Originally I was really reluctant to watch a historical drama, but this one had me hooked from the start. The actors are great, I love Park Yoo Chun, whom I had previously seen in Rooftop Prince and even Park Min Young was really good. They had great chemistry and played their roles really well. It's strange that it's another gender bender drama but it doesn't feel like one. I was excited to see each episode and marathoned the first half of this show. I fell in love with Lee Sun Joon but at times he frustrated the heck out of me, seriously how could they all mistake her for a man? I found the lead female was also really interesting because she was a very strong character. I liked that even the story had a lot of interesting plot twists but towards the end I got tired of the political intrigue. The only thing I didn't like, and it was a big one, that the end felt very rushed and the romance was weak. It had a great build up with great chemistry and when it finished I felt a bit let down. Overall though this is a really great drama that I'd definitely recommend watching.
