A medium shot from a slightly hig

A medium shot from a slightly high angle depicts a slender Japanese high school boy sitting alone on a polished wooden gymnasium floor. The boy is exceptionally tall and skinny with a bean-sprout-like build, featuring natural curly hair, round gentle glasses, and a healthy skin tone; he wears a white standard short-sleeved gym shirt and dark green thin cotton gym shorts with an elastic gathered waistband and wide 30cm leg openings that reach mid-thigh, exposing half of his knees. He sits with one knee raised, his hand resting flat on the floor, while his expression is gentle yet anxious with wandering eyes. The background is a detailed gymnasium interior with a polished floor and athletic equipment, rendered in a classic Japanese anime style. The visual style features crisp line art, cel shading, and precise anime lighting and shadows that create a clean, high-quality illustration.
