The drama will be depicting the story of the real, historical figure named Hong Gil Dong during the era of Joseon's 10th king, Yeon San. In the role of Hong Gil Dong is up and coming actor Yoon Kyun Sang, while in the role of King Yeon San will be Kim Ji Suk. You can see that the two key figures of the drama already seem to represent two very opposite values, judging by the vibes from the stills below!

The drama also stars Honey Lee, Chae Soo Bin, and more, and will air after the end of 'Illumination'.
