This is not a drama for everyone, especially not for ones like their dramas full of action and fast story development. This is a slow paced drama. However, this is a drama that I truly enjoyed. The story is controversial and many times I kept shouting this is wrong. Having said that I still kept on wanting to see more of it. It's a story of growth from emotional immaturity personality and character flaws. It's a story of love and sacrifice as well as overcoming weaknesses and self doubts; of wondering whether relationships are strong enough even when foundations seem to be breaking apart. I am so happy with the ending because it was not forced and all the characters were given a neat resolution. The acting was very good and believable. UTW made me feel every pain he was going through without him having to overact. LSH's acting was spot on. His personality suited his role. LSY was able to show me how her character has changed and grown in the 20 episodes of this drama. The supporting actors were also all so good. I liked the music because it did not take away from the drama but set the mood of the story. It was a great drama but I probably will not watch it again in the near future because of the slow pace. Watching this drama however made me feel like reading a very good novel by a really brilliant story teller; like Like reading Hemingway. I highly recommend to anyone interested in watching wonderful story unfolding slowly in 20 episodes.
