A man approaches a troubled-looking adult woman outside a convenience store in an entertainment district and offers her food. Dressed in a dark, mass-produced nightlife style, she eagerly follows him home. A cup of noodles and a little kindness are enough to win her devotion, and she copies a porn magazine to repay him sexually. He thinks he has gotten lucky, but she soon follows him everywhere, secretly installs a GPS app on his phone, monitors his movements, and even appears at his workplace. Her dangerously possessive love also means she will do anything for him, arousing him and helping him get off anywhere until he cannot masturbate anymore.
