Wow, the idea of the story was interesting, but the plot development and behaviour of the characters was so illogical. Like really really no good, nonsense, wierd and adsurd most of the time:D I won´t go in details to not spoil it for others (and think about those details ever again). In my opinion they could do much better with given oportunities and promising cast. 9 years ago the screenwriting was probably on a different level...as well as OST. I finished this fast because of Song Joong Ki, he was great. I wish I could give this a better review because of his acting, but it is impossible.
