The movie has four named women (Heloise, Marianne, Sophie and the Countess) who talk to each other about love, music, mythology and only occasionally about Heloise’s nameless future husband.
It fails the reverse Bechdel test, since the movie doesn’t even have two named male characters or two male characters who interact.

The four main characters are women. Two secondary characters are women. There is talk of a marriage, but the groom is not the subject.
The film does not pass the reverse bechdel test.
