Art style: Cinematic Realistic.
A 17-year-old boy with a cool and detached aura. He has messy, dark-brown hair with bangs that partially cover his sharp, intelligent eyes. He wears a navy school uniform styled loosely with the top button undone. He has a lean, athletic build and a sharp jawline. His presence is magnetic yet mysterious. He is often seen sitting in a relaxed posture. The background is a bright window with soft sunlight filtering through, creating a gentle halo effect around his silhouette.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
