Kawaibara-senpai wa Saotome-kun ga Suki!

Saotome is a short boy who's not very good at sports. He thought that he would at least be able to get good grades, but starting high school, he is far from the top rank, and he feels depressed because he has nothing else to offer. He is consoled by Kawaihara-senpai, the beautiful student council president who is like a "perfect girl" that excels in sports and academics. She tells him that she has been at the top of her class since the entrance examination, and she offers to help Saotome study. However, as a condition for her help, she wants him to wear a girl's sailor suit uniform when studying with her…

After school, a secret study session begins.
