I thought this story was refreshing. I'm not a fan of historical dramas, but in this case I didn't mind at all. The only thing I found a little disturbing was the pairing of Yoon Shi Yoon and Kim Sae Ron as a love interest. I just couldn't get over the fact that she is still very much a minor in real life. However, outside of that, I really enjoyed the drama. What I liked the most is that you didn't spend every episode saying, "Oh my god, that person is so evil, how can they keep getting away with fill-in-the-blank and no one picks up on it." You know those dramas where the bad guy/girl has such a complex evil plot and everyone is just too blind to see it. Well, here the evil is clearly evil, everyone knows they are evil, and the reason why they keep getting away with it is plausible. The casting was fun. From (Welcome Home!!!) Yoon Shi Yoon who played the ultimate devoted man to the plucky Kim Sae Ron, the ridiculously lovable Lee Yi Kyung and his perfect partner Do Hee, Evil's Evil Step-Mother Yum Jung Ah and the endearing, emotionally torn Lee Sung Jae....it was fabulous. But the icing on the cake was throwing in some final episode cameos by two of my all time favorites Ahn Kil Kang and Kim Kap Soo. I literally squee'd. The music was typical OST. Nothing to write home about so I scored it in the middle. And as for rewatch value, also lower because I don't really see myself watching the series again. Watch this if you don't like historical dramas but want to dip your toe in the water, if you love a good, slow-building bromance story and if you missed Yoon Shi Yoon while he was serving.
