Seven days left. Unaware of what's to come, office lady ○○ goes about her daily routine, oblivious to the leering eyes and escalating perversions of a stalker. From panty glimpses to locker room peeping, toilet voyeurism, and groping on the train, his obsession intensifies. He marks her skirt with semen, hides photos of her face covered in cum on her desk, and even sneaks into her home to record her phone sex. Finally, on the day of reckoning, he drugs her and forces her to swallow his semen, turning her into his personal semen toilet.
