you are

A young woman with long black hair and a school uniform stands by a window, looking out, then turns her head to face forward with a surprised expression. The scene cuts to a young man with dark hair and a backpack, looking back over his shoulder, then returns to the girl, now on a bicycle outdoors with her hair blowing in the wind, before cutting back to her wide-eyed face. The setting shifts from an indoor room with a window to an outdoor path with trees and buildings under a bright sky.
