The love between a student and her teacher

Good evening,
it's the story of a student, she is blonde and a bit chubby, she enters a university she doesn't know, on her first day getting out of her car she gets her stuff stuck in the door, in the movie she falls in love with one of her professors, he is dark-haired and around 20, everyone makes fun of her, at the end of the film she goes out with her professor and they kiss on a baseball field. (the movie is at least 9 years old) thank you in advance :)
