Gips 2001 (2001)

Kazuko bumps into Tamaki on the way back from work. Tamaki is crawling along the sidewalk on crutches, 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. Tamaki later dismisses Kazuko, throwing her a bunch of keys to the apartment and the cryptic comment "I can recognise a person who is meant to return".
