It coincides with his wife's dystocia, and it is his bounden duty to take care of his benefactor's wife. All this was naturally misunderstood and dissatisfied by his wife. In a fit of anger, the wife went abroad without news, and did not let the lawyer go through the divorce procedures until two years later. After the father signed, the lawyer could not help telling him that the ex-wife already had a daughter. At this time, his father had been transferred to a small town in the north, and he took over the life of the deputy company commander's family, and formed a cozy family of three with the deputy company commander's widow and daughter.

A few years later, his father’s biological daughter and adopted daughter became Olympic contestants, and his father also faced the choice of whether to participate in the Olympics. Come to make up for the ex-wife.
