Shot in the city of Shinjuku, Tokyo. In the flow of the pedestrians, a mother wearing a cap stopped and crouched. A baby buggy was just in front of her and her cute baby was sleeping well on it. It might be dreaming. And the mother was taking care of it.
Everything around them was moving. So they seemed to be only existences which didn't move in the flow of time. After a short while, the mother started to move not to get left behind.
