Kageko is a high school student who sees herself as unremarkable in all aspects of life. In the second semester, she is seated next to Mahiru, a well-known student and member of a famous idol group, whom she believes exists in an entirely different sphere. Despite their perceived differences, they are assigned to work together on the library committee. As they spend time together, it becomes apparent that Mahiru has a side that others are unaware of.
