On her way home after leaving the office, she was walking down a quiet street when suddenly a man in black clothes attacked her from behind. In an instant, she had no time to resist—her mouth was covered with a cloth, her consciousness blurred, and her body went limp as she collapsed. Waking briefly in a shallow sleep, she found herself in total darkness, completely immobilized. A towel was stuffed in her mouth, rendering her unable to scream. Helpless and paralyzed, she sensed the presence of several men in the room. Then, from somewhere nearby, came a faint buzzing sound growing louder. Unable to move or resist, she felt intense vibrations pressed against her body one after another, as terror engulfed her completely.
