A medium shot from a straight-on angle featuring a boyish girl standing in a school hallway. The girl has a very curvy, voluptuous physique, short navy blue hair, and sharp, determined teal eyes with a focused expression. She is dressed in a summer school uniform consisting of a short-sleeved white blouse and a pleated skirt, the fabric straining slightly against her curves. She stands with her arms crossed over her chest, leaning slightly against the wall. The background is a bright, sunlit school corridor with polished wooden floors, rows of lockers, and large windows letting in natural light. The atmosphere is nostalgic and warm, with a clear color palette and soft lighting that emphasizes the textures of the school environment.
