Yuya has liked Kokoro since he was in elementary school. Recently, she met him again by chance, and when he confessed his feelings to her, they started dating. In fact, Yuya's father was a teacher, and she was their homeroom teacher. Yuya brings Kokoro to her home and makes her meet her father once again as her lover. However, she does not notice that her father's lewd gaze is fixed on Kokoro's large breasts. I have a question about Yuya.
