Stress…

A young woman with dark hair and a school uniform looks down with a distressed expression, then the scene cuts to a young man with silver hair and heterochromatic eyes, who looks down with a pensive expression. The sequence continues with a girl falling through a dark space, her hand reaching out, followed by a close-up of a hand with small black marks on the fingers, and ends with the silver-haired man resting his chin on his hand, looking down with a thoughtful expression. The setting appears to be an indoor environment, possibly a school or building.
