Sunlit Korean Classroom Window Portrait

Realistic portrait of a [young Korean woman] standing beside large classroom windows in an empty [Korean classroom] during daytime. She poses naturally looking directly at the camera with a gentle smile, one hand casually resting in her hair, showing a relaxed, confident posture. Wearing a [fitted black ribbed long-sleeve scoop-neck top and light gray skinny jeans] with minimal elegant styling, a delicate necklace, subtle makeup, and long straight black hair with soft natural volume. Warm sunlight streams through tall windows casting soft shadows. A green chalkboard and South Korean flag are softly blurred in the background. Shallow depth of field, natural skin texture, cozy academic atmosphere, vertical composition.
