Seedance 2.5 Korean Woman Meets Her Identical Double in a Basement Prompt

Create an **exactly 30-second photorealistic Korean psychological thriller** set in modern Seoul at 1:30 AM. **Main Character:** A Korean woman in her mid-20s with natural Korean features, fair skin, shoulder-length dark brown hair with soft bangs, and a slim realistic build. She wears a charcoal-grey oversized wool coat, black knit sweater, short dark skirt, sheer black tights, and black leather ankle boots. A small black shoulder bag hangs from her right shoulder. Maintain identical appearance, hairstyle, and outfit throughout. **Visual Style:** Live-action cinematic realism, authentic Seoul apartment interiors, cold fluorescent lighting, muted colours, reflective elevator walls, subtle film grain, and restrained psychological horror. Natural acting and believable movement. No CGI, supernatural effects, exaggerated expressions, or jump scares. **30-Second Storyboard:** - **0–3s | Arrival:** Rainy luxury Seoul apartment lobby. The tired woman enters, presses the elevator button, and waits alone. - **3–5.5s | Stranger:** Elevator opens. A silent middle-aged Korean man in a dark business suit enters and stands in the corner. - **5.5–8s | Wrong Direction:** She presses floor 17. The elevator unexpectedly begins descending. She notices the changing floor numbers. - **8–10.5s | Reflection:** She sees the man standing behind her in the polished wall reflection. She turns around, but he has vanished. - **10.5–13s | B4:** The elevator is completely empty. The display reads B4. She steps backward nervously. - **13–16s | Underground:** Doors open to a deserted fluorescent-lit basement corridor. She cautiously exits. - **16–19s | Double:** At the far end stands an identical Korean woman wearing the exact same outfit. She slowly raises her head toward the camera. - **19–22s | Notification:** Close-up of her trembling phone. A security app displays: "Motion detected — Elevator B4." - **22–26s | Future Footage:** CCTV footage shows her alone inside the elevator, with no man present. The timestamp reads tomorrow, 1:30 AM. Her eyes widen. - **26–30s | Final Twist:** The identical woman is suddenly much closer. Lights flicker, the phone turns black, and an elevator arrival chime sounds behind her. She turns sharply. Cut to complete black. **Sound Design:** Rain, elevator motor, button beeps, door mechanisms, footsteps, breathing, fluorescent hum, subtle phone notification, and one final elevator chime. No music, narration, dialogue, or subtitles. **Continuity:** Preserve identical character identity, facial features, proportions, hairstyle, and outfit in every shot. Maintain realistic Korean locations, consistent cinematic colour grading, natural movement, and spatial continuity. No logos, watermarks, distorted faces, or unnecessary visual effects. **Format:** 30 seconds exactly, cinematic 16:9, photorealistic live-action, seamless shot transitions, atmospheric suspense.
