Japanese movie "好きだ、"

I watched the movie, "好きだ、" yesterday. The movie's time spent very slowly. First, I felt boring, but I kept watching and when I finished watching this movie, I like it. I decided to borrow it because Aoi Miyazaki appeared it. I like her because she is so cute and don't adorn her so much. The movie was written about people's delicate feeling and changing. I can't understand it perfect, but I can understand it little. (80 words)
