Perhaps it's a story of a shy student who discovers a hidden talent for art under the bleachers. They start using that space as their private studio, away from the chaos of the school. They paint beautiful murals there, and eventually, their work gets noticed by the school art teacher, leading to an opportunity to display their art in the school gallery.
Under the bleachers could be a place where a young detective - a student, that is - finds a clue to a mystery in the school. It could be a mystery about missing equipment from the sports department. The student uses their wits and the clue found under the bleachers to solve the case and becomes a hero in the school.
