I have been meaning to write a comment ever since I finished this drama. I was really excited to watch this one and was anticipating a drama that would bring something different and new to the table.
It got of to a really good start, it was interesting to follow Ra Ons daily struggles and her interactions with the prince.
Since this drama, Park Bo Geum has really grown in my eyes, his acting was great. Sadly, I cannot say the same thing about Kim Yu Jeong. Maybe it's due to her young age but, especially in the latter part of the drama, I found her acting a bit stiff.

I think the ending left us with some loose ends, for example;
what happened to Cha Tae Hyeon and that lady that was seen in the first episode? The way it was portrayed made me think it was something major plotwise. That part has left me very confused since there doesn't seem to come a sequel.
