Basically the story is pretty nice, is not the most original one but has good flow. The only thing I personally add about it is that in some point, there's too many problems or situation that you tend to be desperate as how is going to turn out (precisely for Shin Joon Yeong's condition -Kim Woo Bin-) About acting skills, most of characters are well developed, even Noh Eul (Suzy). Some people seem to criticise her acting skills but Suzy's character is not as demanding in script as Kim Woo Bin's character (although they have both tragic backgrounds) In the matter of music I loved it. It has a good selection and is very recognisable when you hear it. About watching it again.. NO. I was really tormented, the story is indeed a huge pile of problems and excruciating moments that I don't want to suffer again. I totally recommend this drama but watch it through only once. Most of people are very severe with this drama because of the ending. It's not what the majority wanted it to be and I believe it's also the reason why Kim Woo Bin came forward apologising for his choice in doing this drama (which I don't see why he has to, really. I didn't want it to happen either but you deal with it) I loved the drama.
