Ex-girlfriend

A blonde anime girl in a school uniform raises her arm and smiles widely, then the camera zooms in on her sharp-toothed grin, followed by a shot of her making a peace sign outdoors, then a close-up of a different girl with long brown hair making a similar gesture, then the blonde girl's face is shown again with a manic grin, and finally the scene cuts to a close-up of a bicycle seat with Japanese text overlaid.
