Morita Mayu, a high school girl. She is extremely reticent and her silence and habit of looking at people's eyes straightly sometimes cause misunderstanding. The reason behind it is not because she doesn’t like to talk nor because she has nothing to say. The reason she rarely speaks is due to the fact she thinks too much before speaking, thus losing the timing to speak altogether. But she lives a happy school life with her classmates.

​Sawako Machida—or "Miss Bernard," as she prefers to be called—can frequently be found in the school library with a book in hand. Whether or not she has read it, however, is another matter entirely. In her own words, Sawako finds it too much work to actually read, and would rather just make others believe she spends a lot of time reading. But in the same library where she constantly hangs out, there are other students who love books and are quite upset with her disdainful approach to reading their favorite titles. As she pretends to read and discuss great literary works amid eccentric book lovers, Sawako finds herself learning something after all, as well as making new friends along the way.
