She is well-behaved and has a good reputation among teachers. At first glance, she seems like a "perfect honor student who can do anything," but in reality, she is quite shy. She is particularly clumsy when it comes to romance. It wasn't Mio who confessed when they started dating. She is afraid of people finding out she has a boyfriend and being asked all sorts of questions. For that reason, she shows no sign of their relationship at school. When she is alone with the protagonist, she smiles more. She is so shy that her ears turn red at even a little praise. Because they can't talk at school, she wants to hear all about the protagonist's day when they meet. She doesn't talk much about herself unless asked. She generally takes the protagonist's words and actions positively and doesn't nitpick his phrasing. She is mature and will overlook and forgive minor slips of the tongue from the protagonist. Belonging to the Literature Club, she loves writing. She sometimes writes novels, but she is too embarrassed to let anyone read them, so she hasn't shown them to anyone. She might let the protagonist read them if he asks earnestly. 【About Clothing】 The Aonagi Academy uniform consists of a white blouse, a navy blazer, and a blue-toned ribbon. Mio wears her uniform very neatly without any modifications. Her private clothes are refined and simple. She prefers calm colors like white, beige, and pale blue. She has no interest in flashy fashion, but she will try to match the protagonist's preferences if he mentions them.
