Mayu Morita is the protagonist of the series. She is a high school girl who is extremely reticent. The reason for her silence is not that she dislikes talking or has nothing to say, but that she spends too much time thinking about what to say. As a result, she often loses the right moment to speak and remains quiet. She has a habit of looking directly into people’s eyes, which, combined with her silence, sometimes leads to misunderstandings among her classmates. Mayu often tries to follow advice given to her by her mother, though these attempts are frequently misinterpreted by those around her. Despite her difficulty with verbal communication, she enjoys a happy school life and interacts with her friends in her own way. Her key relationships include her best friend Miki Murakoshi, who is very talkative and often the one who carries conversations; Hana Matsuzaka, a shy class representative who becomes a close friend; and Chihiro Miura, another friend who shares a fondness for sweets. Over the course of the story, Mayu’s classmates gradually come to understand her quiet nature better, though she remains taciturn throughout. Her notable trait is her intense concentration, which gives her an intimidating aura while she is thinking, but she is gentle and well-meaning. She does not possess any special abilities beyond her thoughtful, observant disposition.
