Haruka, a top-tier female area manager at the coffee shop chain "Biba," was known for her strict and uncompromising attitude—not only toward her subordinates but also toward store owners, earning her resentment from many. One day, owner Sawachi and subordinate Horio lured Haruka to a hotel, tied her up with ropes, and filmed as they took turns assaulting her. They intimidated her on-site, binding her body to crush her inflated pride, humiliating her until she was broken down and trained into a submissive female dog. This entire incident shook Haruka's strength and pride to the core.
