The Perks of Being a Wallflower (2012)

Based on the novel written by Stephen Chbosky, this is about 15-year-old Charlie (Logan Lerman), an endearing and naive outsider, coping with first love (Emma Watson), the suicide of his best friend, and his own mental illness while struggling to find a group of people with whom he belongs. The introvert freshman is taken under the wings of two seniors, Sam and Patrick, who welcome him to the real world.
