This is a very amazing historical drama. The characters portrayed the roles very wonderfully and absolutely stunning. This drama is quite interesting and intriguing. Lee Joon Gi as Wang So and IU as Hae Soo has a nice chemistry. They are so good with each other; intense feeling. Their relationship shows that not all love story ends with a happy ending, as what everyone expected. Some may end up into tragic and this drama shows it. But still, they made us love their story. Lee Joon Gi's role is awesome, his words, actions and the way he glares, makes your knees went jelly. IU is so lovely and soft spoken woman, the kind of woman every men dream. And the Princes performed the actions and martial arts excessively. I so love their characters, they are so passionate and eager to give justice to each of the characters. They're incredibly awesome, made the scene meaningful and genuine.
