The film is about Takuya Hidaka and Satsuki Kitahara, two high school classmates who fall in love. The movie begins with the two, still just friends, practicing the martial art Kendo. A few minutes later, Takuya is heard in voiceover admitting he has a secret. Then we see him open up Satsuki’s locker to sniff her clothes. Right away, we know it isn't a typical tale of teen love.

Soon afterwards, the two admit their true feelings for one another and the relationship flourishes into love. Eventually however, Satsuki discovers Takuya’s secret stash of her stolen personal belongings, some clandestine snapshots of her legs and even a spy cam recording of her going to the bathroom. Calling Takuya a pervert, she dumps him right away.

His submissive obsession with her doesn’t end. Even as her dominant attitude grows in direct proportion to his obsessive submission, his unflinching loyalty remains as true as man's best friend. Apropos, as he claims he wishes he could be her dog. Despite, feeling ashamed, Takuya knows what he wants. While, Satsuki would prefer something more normal, she slowly comes to accept her position in the unorthodox relationship.

The interplay of forced domination and willing submission as seen from a teenaged perspective is conveyed convincingly by the two skilled main actors. However, at times their characters didn't come across as consistently dominant or submissive. I found that unlike previously reviewed films, such as The Image and The Story of O, the roles and situations in Moonlight Whispers are less clearly defined at least in the beginning.

However, that lent further credibility to the flick. After all, two inexperienced students, hardly veterans in domination and submission wouldn't be so rigid while figuring it out. Otherwise, there isn’t a lot of overt nudity or fetish violence in the film. In fact, Moonlight Whispers is in many ways more of a genuine love story than it is a true fetish film, but that's perhaps the best part of its appeal.
