I'm writing this for one reason only and that is to urge more people to watch this masterpiece. This is a rare gem, a phenomenal drama that deserves much more attention than it's getting. Well, to be honest, I think even a 10/10 ranking is not enough to do this drama justice!! It has one of the most intelligently written plots that one can ever come across. It's psychologically heavy and demands a mature audience. The drama chooses to look at its theme in a very philosophical manner; it chooses to take its audience to the core of a damaged human soul, and then slowly analyzes its each and every layers. As each layer unfolds, the audience learns more and more of the truth. To put it simply, this drama is about mistakes. However, what it focuses on is not the act of making a mistake itself, but rather its effects on both the person who's made the mistake, and the people who've been hurt by it. This might seem very simple, but in actuality it is profoundly complex. We watch the characters suffer as they fight their inner battles, the battles between love and hate, good and evil, right and wrong. We watch them as they crumble and still try to find their footing. Even though at times it seems futile, we still hope as hard as we can that they will survive this, that somehow everything would turn out to be ok. And I have to add this: what was very impressive was how in the midst of all this, the most humane feeling started to shine ... love; not necessary a romantic love, but the love that one can have for oneself, for the people around him/her, and for the life itself. The music was simply AMAZING, I cannot think of a better choice of music. Moreover, the acting was outstanding, specially the leads. Before this drama I didn't know any of the male leads, so their breathtaking acting took me off guard. There were times that the slightest change in their expression would make my tears drop or my heart to skip a beat. I recommend this drama to people who like to dwell in psychological mysteries. People who enjoy brilliantly written stories with meat to chew on, the ones that will leave you thinking not only for hours, but for days and months to come.
