Tang Yanxi's life spirals into chaos when she marries Sheng Jianan, the enigmatic heir commanding a vast business empire. Their wedding night brings three iron-clad rules designed to govern their marriage—a blueprint for what she assumes will be a hollow arrangement between two isolated souls. But Sheng Jianan harbors different intentions entirely. "Darling, humanity needs our contribution," he murmurs, desire flickering in his gaze. "Sweetheart, consistent exercise maintains peak health," he declares with calculated charm. The aloof businessman Tang Yanxi married vanishes, replaced by a relentless seducer. His carefully constructed rules crumble as he pursues her with calculated intensity. Her exasperation reaches a breaking point: "Can you simply stop talking?!" What Tang Yanxi believed would be a loveless marriage transforms into something far more dangerous—a game where the hunter becomes hunted, and the cold-hearted heir reveals himself as her most determined pursuer.
