An Chuer (played by Guo Biting) has been in love with her boyfriend for many years. The relationship between the two is very good. If nothing unexpected happens, they will soon join hands in the wedding hall and become husband and wife. However, at this juncture, An Chuer insisted on donating half of her liver to Yi Huatian (played by Zhang Ningjiang), a swimmer injured in a car accident. Her move directly led to her boyfriend's departure. The wonderful connection gradually brought An Chuer and Yi Huatian together. In the car accident, Yi Huatian lost a leg and was forced to bid farewell to the arena. With An Chuer's company and encouragement, Yi Huatian is determined to face the difficulties in life and stick to his favorite swimming sport. In the end, Yi Huatian finally won the Paralympic swimming championship with his own efforts. However, at this time, An Chuer chose to leave.
