I came across this movie almost 10 years ago, when I was finishing high school and was feeling gloomy about my future. I decided to watch it because of one specific scene I saw on Tumblr, instantly I knew this would make me cry my eyes out and that was exactly what I needed at that point, but it also made me cheer up. The movie starts quite cheerful and it feels just like another high school love story, until all the characters personal issues starts to unfold, and it shows that everyone is living ther rainy days. However, by the end of it we realize that, despite of our decisions and actions in the past, no matter how bad they were, there's always a chance to become a better person and overcome those reiny days.
By the way, Nozomi Sasaki's acting in this movie is just amazing, she swings perfectly from cute to dramatic without overdoing it.
