Yes this is a must see. You already know the synopsis, but after the first episode this drama is totally addicting, I was late for work, messed up on finals , stayed up till the crack of dawn to watch it. Although there is no romance , there is evil plotting, cool fights, love triangles, serious romance, and straight up tragedy. This is what I like to call a romantic tragedy because throughout the whole drama your heart literally bleeds for the characters. You want them to be together, you want them to have a happy ending but you do not know this will end. I believe that speaks volumes to the actors performances. First, Park Shi Hoo, who is hot, but wayyyy hotter when he goes to the dark side than when he is all smiles. (fangirl faint) He was incredible against Moon Chae Won who could easily have replaced and been better than anything that Koo Hye Soon is in. Two were believable lovers and just by their gazes you could tell what was up. In a side note I almost always hate Hong Soo Hyun because she’s always playing a evil chick, but that ferocity was good here. Character wise the characters were pretty stagnant, and I loved it. I absolutely hate it when the female lead is strong and speaks her mind in the beginning but in the end wimps out, but that doesn’t happen here and I loved it all the more. I could go on forever but, the drama is lengthy but not boring- I must confess to a little fast forwarding through the fights. A great historical drama that will not leave you wishing it was a modern day one. This drama really makes you question if love could ever really be like what you just saw on your computer screen.
