Daughter, I'm sorry — Episode 13

Twenty years ago, Wang Guiying's daughter Sun Lanni and son Sun Tianhao were in a car accident. Doctors said only one could be saved; she chose her son. The daughter was adopted by the Zhou Group chairman. Twenty years later, Wang Guiying visited Sun Tianhao, his wife Zhang Manlin, and her grandson, but Tianhao refused to acknowledge her, driving her away with his family until Sun Lanni appeared. Later, when the grandson needed a bone marrow transplant for leukemia, Tianhao and his wife begged her. Guiying donated her marrow, they repented, and the family reunited.
