Ten years ago, Lydia Young, David Sullivan’s wife, remarried a wealthy businessman for money, abandoning their daughter Daisy, who was only a few months old. Ten years later, Lydia Young’s son developed leukemia, and she tried to force Daisy to donate bone marrow. In his previous life, David Sullivan was persuaded by his family to agree, which led to Daisy’s death from illness and left him paralyzed and abandoned. Reborn back in 1990 on the very day his daughter was being forced to donate bone marrow, David Sullivan resolutely fought back against his family’s schemes, seized the opportunities of the era with his foreknowledge to build a business and become wealthy, consistently defeated his selfish family, punished the wicked, protected his daughter, and found a happy life.
