Well, I kind of have mixed feelings about this series. In fact, drama covers all the main stories from manga/anime but on the other hand it skips so many important events. I almost felt like I'm watching a recap... But overall it was a good adaptation. From the positive aspects of course the music and the settings. I also liked Chizu and Ryu more than in anime. They played really good.
