Brilliant software engineer and underground hacker Xu Rouyou is coerced by her greedy stepmother into attending a blind date with an arrogant, obnoxious suitor.

The stranger happens to be Lu Jingshen, the cold and feared billionaire tycoon running the city's most powerful corporate conglomerate. Taking advantage of the astronomical debt, Jingshen whisks Rouyou to the marriage registry, forcing her into a substitute marriage to satisfy his grandfather's demands. Rather than enduring a cold business arrangement, Rouyou finds Jingshen relentlessly spoiling her, using his vast influence to crush her abusive family and locate her long-lost birth mother. Yet as corporate rivals target Rouyou's hacking secrets, can Jingshen protect the spirited bride who stole his heart?
