I liked the complicated romance between the main leads in this drama. However, the scenes given to portray it are not enough for me. I think it could have been more entertaining to watch if the characters actually got to interact more with each other and not just watch everyone from afar. I also agree with many others on the part that the child actors really raised the bar too high that when they grew up, only Kim Soo Hyun was able to reach my expectations. I also really loved Kim Yoo Jung and her acting. She perfectly portrayed a character that you know the characters will truly miss. Even in the later parts of the series, flashbacks to her few scenes had a very convincing longing effect.
