A woman in her early 20s, dressed like an office lady, returns home and takes out a large bag, stuffing clothes and accessories inside while operating her mobile phone. From her conversation, it's clear she's preparing for new employee training. After finishing her preparations and phone call, she gets a bottle of water from the fridge and begins drinking—unaware that a drug has been secretly mixed in. Shortly afterward, she loses consciousness as a man breaks in and begins his teasing assault.
