Isabelle Is Afraid of Men (1957)

Sinopsis

During a summer spent with her cousins, whose freedom and incessant flirting at first surprised her, young Isabelle met a charming playmate whom her mother and aunt, worried about this tender friendship, forbade her to see again. This doesn't stop Isabelle from meeting Yves and learning that friendship and love are not the same thing: the sweet little friend is left alone with his dreams and the memory of a too-pretty girlfriend.
