Okay so I only remember the ending scene of this movie.
Basically the beginning starts off as a regular high school/teen movie and then I changed the channel and didn’t come back until the end, which shows the main character (male) being helped out of a car in front of the school by a girl. He’s now using crutches and his face is all bruised and he’s very obviously physically disabled. There’s really sad music in the background and he walks into the school with the help of the girl.
Pretty sure this was sometime between 2005-2010 but I could be wrong.
