Plot
Around the time of late Joseon Dynasty when hierarchy between nobles and slaves started to fall apart and riots were common among peasants, two men were born on the same day and at the same time. Chun Dung who grew up in a beggar's quarters with no knowledge of his parents, dreams of "making this world a better place" by taking part in the peasants’ riot while Gwi Dong who was raised in a noble life, serves as a police official, fights against corruption within the government and speaks for the weak. Although both give their hearts to the same woman, they become the greatest duo ever in order to reform the problematic world. The background of the drama is not set in a grand palace but an everyday market and talks not of the success of a great hero but the agony of common people. The Duo portrays the everyday lives and loves of the commoners and outcasts during 19th century Korea: Slaves, beggars, leather shoemakers, thieves, street bums and butchers, people who were poor yet good at heart. It is centered on the humanism and sentiments of those whose life stories have often been neglected in the typical "royal family centered" dramas.
The Duo received solid ratings, averaging 13.0 percent on Total National Multimedia Statistics' chart and 16.7 percent on AGB Nielsen Media Research's poll, coming in first in its primetime slot several times during its run.
