I remember watching this movie a couple years ago. It was about a teenager girl who wore thick shoes and she walked strangely or maybe it was a guy character who was her love interest. She was in the locker room where they change clothes for physical activity, and 3-4 girls stripped her down before a teacher came in and intervened. I remember later the leader of the bully group became friends with the girl she bullied who is the main character. Then they kissed for helping the main character kiss a boy at a party. That's all i remember. It was probably russian, ukranian, swedish, or something.
I can't find it anywhere :-/
