The elite doctor Kuwabara Souichirou couldn't forget his feelings
towards Nanase Ren, whom he had loved in his youth. He changed the
hospitals he worked at, one after another, to look for her, and
finally he met her again at the St. Cattleya Hospital. However, her
attitude was remote and his love couldn't be fulfilled. To make
matters worse, he received photographs depicting Ren being molested.
Ren had been turned into a lewd woman by Hirasaka through the woman
body experiment when she was at the St. Julianna Hospital. He was
disappointed and he lost his mind. Kazama Mana, who was a nurse of
the gynecology and obstetrics section, loved Kuwabara, and she
resembled Ren. Taking advantage of her feelings, Kuwabara raped her
and took her virginity while shouting the name of Ren.
