When she visits him in the hospital, Shinohara, who notices her condition, approaches her and she ends up allowing them to have a relationship... Later, she is called by Shinohara's friends, who use an audio recording of what happened in the hospital room to make her do embarrassing strip shows and masturbate. Their demands continue to escalate.
