When the asshole finally left, Charles was finally able to breathe calmly and use the opportunity to explore the place he was in. He was worried that more than the planned time had passed, but he still remained here in this body and in this parallel world. However, being a professional, he hoped for the professionalism of his colleagues and decided to use the time for the benefit of science.
Struggling with the discomfort of his emerging assets, he tried to ignore it and focus on research. However, this was difficult to do. Long, disheveled hair constantly fell and blocked his vision and uncomfortably touched his face and shoulders. The chest seemed like some kind of foreign piece of flesh, which, although it was tightly pressed against the bras, was nevertheless very unpleasant.
Having found a computer and using the Internet, Charles soon realized that this world is not at all different from the one in which he was. However, there were still changes that he noticed other than being a woman here. Henry, Cheryl's husband, turns out to be working for the same special agency as Charles. He even held the same position as Charles. His theory that he gained Cheryl's knowledge was more and more like the truth.
He was finally convinced of this after he realized in shock that he did not know anything from his previous knowledge. He perfectly remembered his life as a special agent and all his actions, actions and feelings. However, he now had no idea how he was doing his job as a special agent. All this now seemed to him like memories from some movie in which the emotions and feelings of the hero, his actions and deeds are described in great detail. However, exactly how the hero of the film commits them has been overlooked in this film.
A few hours later it was already night and Charles felt that this body needed sleep. Plus, he knew Cheryl had to go to work tomorrow. Already realizing that he had received all her knowledge, he decided that he would use it and continue to pretend to be Cheryl for science and of course for the sake of being a hero. Naturally, he did not plan to tell all the details of this secret operation, but he would have to tell that he was in a woman's body as well as that he received all the knowledge of this woman. Although it was shameful, it was important for the study.
Reluctantly putting on Sherrill’s nightgown, he set the alarm and tried to fall asleep, hoping he didn’t have to go to Sherrill’s work tomorrow and pretend to be her.
