Normally when I watch japanese live actions or movies, I don't quite pay attention the OST, however the OST soundtracks for this film was great. I initially watched this because the main role acted in many other films that I've watched and he's a great actor. However, the storyline was interesting and the casting was nice. I cried once throughout this whole movie so it's not too emotional. It's a cute, short school story. I recommend you watching this and I haven't read the manga for this so that might be my next step.
