Initially because of the dire need for money, he accepts Teacher Kim's job offer but in the long run and his constant association with Kim Sa-bu, he realizes his worth as a doctor and the profession and starts admiring Teacher Kim who is the only one who was considerate to him when the whole world stood against him.
