A remodeling contractor named Noriko Iwasaki appears before Ichiro Yamada. - He offers Yamada a contract, but Yamada has no intention of doing so, so he appears as a gimmick, perhaps because he's annoyed. - Yamada is suspicious but is tempted, but he is satisfied with Noriko's intense sex and ends up transferring the money. - Yamada later realizes that he was framed, but he can't forget the sex he had with Noriko that day. - What I found out after making full use of the information was that Iwasaki was a fake name, and her real name was Junko Nakameguro.
