Original title: 月光の囁き Gekkô no sasayaki

Satsuki (Tsugumi) and Takuya (Kenji Mizuhashi) are high school students who meet at kendo practice, where they bash one another with wooden swords. They begin an awkward romance, but Takuya soon reveals a masochistic side to his desires. He has been stealing Satsuki's soiled clothing and secretly surveilling her while imagining her subjugation of him. Disgusted, Satsuki rejects him -- but he persists, and she discovers her own pleasure in manipulating and humiliating him. themoviedb
