This is a great drama. This drama is well casted with excellent writing, directing and performances from the actors. The set design and wardrobe are beautiful. Although I think that Kim Yoo Jung is a fantastic actress, Hong Ra On should have been played by an older actress; her age gave a sense of fragility to the romantic scenes with Park Bo Gum (the Crown Prince). Besides that, there is great chemistry among the lead actors and the entire cast did a great job creating a very good drama. Enjoy it!
