A male student in a school uniform reacts with surprise as a smaller inset video shows a female classmate with long white hair; the scene shifts to a female student at a podium, then to a group of students, followed by a close-up of the white-haired girl bowing, then the male student embracing her with hearts floating around them, and finally a close-up of the white-haired girl with a man's face superimposed on her face. The setting is a school classroom.
