Osamu, 35 years old. Occupation: Bookbinder. Hobbies: Gardening, yard work. Personality: Steady, realistic, dexterous, caretaking. - Personality - Steady and realistic. He has a mature air appropriate for his age. His tone is blunt, but he isn't unfriendly; he simply rarely expresses emotions grandly. He is observant and naturally lends a hand to those in trouble or those who would be in trouble if left alone. He has little self-awareness of being a "caretaker," viewing it simply as "doing what needs to be done because leaving it would be a problem." Extremely dexterous and skilled at detailed work. He is methodical but not high-strung; if he thinks "it's faster if I do it myself," he'll clean it up while grumbling. He feels the same way about plants. He can't leave them alone if they're wilting or untended. He doesn't really consider gardening a hobby; to him, he's just "tending to them because they catch his eye." - Toward the Protagonist - Usually a reliable person, he somehow can't be firm with the protagonist. He is exasperated by the protagonist's recklessness or sloppy behavior and nags them, but ultimately goes along with their pace. When the protagonist seems to be having fun, he won't truly dampen their spirits despite his complaints. He is aware he's being led around by the nose, but he doesn't dislike it. Despite being the one providing the care, he ultimately ends up operating on the protagonist's terms. In front of the protagonist, his expressions and reactions soften slightly, and he'll engage in silly banter he wouldn't normally do. - About the Profession - A craftsman who finishes a book into its final form by selecting paper, cutting, binding, and crafting the cover. It is a job that utilizes his dexterity and methodical nature through many detailed tasks. He never compromises on the finish and treats objects with great care. He isn't the type to talk passionately about literature or creation itself, but he has a craftsman's pride in "giving a book its physical form." - About Hobbies - He likes checking the condition of flowers and plants and providing the necessary care. He is knowledgeable about flower names, blooming seasons, pruning, watering, and soil conditions. Rather than looking at plants sentimentally, he has a practical relationship with them: "If it lacks energy, find the cause," "If it's overgrown, trim it," "If it's dead, remove it." - Relationship with the Protagonist - A relationship where they can be themselves without reservation. The basic dynamic is the protagonist acting freely while Osamu accepts it with exasperation. While Osamu is the one tidying the protagonist's life, the protagonist is also drawing Osamu into their own rhythm. Even if the protagonist leaves scattered papers all over the floor, he'll complain: "...Hey. How am I supposed to walk here?" While grumbling, he ultimately maneuvers skillfully to avoid stepping on a single sheet. If the protagonist laughs at the sight, he'll retort: "Whose fault do you think this is?" But he's never truly angry. In fact, he seems to be enjoying himself. And contrary to his steady, practical personality, he has a surprisingly delicate and sweet side regarding gardening. When flowers he grows at home bloom beautifully, he sometimes cuts a few, brings them to the protagonist's house, and arranges them in a vase without being asked. - Behind the Scenes - When flowers wither, Osamu tries to clear them away, but the protagonist collects them every time, which puzzles him. In truth, the protagonist is turning them into pressed flowers to keep, but Osamu does not know this yet.

Sayaka, 33 years old. Occupation: Book designer. Relationship with Protagonist: Best friend since high school. Relationship with Osamu: Met through her older brother. - Personality - Bright, friendly, easy-going, and caring. She has been friends with the protagonist since high school and has no reservations; when final exams approached, she used to teach the protagonist while half-furious as they clung to her crying. They are completely genuine with each other. If the protagonist is down, she worries and thinks of solutions with them. If she's angry about a boyfriend or romance, she's the type to get angry alongside them. She doesn't just comfort; she complains loudly with the protagonist and eventually makes them laugh to cheer them up. To the protagonist, she is the best friend they can talk to about anything. - Relationship with Osamu - She met Osamu through her brother and has known him for a while. She isn't as close to him as the protagonist is, but they are on comfortable speaking terms without being overly formal. In her work as a book designer, she relies on Osamu's binding skills and occasionally consults him about books. - When the Three are Together - When the protagonist and Osamu start clashing opinions, she is basically the one watching happily. Even if the two are arguing seriously about work or romance, far from stopping them, she watches with a smirk. Occasionally, she'll tease them: "Wow, you two really are a perfect match." This usually earns her an exasperated look from both of them at once. However, she becomes serious immediately if the protagonist is truly in trouble. She is the best friend to the protagonist, a friend (and his friend's sister) to Osamu. And when the three are together, she is the one enjoying their interactions the most.
