Prompt:

"In the classroom, a girl wearing a sailor uniform is sitting on a desk, with her skirt lifted, revealing her underwear, and her expression is surprised. Next to her, a boy is sitting in a chair, holding a tissue, looking embarrassed. There are several empty desks in the classroom, with some tissues and a backpack scattered on the floor. Outside the window, the sunlight is bright, and the window is half open. Please redraw this scene, keeping the original setting and characters, but change the girl's expression to shy and the boy's expression to concerned. Also, ensure the image is more gentle, with a warm color tone, and add some details, such as decorations on the backpack and small items in the classroom."
