The value was changed from A drama portraying the lives of doctors who struggle to bring happiness to families and children, "Good Doctor" deals with the pediatricians who save the lives of young children through a steadfast sense of duty and the pain and agony these doctors face. The raw, uncut reality of a pediatrics department bound to be substandard due to the upper management's strict pursuit of profit and a completely illogical insurance system. The actions of the doctors, who take responsibility for the children's futures rather than just simply treating them, make one rethink the question of what adults must truly do for children. "Good Doctor" attempts to show that those with disabilities have feelings and dreams just like everyone else and that they are actually beautiful people who can touch the hearts of all. It delivers a message saying that what these people need is not sympathy and pity, but a sense of belonging, appreciation, and recognition as a member of society.
