Iwasaki Noriko, a renovation contractor, appeared before Yamada Ichiro. She tried to persuade him to sign a contract, but since he had no intention of doing so, she resorted to using her sexuality. Though puzzled, Yamada gave in to the temptation. However, he was satisfied by Noriko's intense sex and ended up transferring money to her. Later, Yamada realized he had been set up, but he couldn't forget that night with Noriko. Through his connections, he found out...that Iwasaki was a pseudonym, and her real name was Nakameguro Junko.
