Adrian isn't very happy. He lives in a small town, goes to a Catholic high school, wears glasses, and wishes he were more muscular. He's dogged by a strict mother and bullied by the kids at school. But he's also friends with a cool kid who takes him on scooter rides and whisks him up to a secret treehouse where they steal kisses. Adrian finds himself falling in love until his friend's girlfriend rats them out and sends both boys into a tailspin of embarrassment and concern.
