A clean, hard-edged anime-style illustration of a single young adult male character, captured in a combined low-angle and diagonal composition within a high-school classroom. He sits relaxed in a chair at the front-left section of the image, his left leg propped up on a wooden desk, torso leaning back slightly against the chair, while his right hand stays tucked casually in his pocket; his left hand holds a smartphone that he gazes down at intently, wired earphones connected and draped from his ears. His muscular, heavily-built physique is emphasized, gachimuchi aesthetic with broad shoulders, pronounced chest muscles, and thick arms. He has a medium-length wolf cut hairstyle with center-parted fringe, longer rear hair, and sides shaved into an undercut. He wears a loosely fitted white dress shirt unbuttoned at the collar to reveal his collarbone and upper chest, with an oversized black hoodie slipping off his shoulders in a worn fashion. Multiple silver earrings are visible on his left ear. Bright wooden desks and chairs, a chalkboard, and typical classroom fixtures form a neatly structured background. Warm, controlled color palette with subtle gradients and realistic lighting, firm linework, polished modern aesthetic, emotionally restrained atmosphere.
