Inhale… Exhale.

A blonde male student in a school uniform walks across a bridge, then the scene cuts to a close-up of a female student with long red hair, followed by a tender moment where the two students lean in to kiss under a tree. The sequence continues with the girl falling down a staircase, then the boy looking at her with a concerned expression as she appears to be crying. The setting is a school environment with outdoor areas, including a bridge, a tree, and a staircase.
