Twist & jerk

A young man in a school uniform reacts with shock and wide eyes as two female classmates, one with brown hair and one with dark hair, stand close together; the dark-haired girl smiles and holds the brown-haired girl's hand while the man reaches toward them, and the brown-haired girl suddenly opens her mouth wide in a scream. The scene takes place indoors, likely in a classroom or school hallway, with light-colored walls and vertical blinds in the background.
