Set in the Blue House (Korean presidential residence) this drama features the hard-working people inside the most unknown place in the country. Even though the presidential residence is the main setting of the story, the main characters of the story aren't the presidential family. The story focuses on the true residents of the Blue House; those who have always been in the very center of the history, but remained unrecognized for many years. We meet the presidential cook, kitchen staff, a carpenter, a photographer, bodyguards and other workers. These people are working in the most unusual and interesting place in South Korea. Nobody recognizes their hard work, but they strongly believe that the food they cook, the door they fix, and a phone call they answer can make a difference. They take their work very seriously and always do their best. The mini-series features the simple, but noble spirit of those who love their job and work hard. Therefore, the Blue House in this story represents the workplace of the hardest working people in the country, rather than the secret and off-limits presidential residence.
