Shot in the city of West Shinjuku, Tokyo.
I stopped at the lower level. And there was a stairway just in front of me. When I watched the staircase, I found two persons descending the stair. At first, I couldn't see their faces because of another stairway. The only thing I could see was their legs.
And I thought as if I was watching the backside of a pantomime. Unlike such performance, they didn't go back to the upper level. After descending, they walked away to somewhere.
