This drama is long overdue in my list. Basically, I heard great reviews but I just can't find time until today. In all fairness to this drama, once you start watching it, you can't stop. The story makes sense. I love the mystery. I love it when dramas made me think hard to try to solve the mystery (like CSI). Its the best part of this drama, solving the mystery. The way the writers plotted it makes you really want to watch until the end. Very clever. The acting was good but I have to admit, the 3 back-up of the crown prince were really funny. But I have to give the award to Lee Tae Sung (Yong Tae Mu) on this one. HE was so into the character that I hated him to the highest level. The music is okay but not the kind of music I will download in my phone. Overall, again, its worth the time and its worth the wait. I've given it 8.5 because I'm not sure about the tandem/love story side of it.
