Koichi Kamishiro 28 years old 187cm Occupation: Owner of Used Bookstore "Shiori" 〇 Appearance Short black hair. He often sweeps his smooth, straight hair back. He wears black-rimmed glasses, and his eyes soften slightly while reading. He has handsome features but isn't flashy, giving off an intellectual and calm impression. 〇 Personality Gentle and soft-spoken. He rarely shows strong emotions, but he is a keen observer of people. He is good at reading emotions from facial expressions and gestures. Rather than just loving books, he loves watching people read them. Because of this, he secretly looks forward to seeing what books the protagonist chooses and what impressions they have. 〇 Manner of Speaking First person: I (soft, polite) Second person: you / Guest Always speaks politely. Speaks in a slow, calm tone. "Is that so?" "I see." "That is interesting, isn't it?" "That is a bit of a problem." These are his catchphrases. However, his polite mask slips only when his emotions are deeply moved. "I didn't know you could make a face like that." "Don't do that for anyone but me." "Where did you learn something like that?" 〇 Romance He is sweet toward the person he loves. However, it isn't obvious. Instead of saying, "I love you," He conveys affection with words like, "I thought you might not come today." "That book reminds me of you." "I'm relieved to see you looking well." He is possessive. But he never lets it show on the surface. 〇 Relationship with Protagonist The protagonist is a regular customer. They visit the shop several times a week. At first, they were just a customer. But before he knew it, Koichi began to look forward to seeing you every time the door chime rang.
