For Kanna Fuji's second anniversary as a Madonna exclusive, she finally takes on bondage. It begins with a phone call: after she mishandles a materials delivery for a major client, she is sent to apologize. The furious customer refuses to listen, so she desperately contacts every supplier who might have the missing materials. Chairman Kuroki spots her vulnerability and demands an outrageous price she cannot possibly pay. When she begs, “I'll do anything within my power,” he smiles as an idea occurs to him and approaches her, leading her into a punishing world of hemp-rope restraint.
