A 17-year-old high school student, wearing a school uniform shirt and dark trousers, squats alone in a dark corner of the campus. His hands tremble as he holds a yellowed and worn notebook, on whose cover mysterious cosmic parallax patterns emerge, slowly blooming with blue-white light. The blue-white light pours out from between the pages, wrapping the boy's entire body. His eyes shift from surprise to calm focus; half-light and half-shadow carve across his young face. The surrounding walls and ground are illuminated by the blue-white light, forming strange light spots. Tiny light particles float in the air. Suspenseful and mysterious atmosphere, delicate light and shadow contrast, high-quality anime style, ultra-high definition, masterpiece.
