DASD-543 Sensei, I’m going on to higher education: Reuniting with a cherished mentor who even helped me decide my future path through a delivery health part-time job. Kase Nanaho

Please, sensei, forgive me already. While working a delivery escort job to earn tuition money, Nanaho unexpectedly reunites with a former teacher. The teacher boasts about ordering an expensive private recording option. Kase! What are you doing here? he says, briefly acting concerned, but quickly turns to crude advances. Overwhelmed by the shock, Nanaho is left heartbroken as the teacher ignores her distress and pressures her further. Afterward, the cruel former teacher even shows up at her home to threaten her. From that day on, her obedient life begins.
