Yoon Eun Hye... she is my favourite, I think she is brilliant even when the drama is not the best.
I like Lee min Jung, too. In smile you she was really good.
Ha ji won is outstanding but I don't know about her acting in King 2 heart... perhaps is the north korean accent and I'm not use to. Ah! and Yoon In A, I love her since secret Garden, in Queen In Hyun's man her character is really differentand you can appreciate her skills.
And Lee Yong Ji, I think se deserved a main rol and I hope she get it soon.
Ah! A lot of people talk about Park Ye Jin, I knew her because of the family outing and I didn't like her face but then I saw Mr. Idol and I want to see more of her because she was the best in that movie, even better than Hyun Woo. After reading the comments, I made up my mind, i need to see other rols of her.
