A young woman writes on a chalkboard in a sunlit classroom

A young woman with long, wavy brown hair is standing in front of a green chalkboard, writing on it with chalk. She is wearing a loose-fitting, light-colored button-down shirt with the sleeves rolled up. The shirt is unbuttoned at the bottom, revealing her legs. She is looking thoughtfully at the board, with her head slightly tilted. The setting appears to be a classroom, with a wooden desk and chair visible in the background. Sunlight streams in from a window to the right, casting a warm glow on the scene. The image has a soft, slightly diffused quality, with a shallow depth of field that blurs the background. The overall mood is one of quiet contemplation and a hint of playful allure. Cinematic lighting, realistic photography, natural pose, medium shot.
