A medium shot of a beautiful, confident young woman with a "delinquent" (iljin) aesthetic, standing in a school hallway. She has long, styled hair and a rebellious expression with a slight, arrogant smirk, gazing directly at the camera. She wears a modified school uniform with an oversized cardigan draped over her shoulders, a short pleated skirt, and loose socks, with her hands casually tucked into her pockets. The environment is a sunlit high school corridor with lockers and blurred students in the background, creating a shallow depth of field. The lighting is bright and natural, with a modern, high-contrast color palette that emphasizes her sharp features and the crisp textures of her clothing, conveying a cool and intimidating yet attractive atmosphere.
