Kanzaki Saori's father ran a small town factory, but due to the recession, the company went bankrupt and had a large amount of debt. Her mother also suffers from a serious illness. Then a creditor makes Saori an offer.

Saori will be admitted to the private Tenma Gakuen, a girl's school in a dormitory system, as a tuition fee exempt student, and will introduce a part-time job for debt repayment. Saori takes the offer and performs the transfer procedure. In late July, the last day of a semester, she will transfer, and will go to the villa of the director Narusawa near the school for "the part-time job".

The villa of Narusawa, located on the Midorizawa Kogen, surrounded by mountains, forests and lakes, is a wonderful environment surrounded by dazzling greens, birds singing, and nothing more. However, the excitement did not last long. In the evening of the day Saori arrived at the villa, she's informed of the astonishing truth from Shiho of the underwriter: "You will work in a membership-only secret club and sexually serve rich men."

Saori, who thought that she would work as a housekeeper, cries and cries out in this too harsh reality. But after all, Saori is determined to "dedicate her body" to save her family.

Saori's days of hell began...
