A cozy vintage library interior at night, warm and dim lighting, a classic fireplace burning with soft glowing flames, surrounded by leather armchairs and wooden bookshelves filled with old books. The camera is completely static, no movement, no zoom. Outside, it is raining gently, the sound of rain is clearly audible, creating a calm and relaxing atmosphere. The only motion in the scene comes from the natural flickering flames in the fireplace and subtle light reflections dancing on nearby surfaces. No people, no additional movement, no wind inside. The environment feels warm, peaceful, and immersive. Emphasize realistic fire animation, soft shadows, and ambient lighting. Add high-quality sound design: crackling fire and steady rain in the background. Style: ultra-realistic, cinematic, 4K, soft depth of field, warm color grading.
