Story: The story is just amazing I always compare this to Bridal Mask nothing similar but...these 2 dramas were both really epic. There's a bunch of stuff going on in the story , so can't really explain. There's love, hate, twists and big character changes and surprises during the drama. After the first 3 episodes I garantee everyone that watched past these 3 eps will be hooked! Acting : I watched it for Song Joong Ki and Moon Chae Won. Song Joong Ki became one of my all time favorite actor after this. His character has so many sides to it. He's super smart and makes each episode have cliffhangers. His character is dark and deep, but he has a lighter side to him as well. Moon Chae Won has always been my favorite actress ever since The Princess' Man ...the whole cast just brings together the perfect amount of intensity and emotion. Kwang Soo did an awesome job as a friend here as well as Park Si Yeon. Music: it's XIAH Junsu and Song Joong Ki of course it's a 10. The opening is pretty epic too. Rewatch: I hate rewatching but I will watch this again one day
