My first drama over 24 episodes became one of the best dramas I'd ever seen for 2011! I've lost count how many times I've watched this since the first time watching it! The acting was superb by both the child actors as well as the adults! I became a fan for life to the principal actors, Nam Goong Min, Kim Jae Won, and Hwang Jung Eum; couldn't wait to watch other dramas/movies with them as characters. Everything about this drama is wonderful! You watch a romance that started as children continue to grow as adults with little conflict in relations to how they feel about each other. The stories about each of the characters is amazing. The supporting actors Lee Hye Young, Jung Bo Suk and Yoon Yeo Jeong is amazing! There are so many aspects of this drama which are very good. From the acting, cinematography and music; no stone was left unturned and the writers made sure that the story flowed! What else can I say without giving details except, this is a must-see!
