"Breaking up is hard to do," goes the old song, and for some, it's so hard that they never quite manage it. A typical example is the partner (or, worst-case scenario, the spouse) who one day tells you they're back with an ex.

An atypical example is the couple in Shingo Matsumura's offbeat romantic drama "Love and Goodbye and Hawaii," winner of the Japan Cuts Awards at this year's Osaka Asian Film Festival.

Office worker Rinko (Aya Ayano) and grad student Isamu (Kentaro Tamura) are living together but are no longer lovers, having broken up several months prior. They're still friends, though, going out speed walking together and, at Rinko's insistence, racing each other to a riverside fence that acts as their own personal "finish line."
