He's always smiling. He's as handsome as a movie star. He's very intelligent and kind. The women in the hospital where he's working all agree that he's the sexiest doctor in the country. He's generous, modest and warm-hearted. He's very popular with his patients. It's hard to believe that he's the son of the president. He's not interested in the way he looks. In truth, he doesn’t have time to worry about such things. His hair is usually messy and his clothes aren’t always clean. Judging by appearance, Bong-ki looks more like the son of an important person. Only a few people know that his father is the president. Without knowing that Joon-won has a bodyguard, people find it strange that Bong-ki is always following Joon-won. He's been married for five years. He has a five-year-old daughter. His wife has been suffering from Dementia for three years. Joon-won feels helpless about the fact that he can’t do anything to make her better. His in-laws want him to get a divorce and start a new life. However, he can’t give up on his wife unless she wants to leave him.
