I loved this drama so much it's the first and only I've watched through twice. A lot of people say it's over-rated, but I don't think it is. Where most dramas are pretty much the same thing, YB seemed to stand out and do something really different. The characters and the story were very unique. It was also really funny too, which is a bonus. I also discovered a band (FT Island) thanks to this drama (From Lee Hongki being in it). I think it's high rated for a reason. It's actually really good!
