Poor Cheng Yuanhai raised his daughter Cheng Jing. After marrying into the Zhao family, she endured endless torment. At the Zhao family's welcome banquet, Cheng Yuanhai, who had come looking for his daughter, was pushed down in public. His twin younger brother, Cheng Yuanshan, a big boss in Haicheng, arrived with a motorcade. For his seriously ill elder brother, he changed into old clothes, disguised himself as the poor father-in-law and entered the Zhao family, where he witnessed with his own eyes how his niece had long been bullied and threatened. From then on, every time the Zhao family made things difficult for her, he fought back forcefully. As the dark secrets of the past were revealed, Cheng Jing decisively divorced and broke free from her cage. What Cheng Yuanshan wanted to protect was never his powerful status, but to make sure his niece, who had suffered so much grievance, would never have to swallow her anger in silence again.
