Reflections of Thought: A Quiet Moment in a Café

A cinematic, photorealistic scene of a thoughtful young man with wavy auburn hair sitting alone at a wooden café table beside a large glass window. Warm golden sunlight softly illuminates his face as he rests his head on one hand, gazing out the window with a calm, pensive expression. 
The image is shot from outside the café through the glass, featuring gentle reflections, soft bokeh, and a slightly blurred background that creates a dreamy atmosphere.

Handwritten white chalk-style mathematical equations float across the window glass around him, as if visualizing his thoughts: integrals, limits, algebraic formulas, a quadratic graph, trigonometric identities, and E = mc². 
The equations appear lightly sketched, semi-transparent, and artistically arranged without covering his face.
The mood is intellectual, introspective, and peaceful. Shallow depth of field, soft natural lighting, cinematic color grading, warm tones, ultra-high-definition, 4K, highly detailed, realistic photography style, professional lens, soft film grain, gentle glow, modern aesthetic.
