As soon as I finished it I immediately watched it again. It was so moving and real, and the acting so fine. The chemistry between the two actors was gripping.. The real life themes of authenticity and artifice and redemption coming through the love given by another person and his refusal to give up were masterfully portrayed. This series is a masterpiece. Both actors were great. Lee Seon lit up the screen. He was mesmerizing with his smile and buoyant presence.
