Chu Tiankuo, to reject the alliance. This act secures Luo Jin's safety but deepens her entanglement with Gu Tangzhou, as he now holds the power to define her future within the family hierarchy.
The story direction shifts as Luo Jin is forced to stay at Gu Tangzhou's villa under the guise of recuperation. Gu Tangzhou maintains a tight grip on her, alternating between physical aggression and unexpected moments of care, such as treating her injuries from the beating she received from her adoptive father. Luo Jin remains determined to uncover the truth about her origins and escape the Gu family's control, but she finds herself increasingly trapped by her unresolved emotions and Gu Tangzhou's relentless pursuit. The narrative explores the power imbalance between them, the toxic family dynamics of the Gu clan, and the looming threats from external figures like the volatile Chu Qinzhi, setting the stage for a continued struggle for Luo Jin's autonomy and identity.
