The drama tells the story of the life, love and struggle of Hong Gil-dong, a historical figure who actually existed during the reign of Yeonsangun. Yoon Kyun-sang plays the protagonist, Hong Gil-dong, a rare strongman who only appears once a hundred years after the founding of North Korea. Yoon Kyun-sang said, "It is my first time to play the leading role, and although I feel burdened, I still want to do my best to play the role of Hong Gil-dong. Because the character really existed, I am curious about him, and I have been repeatedly studying how to interpret the appearance of a revolutionary." by:xfplay5.com
