After graduating from women's college, Riko used her father's investment to open an esthetic salon, then married Kazuya, the heir to the Sawayoshi conglomerate. On the surface, she had a perfect life—but behind it lurked a dark shadow. Employees laid off after the closure of Sawayoshi Ironworks felt their dedication had been disregarded, fueling deep resentment. That anger ultimately turned toward Riko. She was kidnapped and imprisoned inside the factory, where her body was forcibly violated and abused. The horrific ordeal culminated in her being raped in front of her husband Kazuya, making the tragedy even more devastating.
