I only recently finished this drama, and it's so hard to put into words why it's so good! In the beginning, I was really unsure about whether or not I was going to like it. Ha Ji Won is excellent in this, but there were times when they were trying to juxtapose the soldier/warrior aspect of her personality with the feminine woman aspect that seemed a bit forced at times. Lee Seung Ki also did an excellent job in this role. It was very easy to hate him in the beginning, with his snide comments and attitude, I honestly thought there was no way I would fall in love with him. But of course I did! His smile and his genuinely good heart were impossible to resist. The other members of the WOC add drama and comedic relief to a show that can be really tense. For this only being Jo Jung Suk's second drama, I was shocked by how incredible he was, and that he wasn't snatched up for dramas a long time ago. As for the villain, Bong Goo is far from terror-inspiring, and tends to drag the show down a little bit because he is never really given a clear motive for why he wants to bring the royal family down, or why he hates Lee Jae Ha so much to want to completely destroy any bit of happiness he has ever had. Or why he is so obsessed with really stupid magic tricks! That being said, he eventually does seem to pick up a bit of rhythym that makes him a worthy adversary for Jae Ha. Also fascinating, the relations between the North and South. I can't claim a wealth of knowledge about the North, so I don't know how accurate any of their depictions are, but it definitely was an interesting look into the tense relations in the country, and how easily a war can be sparked. All in all, if you enjoy a big dose of drama, kidnappings, murder and attempted murder along with your romance, then King2Hearts is the drama for you! Just be prepared! It will make you cry like a little baby at times :p
