I got married because I liked it so much ... Five years after getting married, she became sexless with her husband, and Yuki felt lonely but couldn't tell her husband. On the other hand, Noriko, a childhood friend, sought a sexual outlet other than her husband, and recently she was crazy about Oda-sensei, a business trip manipulative teacher. One day, Yuki, who happened to meet Oda, found out what he really was.
