In order to reclaim her parents' inheritance and escape the control of Jiang Junfeng and her uncle's family, Chi Ran offers ten million as a reward to find someone for a contract marriage, only to be rejected on the spot by Xiang Ye. When she turns to her best friend for help, she unexpectedly discovers that her best friend's older brother is the very man who rejected her just days before. The two obtain their marriage certificate, kicking off a two-month contract marriage. As they spend time together, Xiang Ye repeatedly shields her from the harassment of the Jiang and Chi families, and feelings of ambiguous affection gradually blossom. However, Chi Ran accidentally discovers that Xiang Ye's approach to her is connected to an old car accident case involving her parents ten years ago. A mysterious ancient painting entangles them in a buried secret; elders' plotting, rivals' entanglements, and age-old conspiracies follow one after another. Is this marriage that began as a transaction a mutual redemption, or a meticulously laid trap?
