Gips (2001)

22-year old secretary Kazuko first bumps into Tamaki on the way back from work. Tamaki is crawling along the sidewalk on crutches at a snail's pace, and stumbles into the young audiotypist after apparently having trouble with an ill-fitting shoe over her cast. After helping her back to her feet, Kazuko follows Tamaki back to her apartment, the two of them barely exchanging words. Once in Tamaki's room, Kazuko is dispatched on an errand to fetch some beer... Their game begins..
