A medium shot from a eye-level angle depicts a delinquent high school boy sitting in a classroom, leaning back in his chair. The boy is a teenager of East Asian ethnicity with a rebellious expression, featuring sharp eyes and a smug smirk; he wears a loose, unbuttoned school blazer over a white shirt, with his tie loosened and hanging haphazardly, and his hands are casually tucked into his trouser pockets. The setting is a Japanese high school classroom during the afternoon, with rows of wooden desks and chairs, a green chalkboard filled with chalk scribbles in the background, and sunlight streaming through large windows, casting long shadows across the floor. The visual style is a high-quality anime illustration with a warm, saturated color palette and a dusty atmosphere, utilizing soft sunlight and floating dust particles to create a nostalgic yet tense mood.
