A sensual drama depicting the distorted daily lives of two couples.

Yumiko lives with her son and former boxer Keigo, and is on good terms with her neighbor Ryoko. Ryoko is having an affair with aspiring novelist Mukai, but it seems to be approved by her husband. One day, by chance, Yumiko and Mukai end up having sex...

They’ve been drifting under one roof so long their hearts beat in half-hearted rhythm—he, a rugged chauffeur to the city’s most tempting “delivery health” sirens, and she, the depraved lunch-box artisan whose nimble fingers filled with quiet dedication. Yet fate tempts them both: he spends his days behind the wheel as a driver for high-end “delivery health” escorts, ferrying women who promise discreet thrills to private rooms, while at dawn she catches the gaze of a handsome regular at the bento counter, unleashing waves of longing so electric they could ignite the very air. The married couple are at a crossroad, their shared flat will feel too small to contain the wild forbidden desire roaring in the air.
