I've always disliked watching historical dramas because I found them to be boring. Silly me. I finished this drama so fast because it was so good and all the cliffhangers made me want to die. I heard this drama was really good and Kim Soo Hyun was the main character so what the heck why not! I have to say this drama is sad but VERT BEAUTIFUL. This drama has a fantastic cast. A round of applause to the child actors for doing an outstanding job. They can sure move me to tears. My heart was constantly broken for Yeon Woo and dang I thought Kim Soo Hyun already acted terrific. He takes it to a different level as being King. My heart also goes for Prince Yangmyung ): I thought every supporting character had some light and story and it contributed well to the plot. Character development and chemistry between all the actors were simply beautiful. This drama basically played with my emotions LOL but I for sure will be watching more periodic dramas from now on!
