An elite employee at a major trading company appears honest and gentlemanly at first glance, but secretly becomes infatuated at first sight with a woman he meets through a dating app, luring her to his home. During their conversation, he gently disarms her guard with polite and caring behavior, inviting her to his place after dinner. However, after slipping a sleeping drug into her food, she loses consciousness. When she wakes up, she finds herself bound in a cold, sterile room, face to face with the man who once seemed so courteous—now wearing a sinister smile. She realizes the man, driven by an obsession with big breasts, is in fact a psycho path consumed by extreme possessiveness and lust. With no control over her body, she is subjected to his brutal domination, forced to confront nothing but terror as he begins his merciless assault.
