An intelligent beauty is trained and violated in a closed room. Taking advantage of the weaknesses of the targeted woman, they trample on her arrogant and high-handed self-esteem and force her into absolute submission. Even if her body is dominated, Kokoro will not yield. That is what she was determined to do, but her true nature is gradually revealed by the relentless torture of the barbaric men. Her vague masochistic nature is gradually revealed. The woman desperately tries to put up a false front so that she will not be found out, but she is tossed between humiliation and pleasure, and her true self is made known at the end of her disgraceful performance... In fact, Ai Mukai, who had always wanted to appear in the film, had already watched the series in her private life before she was offered the job, showing that she is a born masochist! The book contains four stories filled with these thoughts.
