Gu Ci's accident while crossing the road caused Shi Qing's amniotic fluid to rupture. He was forced to accompany him to the hospital to sign as his husband, but he discovered that Shi Qing was the god-sister recognized by his father. Shi Qing was soft-hearted when she gave birth to a daughter out of wedlock, and the two gradually interacted with each other. Shi Qing fell in love with Gu Ci and took the initiative to pursue her. Gu Ci initially resisted due to seniority, but became attracted to her as they got along. Shi Qing chose to push Gu Ci away due to ruptured ovaries and was unable to get pregnant again. After Gu Ci learned the truth, he insisted on staying with her. He even unexpectedly discovered that he had donated sperm and Shi Ruanruan was actually his biological daughter. After going through many obstacles, the two resolved their misunderstandings and came together beyond worldly expectations. Five years later, the family of three lived a warm and happy life.
