The story is nice and a classic shoujo topic even if it is going pretty slow, however, the main actress' acts were annoying for me. She acts like a 3-year-old child and it makes the story look fake.
I've watched many Japanese movies, including school-romance ones so I know how the story is going on so I can say that there are some disconnections during the movie and some scenes and the reactions were pretty weird (I mean the main actress) in this movie.
If you have much free time, it may be better for you to watch it. Otherwise, I don't really recommend it.
