A blonde anime girl with green eyes and pink-tipped hair smiles at the camera, then turns and walks away on a sidewalk, her expression shifting to a joyful, open-mouthed smile as she looks back. The scene cuts to a different blonde girl in a white shirt eating a hot dog, then to a group of three students in school uniforms, and finally to a close-up of a character in a beige sweater with their mouth open in surprise.
