I started watching this because Kim Soo Hyun was what made me like Dream High so much. 10 minutes into the first episode, I almost stopped watching this because I had never watched a historical drama before, nor had I had any interest in doing so before, but I continued watching to see if something caught my interest. 15 consecutive hours later I didn't want to sleep because of how AMAZING this drama is. I laid in bed at 5am and couldn't fall asleep because I kept wondering what was going to happen next. This drama was all I could think of. I've read some other reviews saying how good the child actors were, and they definitely do not disappoint. Everyone plays their part stellarly and I can't think of a better cast for any drama than this one. The last episode was definitely a tear-jerker for me at some parts. Once this drama was over, I was so sad. >
