Morita Mayu is a high‑school student. She is very quiet, and her silence combined with her habit of staring straight into others' eyes often leads to misunderstandings. It isn"t that she dislikes speaking or lacks things to say; rather, she over‑analyzes before voicing thoughts, missing the moment to speak. Nevertheless, she enjoys a joyful school life alongside her classmates, sharing laughter during recess and studying together in the library and in the evening club activities together.
