Shinohara Mizuki is a high school student and fashion model who lives alone in a well-furnished apartment. His appearance, marked by bleach-lightened brown hair and a slender build, draws frequent attention for its beauty.

Mizuki’s life shifts when he meets Kazuomi Honjou, an adult businessman recently turned homeless. Honjou proposes staying with Mizuki in exchange for a sexual relationship, an arrangement that begins when he arrives at the apartment. Their connection deepens beyond the initial agreement. Mizuki, who often feels lonely and seeks attention through self-destructive acts, comes to miss Honjou during absences and values their nightly phone calls. Their interactions range from soft kisses to more intense physical greetings.

His modeling work involves long hours in uncomfortable clothing, which he finds tedious and sometimes frustrating. The job includes dinners and interviews with magazine staff. Mizuki’s brother assists him with practical matters, such as arranging early morning travel.
