Ou Yan's life transforms when her true identity surfaces after eighteen years within the Bai family. Exposed as the false daughter, she's banished to a mountain valley—only to find it's actually the nation's most elite residential enclave. Her biological family unleashes extravagant devotion: tens of millions in spending money, luxury vehicles from expansive garages, premium goods from across the globe. Elite schooling awaits, though she's free to skip it and manage the family business instead. The unexpected complication: her fiancé. Si Yechen, the world's wealthiest magnate, arrives requesting their engagement's dissolution. She's indifferent—until he begins pursuing her relentlessly. His touches linger, kisses claim hers, obsession consumes him. When confronted, she demands: "Who exactly are you?" His whispered reply: "Your husband, baby." She counters: "Only an ex-fiancé seeking freedom." The internationally feared billionaire stares in silence, mentally raging at whoever publicized a divorce announcement without them ever meeting face-to-face.
