I've been watching you through social media all this time. Why did you betray me? My body is filled with emotions I could never express to you. You are my true "love." Just living under the same sky wasn't enough. I moved close to you, silently watching your every move. This is the story of a beautiful office lady named Nana, whose ordinary life takes a drastic turn when she's kidnapped by a perverted man and taken to his basement, where she's forced to endure his relentless advances every single day for one entire month.
