Lila Says (2004)

A self-styled bad girl leads a teenage boy down a frustrating path in this drama from France. Chimo Jarjoura (Mohammed Khouas) is a 19-year-old student living in Marseilles. Chimo likes to write and has genuine talent, but he hasn't been able to break away from his friends Mouloud (Karim Ben Haddou), Big Jo (Houd Dkhissi), and Bakary (Lofti Chakri), who are more interested in petty crime than in building a future and are suspicious of Chimo's non-Muslim teachers. One day Chimo meets a 16-year-old girl named Lila (Vahina Giocante), and is immediately smitten, especially when she makes it clear she's attracted to him. However, while Chimo falls head over heels for Lila, he soon discovers she's far more interested in talk than action, and that she isn't eager to limit her attentions to one man. Lila Says made its North American debut at the 2004 Toronto Film Festival. ~ Mark Deming, All Movie Guide

But in reality Lila's talk about other men is greater than what she says it is, even if she is a little over the top in exhibitionism. And these little lies lead to the surprise ending where Chimo finally sees what the true and basest forms of his friends. And he is finally free of them and has to decide what he will do with his life.
