Sakuraka has been married to a classmate in college for several years. She usually spends a fulfilling day as a yoga instructor, but recently she has begun to feel passing by her husband. At that time, she became friends with Ozawa, a middle-aged man who came for a trial lesson. At first she was deliberately giving close-knit lessons as a distraction to her husband, who she wouldn't deal with. However, Ozawa, whose excitement does not subside, can not stand her close contact with her, and she covers her skin and skin exactly as she desires.
