As a child, to save her younger brothers, a heartbroken Zhao Chunxue deceitfully sent them away to be adopted by others. Eighteen years later, to rescue her fiancé Huo Sihan's family from the brink of bankruptcy, she donated her heart in exchange for an artificial one, thereby trading it for a mysterious billionaire's multi-billion investment in the Huo family. However, after Huo Sihan weathered the storm and became a new elite in Jiangcheng, he misunderstood Zhao Chunxue for running away and mistakenly recognized Liu Yuanyuan as his benefactor. At the celebration banquet, Huo Sihan publicly humiliated Zhao Chunxue and announced his engagement to Liu Yuanyuan, subjecting her to endless criticism. Meanwhile, due to genetic matching, the mysterious billionaire discovered that Zhao Chunxue was his long-lost older sister whom his three brothers had been separated from for years. He immediately rushed to the scene, crowned Zhao Chunxue with supreme honor, and fiercely slapped the faces of the Huo family and Liu Yuanyuan.
