It's a really sad drama! I couldn't laugh on anything, it was a very realistic drama with some surrealistic symbols. The whole movie's mood reminded me of Kumiko the treasure hunter. Single japanese working woman, who is almost a hikikomori, very depressed and despised by others just because she's not following the "marriage and make children" pattern. She goes away to America, a totally different culture, but after several disappointing events she returns to Japan with no idea how to continue her life... It's very philosophical, there are a lot of unspoken questions from the viewer "What's the point to live?...Is it love, or is it something else?..."
