In Showa period, four tatami mats and half-floating tsuma (an affair between a man and a man in the middle of a school) was held by a thick masabori street called Ayayamaki.

A million-year-old floor laid on a damp, floating tatami mat, drops of faucet that fall into the flow of aluminum. The sound of a lively whisper that leaks from the closed four and a half tatami mat room, "Panpan" and "Anan." A turbulent chick who speaks of a man living in his neighborhood hiding in his husband. It was common for him to seek out his body hard with a man in an open space without his husband. One day, however, he witnesses Ki enter the house with a young man who is different from him. It was the evening of autumn without raining.
