Lina, long exploited by her stepmother and robbed of both her wedding dress and fiancé by her stepsister, hits rock bottom on her wedding day. On a rainy night, she encounters the reticent tycoon Kalen and enters into a one-year contract marriage. As antagonists relentlessly target her—spreading rumors, stealing her designs, staging incidents, kidnapping her, exposing the contract, and even committing arson—Kalen shifts from maintaining a guarded distance to openly favoring her. Meanwhile, Lina evolves from a passive victim of humiliation into an independent woman who gathers her own evidence, severs toxic family ties, and decisively crushes her adversaries. Ultimately, the contract marriage blossoms into true love, the villains meet their downfall, and Lina triumphs in both her career and her romance.
