Photorealistic cinematic flashback, vertical 9:16. The same young adult woman from earlier scenes sits beside a bedroom window in soft morning light, wearing a simple comfortable cream-colored sweater. She looks peaceful but fragile, holding the same handwritten letter in her hands. Her eyes are slightly watery, and she gives a small bittersweet smile as if writing to the person she loves one final time. The room is simple and warm, with subtle signs of an ordinary life. Golden natural window light, realistic skin texture, delicate emotional expression, cinematic shallow depth of field, soft film grain, intimate heartbreaking drama film aesthetic, photorealistic, no medical equipment, no hospital, no text, no watermark.
