A high-angle medium shot depicts two adult sisters in their twenties huddled together in a stifling, six-tatami mat room of an old wooden apartment during a sweltering midsummer afternoon. The elder sister sits with her chin resting in her hand, her expression vacant and exhausted, while the younger sister lies prone, pressing her cheek against the floor; both exhibit glistening beads of sweat on their foreheads and necklines. They are dressed in light, summer indoor clothing, their mature figures leaning into one another for comfort. The room is cluttered with realistic details: a half-cut watermelon, sweat-soaked towels, melting shaved ice, an oscillating electric fan, open bottles of barley tea, discarded shirts, a desk lamp, stacks of manga, glass marbles, worn-out zabuton cushions, a peeling wall calendar, and a withered houseplant by the window. Soft afternoon sunlight filters through slightly fluttering curtains, creating a heavy, humid atmosphere with detailed shadows and smooth, glossy skin textures. The visual style follows high-resolution late-night anime original art with clean linework, gentle colors, and expressive eyes.
