  "prompt": "A realistic photograph of a mathematics exam paper lying on a desk. The paper is filled with printed mathematical equations, algebra problems, geometric diagrams, handwritten calculations, and a few student-written answers. In one random corner of the exam paper, a student has casually doodled Phoebe from Wuthering Waves in pen. The doodle is a simple, charming, hand-drawn chibi sketch with minimal lines, recognizable long light-blonde hair, distinctive hair ornaments, and Phoebe's characteristic elegant appearance. The drawing looks like an idle student's spontaneous scribble made during an exam, with slightly uneven pen strokes, imperfect proportions, and a casual unfinished quality. The doodle is small and occupies only a corner of the paper, blending naturally into the surrounding exam content. The rest of the mathematics paper remains realistic and readable, with dense printed questions and handwritten workings. Natural indoor lighting, ordinary school desk, subtle paper texture, candid snapshot, realistic photography, top-down angled view. The overall image should look like a real student's mathematics exam paper with an unexpected Phoebe doodle in the corner, not a digitally designed illustration."
