This is my 2nd dorama! I watched it this year in January during my winter vacation. Prior to watching it, I had read the story in Wikipedia so I knew how it was going to end up as I have seen and heard several such stories. Yet I was curious to watch it because it seemed to be inspiring. I had lost inspiration to do my work and was in urgent need of it. And needless to say, this drama did inspire me a lot.
I love the entire cast. Whether the main leads or the supporting characters, all of them act brilliantly. There are many things about this drama that I love. Seeing the happy moments that Aya-chan (Sawajiri Erika) and her family have are a treat. Those moments made me smile. Not to mention, Nishikido Ryo has done an awesome job. In the beginning, I kinda didn't like him because he didn't show any emotions at all but later on, I just fell for him. The romance between Sawajiri Erika and Nishikido Ryo is simple and sweet. Romance doesn't need to be portrayed by hugs and kisses always. This drama also brings forth the low mentality of some people in our society, and how physically disabled people are looked down upon.
I gave this story a 9 because I was not satisfied with the ending. The last few minutes, I feel, were rushed. Also there is another fact about the ending which I dislike but I don't think it is correct to mention it here as it maybe considered as a spoiler.
The music is a full 10/10. I love the OST and whenever I listen to it, I become emotional.
I'd re-watch it someday but probably not now because every episode is fresh and vivid in my mind. I'll probably watch it again a year or two later when I'm in need of some inspiration.
Overall, this is a great drama series and it certainly should be in your list. Even if you hate tragic stories, you should give it a try.
