Snake Eyes

A young man in a school uniform holds a girl by the arms in a black and white, desaturated scene with other students in the background, then the scene cuts to a bright blue sky with white clouds and power lines over houses, followed by a girl with short brown hair seen from behind wearing a yellow vest, then a blonde-haired boy in a school uniform lying on the ground, then a girl in a green jacket standing on a tiled rooftop, and finally the same girl looking up in surprise as the blonde boy sits on the edge of the roof above her.
