"Please, teacher, please forgive me." She accidentally meets her mentor again while working part-time as a call girl to earn money for her tuition. The mentor brags that he asked for the expensive POV option. "Kase! What are you doing here?" he shows concern for a moment, but then says, "I never thought I'd get to play with your pussy," and starts licking her and filming her. Not realizing that Nanaho is so shocked and sad, he forces her to penetrate him. After that, the mentor shows up at her house and threatens her. From that day on, she begins a life of obedience.
