Marion builds a fortress called rationalism to keep the world out. When an older woman dismantles it piece by piece, he discovers that what he called philosophy was just fear wearing a smart name. The movie doesn't let him off easy for learning this, it makes him pay for every moment of awakening, and that's where the real story begins.
Marion builds his entire identity around reason and logic, scoffing at sentiment as weakness. He treats emotion like a disease to be avoided, keeping everyone at arm's length behind walls of cold rationality. When a sophisticated older woman enters his life, she sees through his carefully constructed facade. Their relationship blossoms in ways Marion never anticipated, softening edges he didn't know he had. Under her patient guidance, he begins to understand that feeling something doesn't make you weak. It makes you human. But comfort has a cost, and Marion soon discovers that love demands sacrifices he never calculated into his equations. The affair that awakened him carries consequences that his newfound emotional awareness might not be equipped to handle. As summer approaches, Marion faces the painful realization that growing up means learning which prices are worth paying and which aren't. What started as a quiet awakening becomes something far more complicated and real.
