School life that is harassed and ignored every day. Akari-chan was bullied at school because she was a kind and weak child who couldn't speak her mind. Her homeroom teacher saved her. After that, her bullying disappeared suddenly, but in return, Akari became a sex slave according to her teacher. She's scared to go back to those days when she was bullied, but she's also scared of her pregnancy because her teacher always lets her inside... She can't refuse Akari-chan, who falls into the abyss without being saved.
