To tell the true this show really surprised me in a good way and I can't understand why it is so underestimated. The second thing I don't understand is how the Korean television thought about making a remake of a drama where Kimura Takuya's character was undoubtedly one of the most remarkable elements :D To tell the truth it's my favorite Kimura's drama and not in vain I emphasize his role here: a quite unusual and unpredictable character gives him a wonderful opportunity to expose his peculiar charisma and good acting skills. Although, I give ten for the cast mainly because of Kimura as the other actors were really very mediocre. However it's one of the most captivating original Japanese series I've ever seen as you really find out things you haven't expected and also you have a powerful and also unexpected final. Also there are a lot of shadows in the characters' inner world whose lack I feel in many dramas. About the soundtrack, well, I can't remember it, so I think that it didn't irritate (what is really important as it doesn't happen so often) but also wasn't perfect for the drama as in the One Liter of Tears. However, the drama has a really strong atmosphere and wonderful male lead, so I can't quit the points to it.
