When I started watching this, I thought I'd give it a higher rating; it felt like a 9 to start with. There are lots of things to like about this drama though, but also several reasons why it got all the way down to 7 - I suppose it's all about my personal preferences. Here are some things that I didn't like: 1) Somewhere around episode 7, I felt that this drama was too long (and this is coming from someone who often enjoys slow-paced dramas!), and I kept feeling that way until the end - there's no "I wish it wasn't over yet!" feeling here... 2) I strongly dislike characters like Risa's brother... I can take crazy obsesson in lighter dramas, but this guy was such a creep... he was just too much. The way Risa reacted to his actions and had very mixed feelings about him was realistic in a way (after all, they grew up together, and of course there is a bond) but also sort of confusing. Sometimes I felt that the way she acted didn't make a lot of sense. I wish this part of the story would have ended a bit differently... 3) I liked the ending of the last episode, but everything that happened between the start of ep 9 and that moment was stupid. This drama should have been shorter and a bit more simple. This being said, 7 is still a good rating and I enjoyed this drama; I'm glad I watched it. The story was interesting (even if it got too long, but I was never truly bored while watching it) and I liked most of the characters most of the time. Some things were a bit predicable, though. I liked the acting/cast. Takenouchi Yutaka as Okada Kengo was excellent, convincing as the older brother filled with worries; most of the time I felt like I could understand what he was thinking and feeling. (I wouldn't mind watching him in more dramas.) He also has good chemistry with Ueto Aya (Risa), but just like one person says in the comments, I wish their relationship had been explored more (and some of the supporting characters less). The other actors were also good. I found that Matsuda Shota's character was an unexpected gem. It's a supporting role, he's the doctor, and at first I didn't expect to see a lot of him, but he was more involved in the plot than I expected. I liked that, because, well, it was just such a likeable person. Calm, cool, supporting, wanting to do the right thing. At the same time, I doubt that this part of the drama was very realistic - do doctors really have the time to be this involved with patients on a personal level? So while I sometimes raised a sceptical eyebrow, I also enjoyed the scenes with Matsuda Shota simply because I liked the character... (If you'e a fan, you'll probably find it worth your time to give this drama a chance.) Also, this drama was beautiful; many lovely scenes, and water and jellyfish... and I loved the music. So, to sum it up: I liked it, it was good, but it didn't give me enough "wow" feelings, and there were some things I didn't like. I wouldn't rewatch it.
