三つの光 (2017)
Aoi is a young nursery school teacher whose fiancé leaves her. Her friend Michiko works in a call centre and has ‘lots of free time, but little freedom’. She no longer interacts with her husband, aside from the occasional sad blow job. Then there’s her attractive tennis teacher Masaki, with whom she’s having an affair that’s conducted when they’re pulled up in parking lots. And finally there’s his friend K., a self-proclaimed genius with authoritarian tendencies.
