After transmigrating into a book as the vicious fake heiress hated by the entire internet, Lin Wanxing finds herself from the start cleaning up the mess left by the original owner’s reckless actions: her scheme to frame the real heiress was exposed, and her family is now demanding that she apologize.
Knowing how tragically the original owner’s story ends, she decisively abandons the villainess act and just wants to stay away from the plot and live in peace. But one night, she runs into the bankrupt tycoon Gu Yanshen, who has been driven into a corner by the real heiress Su Yaoyao and the villain working together with the System. Struck by his dignity, and remembering how he secretly helped the heroine in the original book, she impulsively proposes a marriage contract: “I’ll support you for two years and help you get revenge and turn things around. You’ll be my shield. What do you say?”
With nowhere else to turn, Gu Yanshen sees that she isn’t as vicious as the rumors claim and agrees. One is a clear-headed woman who transmigrated into a book; the other is a patient, scheming tycoon. They begin as contract spouses in a mutually beneficial arrangement, but their sparks fly in their life together, and feelings gradually develop.
Faced with the System’s attacks on Su Yaoyao, her family’s misunderstandings, and the villain’s schemes, Lin Wanxing counters every move with her modern business savvy and knowledge of the plot, while Gu Yanshen carefully rebuilds his career step by step. From joining forces to punish the villains to standing by each other through life and death, their contract marriage gradually changes. By the time the truth about the System is revealed and the key to transmigrating into the book comes to light, the marriage that began as a deal has already become their firmest salvation.
In the end, the tycoon returns triumphant, the villainess clears her name, and the two stand together at the summit, crushing every enemy beneath their feet and beginning a sweet life in which they choose each other wholeheartedly.
