Saimin Datsujo 4 ~Subete ga Boku no Jiyuu ni Naru Sekai e Youkoso~ Tennouji Karen Hen

Tennoji Karen is an aspiring idol who is currently in training. She is so busy studying and taking lessons that she hardly has time to sleep. Often, she dozes off in empty classrooms, where she meets Yuto. As a future idol, Karen has already attracted attention around campus. Through their secret interactions, they gradually grow closer to each other. Once, when Karen mentioned that she hadn't slept well and couldn't shake her fatigue, Yuto decided to put her under a hypnotic suggestion in order to help her get better sleep. Although it was only for a brief period, she managed to get a good night's sleep for the first time and was visibly affected by how refreshed she felt. After repeating this process several times, however, Yuto started playing tricks on her while she slept. Things escalated and he crossed a line. Their relationship continued, and it caught the attention of Saria Mikoshiba, a classmate and model who worked for the same agency. Saria saw Karen as a competitor and, sensing something suspicious, began investigating in hopes of finding something to use against her. Using hypnotic suggestions, Yuto revealed the truth to Saria and decided to teach her a lesson by making her reflect on her own actions. Unlike Karen, Sari actually had a secret lover, and Yuto made her believe that he knew everything about it. By manipulating her fear of exposure, he got her to do what he wanted. While enjoying his secret relationship with Karen, who was honest and earnest, Yuto found further pleasure in making the proud and stubborn Saria submit to him.
