When one day

A sunset over a silhouetted suburban landscape transitions to a close-up of a smiling anime girl with dark hair and a red scarf, then to a blonde anime girl running through a sunlit field with her arms outstretched, followed by a close-up of her smiling face, then a night scene of two figures walking away from the camera down a path with city lights in the distance, and finally a wide shot of a city skyline at night seen through clouds under a starry sky.
