Kaoru is obsessed with Kyoshiro's girlfriend, Tsumugi, and wants her for himself. The two men meet in a chat room and strike a twisted deal: they will take turns training Tsumugi to become a sex slave, documenting every step on a website.
As the training progresses, the site's visitors follow along, and at the end of the deadline, they will vote to decide which man deserves to be Tsumugi's boyfriend. The competition escalates into a dark battle of manipulation and control.
