This is a nice drama about social stigma with some sweet romance on top. A man suffers discrimination and is ostracized in society because he has a brother who is in prison. I like how this movie doesn't paint this situation in black and white though. It shows how hard it is to survive in Japanese society, even if you are just guilty by (family) association with a criminal. But it also explains the reasons behind that mentality from, you could say, an evolutionary perspective. While this might not fit the current liberal Zeitgeist, it still makes sense. Some little things that happen storywise are a bit far fetched, but all in all it's a very enjoyable film with likeable characters.
