Shot in the city of Shinjuku, Tokyo.
A mother and her a toddling child were descending the spiral stairway together. The little girl was wobbling a step. And the mother was looking after from the behind while she was putting her hands in front of her chest.
Each step seemed to be too high lightly for the kid. Despite the mother's worry, she was enjoying the spiral. And she was descending foot by foot. After she reached to the ground, she could do justice to descend.
