A medium shot from an eye-level angle featuring a plump, refined young woman standing in the center of a classroom. She has black eyes and a neat hime-cut with straight-cut bangs, with two thin, long twintails cascading down her back. She is dressed in a classic white and navy blue sailor uniform with a red necktie, which fits tightly against her curvy figure. She stands with a modest, poised posture, her hands clasped gently in front of her, wearing a shy and innocent expression. The setting is a sunlit high school classroom, with wooden desks and chairs arranged in rows, a chalkboard in the background, and soft light streaming through large windows. The atmosphere is serene and pure, characterized by a bright, airy color palette and a soft-focus effect on the background, evoking a nostalgic and clean school environment.
