A nostalgic yet unsettling scene of (two high school girls in sailor suit uniforms:1.2) sitting by a classroom window. Under bright summer sunlight, they are (smiling and laughing together with squinted eyes:1.3), sharing a cheerful moment. Clothing translucent in the sunlight. Outside the window, a vivid summer landscape opens up with (massive towering cumulonimbus clouds in the bright blue sky:1.3). Crucially, there are (countless and random black handprints stamped all over the glass window:1.4) between them and the outside scenery. Detailed anime illustration, high contrast between bright summer nostalgia and an eerie atmosphere.
