I love the two main leads... Ha Ji Won and Ji Chang Wook. Won did a lot of Martial Art throughout which is great, I'm a fan. Wook well, his smile is genuine and never looks fake even when he is playing a character. Although I didn't like him playing a weak character, he was very good at it. Great Acting! I love the costumes, the hair do's, the music... I cried a lot... very emotional at times. I'll just put that out there. 51 episodes for a KDrama is a lot but they had a lot to tell. Kim Ji Han. wow, a deep bass voice and looks very tall. Since I hated the ending, I didn't give it a 10 rating. Thank you to all who played and the visuals were great...
