A beautiful short-haired girl with blue hair in a summer dress stands in a medium shot in a fantasy countryside summer night scene, surrounded by fireflies and distant fireworks. She has delicate features, large expressive eyes, and a melancholic smile, her head tilted slightly as she gazes softly into the distance. Her right hand rests gently on her chest, while her left hand hangs naturally by her side. She wears a light, flowing white summer dress with thin straps, a fitted bodice, and a knee-length skirt adorned with subtle floral embroidery, paired with simple sandals. The background features a lush rural landscape with rice paddies, wooden fences, a starry sky, and bursts of colorful fireworks; countless glowing fireflies float ethereally around her, their bioluminescent trails creating intricate patterns. Soft moonlight and firefly glow illuminate the scene with a warm, nostalgic blue-green palette, gentle bokeh effects, and a dreamy, wistful atmosphere.
