An unexpected series to me. Never imagined it will blow me away. First of all, you find out it's a 24 episodes series and you might think it will be boring or drag too much but it's really not the case. One of the reasons is the depth and character development of all the supporting actors and not just the main lead couple. You will find yourself rooting for so many characters , you will be filled with a wave of emotions like no other. I cried like a river in the series, I laughed, I felt devastated, it made my heart flutter and squished. One of the gems of this show is it's music. A TRULY Amazing OST. Pretty much every actor in this show can sing. So many talented actors that gave the show some magic with their voice. I don't have to say much about the acting. It was very good. Some fighting scenes seemed a bit unbelievable but it's a fantasy series. My only drawback is that the female lead who was supposed to be seen as a boy to others, didn't look like a boy to me at all. If you have watched Coffee Prince you should already know how a girl who acts as a boy should really look. Other than that, no complaint. The story was intriguing and well written. I was moved so much by Choi Jin Hyuk's story line. Finally, you should definitely try this even of you are not a fan of historical series, like me. This show really deserves a second season, that's my only wish ^-^
