Rain at the glass door

Film a twelve-second suspense scene inside a secluded modern house during heavy evening rain. Begin behind an adult crossing a warmly lit living room toward a dark glass door. At three seconds, a faint knock interrupts the steady rainfall; the person stops, and the camera continues a slow push past their shoulder. Focus shifts from their reflection to a wet handprint on the outside of the glass. Hold for two seconds, then cut to an exterior reverse angle showing an empty porch and swaying branches. End on the person's uncertain expression through the window. Preserve the room layout and light direction, with no sudden apparition, graphic violence, or loud jump-scare sting.
