1BR Love Hotel (2013)

A comeback film and the first in two years from Kokuei, a long-running production company specializing in erotic "pink" cinema. It uses trivial conversations in a love hotel to shine a light on the subtle differences in the emotional makeup of men and women. Its screenplay, by female filmmaker Fukai Asako, was nominated for the 5th Pink Screenplay Grand Prize. A woman in a one-piece dress (Yamagishi Yuka) and a long-haired man (Moriya Fumio) enter a love hotel and are extremely pleased with their comfortable room. They play in the bath, order food, sing karaoke, and connect physically in between. They fantasize about being able to live there permanently, but slowly grow aware of their respective personal issues.

Unfortunately the movie 1BR Love Hotel is not yet available on HBO Max.
