Aika Yumeno dreamed of becoming a swimsuit designer and joined the company with that goal, but due to economic downturn, the company's finances deteriorated, forcing her to assist not in design but in sales. Because of a senior colleague's scheduling mistake, a fitting session with a client went awry when the model failed to show up. Her boss coldly snapped, "Fine, you go then! We don't have time!" and shoved her into a revealing, highly sexual swimsuit against her will. Reluctantly, she had no choice but to take on the role of a model. Under the guise of modeling, she was subjected to intense sexual gazes and escalating sexual harassment, effectively becoming a sex slave for clients and coworkers alike, enduring repeated gang rapes. As her mental and physical state deteriorated, she gradually became addicted to the lewd stares and the thrill of group gangbangs. With her dream shattered, she adopted a reckless mindset—nothing mattered anymore—and sank deeper into this depraved world.
