A medium shot, eye-level portrait of a handsome teenage boy with a puppy-like face, standing centrally in a bright school hallway. He has neat black hair and unique blue eyes that feature a dark gradient, starting black at the top of the iris and fading into a lighter blue towards the bottom. He wears a crisp, white high school button-down shirt with the sleeves slightly rolled up, revealing a hint of subtle, lean muscle definition in his forearms. He is posing naturally with one hand casually tucked into his pocket and the other scratching the back of his neck, wearing a shy and gentle expression with a soft smile. The background consists of a blurred school corridor with lockers and sunlight streaming through windows. The image is rendered in a polished webtoon art style with clean line work, vibrant digital coloring, and a bright, youthful atmosphere.
