One day, Maki's husband, Daisuke, revealed that he was considering a department transfer due to repeated conflicts with his direct supervisor, Sugaura. Sugaura had once attended the wedding of Daisuke and Maki. One day, Sugaura visited Maki at her home and told her that Daisuke's future at work depended entirely on her decision. With those words, he handed her a strikingly radiant accessory and instructed her to wear it next time. However, this was no ordinary accessory—it was a special body ornament designed to be attached directly onto her body. Once worn, Sugaura treated Maki as his own possession, hungrily and possessively claiming her with dark, overwhelming desire.
