Cinematic wide shot of a retro public bathhouse with green tiles. Thick white steam drifts across the water surface. A heavy-set man sits alone in the pool, relaxing with a glass of red wine placed on the pool edge. Quiet and atmospheric.
Tension scene. The man in the bath suddenly opens his eyes wide, looking terrified at something off-camera. Through the steam, a dark shadow moves rapidly towards him. He scrambles back, creating a large splash.
Symbolic ending shot. In the struggle, the glass of red wine on the edge is knocked over. The dark red liquid spills and swirls into the clear blue bathwater, spreading like ink. The water gradually calms down to complete silence. A white towel floats on the surface. 16：9 4k
