Use the exact backpack design from my reference image.
The backpack MUST look identical to the reference: same shape, same silhouette, same fur texture, same color tone, same pattern, same handle length, same zipper placement, same thickness, same softness.
Do NOT redesign or reinterpret the bag. Keep it consistent in all shots.
Create a soft, emotional 15-second winter scene of a real Japanese girl standing on the empty Shinjuku Station platform, waiting for the last train. Cold wind blows through the station as she rubs her hands and whispers 「寒すぎ…」. She reaches into her tote and touches her fluffy backpack, whose毛茸 texture matches exactly the reference image. The moment her fingers press into the fur, the scene softens and warms; the screen flashes white for an instant. As the white fades, the fluffy texture of the backpack expands behind her into a huge cloud-like field of the same毛绒材质, gently surrounding her back and shoulders—not a creature, not a person, just the same exact fluffy backpack texture forming a warm cocoon. She closes her eyes with a relieved breath and smiles softly: 「あったかい…」. The approaching sound of the last train grows, and the fluffy cocoon dissolves into small毛绒 particles that drift away. She opens her eyes, back in reality, as the train arrives. Cut to a close-up hero shot of the backpack from the reference image,毛绒 surface glowing softly under the station lights. Add simple white Japanese subtitles: 「寒すぎ…」 「あったかい…」 「ふわふわに包まれる感じ…」.
