Death over abandonment

This 50-year old narcissistic woman, a proper nutcase, Claire Millaud (Juliette Binoche), a professor in university, creates a new identity for herself as a 24-year old model entrepreneur and hooks up with a young guy in the internet and they both get overly excited with this new relationship based entirely on lies. It gets crazier by the minute and Claire needs therapeutic councelling. Another social media movie with pretty good twists to stay exciting.
