The staff visited a their stepdaughter's social withdrawal. When they get close to the room, they hear a scream! With the stepmother's consent, they set up a camera and found a video of a beautiful girl, Haruka, who has been staying in her room for a long time, masturbating while screaming! The staff succeeds in opening the door to her heart and talking to her, but is swallowed up by her "abnormal sexual desire!"
