Mr. Lee tells his son, who is now a physics student, that he has been neglecting him since he divorced his mother. When he finally had time to care for him, he realized that his mother was an artist who would give up everything in order to pursue art. He says that his son has suffered a great deal because of him and his mother, who drove him away from him and made him hate him very much. He also says that he won the physics competition this time and that he showed him the certificate, but that day, he said that he had not won the prize. He asks his son if he can be his son only if he is good at everything, and he says that if he does not, then he is not qualified to be his mother's son.
