An elite doctor, Kuwahara, could not forget his feelings for Nanase Ren, whom he had loved in his youth. He subsequently changed hospitals one after another in search of her, and finally met her again at St. Cattleya Hospital. However, her attitude was distant, and his love could not be fulfilled. To make matters worse, he received a photograph showing Ren being molested. Ren had been turned into a lewd woman by Hirasaka through a female body experiment while she was at St. Julianna Hospital. He was disappointed and lost his mind. Kazama Mana, a nurse in the gynecology and obstetrics section, loved Kuwahara and resembled Ren. Taking advantage of her feelings, Kuwahara raped her and deprived her of her virginity, shouting Ren's name.
