Divorced father Zhou Chengyue was deprived of the custody of his six-year-old daughter Zhou Xiaohe by his ex-wife Lin Suhua due to poverty. He humbled himself for three years, only to receive humiliation. Overnight, he made a huge profit of 300 million through the secret capital operation guided by Uncle Chen, and then returned to the battlefield in silence. He quietly acquired the Lin family's industrial chain and secretly funded Su Yutong's psychological intervention plan, just to make his daughter believe again that "Dad has not abandoned you." But when Xiaohe's diary reveals that the Lin family forged custody evidence, a shocking reversal of love and revenge has just begun.
