Looking for the name of the film.

A guy fells in love with girl who works in hairdressing salon. The guy follows the girl everywhere with video camera making he videos (then remaking these videos). The girl wears rosy sneaker that she lost during escaping from the guy. The boy finds the sneaker and returns it to the girl.

Thanks for help.

Does the movie end with the girl switching places with the guy and she in turn films him with her camera>?
