One day, a married woman, Akane Soma, applied to appear in an adult video. She lives in Hiroshima and is now sexless with her husband, who is like family to her. Furthermore, she can't forget the sex she had with her ex-boyfriend. When I saw the photos she sent, my first impression was, "Why would such a beautiful married woman like that?" I immediately went to Hiroshima to meet Akane. The Japan-wide adultery documentary began.
