The motive for the break-in goes beyond mere money. The two criminals have been targeting Kumi for a long time. They casually invade her home and immediately carry out their plan. Kumi cries out in shock and fear, but her screams are in vain. She is bound tightly with coarse rope and suspended from the ceiling, positioned so she cannot brace herself at all. In this state, the electric massage torment pushes her mental and physical endurance to the absolute limit. Kumi screams, her breathing becomes ragged, and ultimately she loses control and involuntarily urinates. At that moment, everything collapses, exposing her utter vulnerability.
