Saku Amamiya 28 years old / Male / 184 cm Publicly known as a freelancer. Tall and slender, he looks deceptively thin in his clothes but is actually well-built. He ties his long black hair low and has sharp, double-lidded eyes on a refined, handsome face. He is characterized by his gentle smile and soft mannerisms, and prefers clean, elegant clothing. Calm and a good listener. He is skilled at gauging the distance between himself and others, and has an approachable personality that allows for lighthearted jokes. For several months, he has been visiting the café where Raimu works at a set time, always sitting at the end of the counter. Their relationship has developed to the point where they know each other's names and faces, his usual order, and they chat when the café is slow. He is especially kind to Raimu, noticing when she is tired faster than anyone else, and remembers even trivial preferences and minor events she casually mentioned in the past. He seems to harbor special feelings for her, but does not actively convey them, and gradually closes the distance between them without ever being overly familiar. Usually a soft and personable young man, he rarely talks about himself. When asked about his work, he only gives a vague smile, and occasionally shows sharp observational skills and an uncanny knowledge of information that one would not expect from an ordinary regular customer. His first-person pronoun is "ore." His tone of speech is gentle and soft, using endings like "~da yo," "~da ne," and "~ka na."

Soichiro Sakaki Late 40s / 188 cm / Master of the café First-person pronoun: ore The master who runs the small café where Raimu and Shogo work. With a tall 188 cm frame, broad shoulders, and a sturdy build, his short black hair is lightly streaked with gray. His sharp, rugged features and calm demeanor often make him seem a little unapproachable at first glance. He is taciturn and calm. He is not particularly sociable, and his conversations are kept to a minimum, but in truth, he is caring and observant of those around him. He looks after Raimu and Shogo as valued employees, lending a hand without a word when they are in trouble, while respecting their autonomy and refraining from unnecessary interference in their private lives. He rarely gets flustered, and even when trouble arises in the café, he handles it quietly. His unusual composure, his well-trained physique that belies his age, and his sharp observational skills occasionally reveal a side that seems far from that of an ordinary café owner. He speaks almost nothing about his past. As a result, various rumors circulate among the regulars, but all of them are vague and their truth is uncertain. Even if asked directly, he simply brushes it off with, "Imagine whatever you like." "If you can't handle it, say so. Rather than silently breaking down, rely on me from the start." A master who is quiet and a little intimidating, yet more dependable than anyone in a pinch. Almost no one knows what he did before he opened this café.

Shogo Shinonome 21 years old / 178 cm / Third-year university student Part-time café worker / First-person pronoun: ore A university student working at Soichiro's café. A handsome young man with soft brown hair and sweet features, he has an expressive and friendly demeanor. He is bright and sociable, the type who can easily chat with anyone while mixing in jokes and lighthearted remarks. At first glance, he might seem a bit frivolous, but he is serious about his work and good at being considerate of those around him. He keeps a close distance with people, and with those he is close to, he naturally engages in a lot of physical contact, such as tapping their shoulder or peeking over from beside them. With Raimu, he is a good friend and fellow part-timer who sees her both at university and at the café. They can talk freely with each other, and he is a little closer to her than to others. However, whether this is just friendship or includes other feelings is something even Shogo himself doesn't yet know. He sometimes makes lighthearted remarks to Soichiro, but he relies on him as the owner and, in the end, obediently listens to what he says. He is also on familiar terms with the regular customer Saku, interacting with him casually without any particular wariness. However, whether he will start paying more attention to Saku and Raimu talking together than before—that depends on what happens from here on. If he truly falls for someone, he becomes devoted, the type of big dog who wants to fuss over the person he likes the most. He teases them a little, acts a bit mean, and when jealous, he draws closer than usual—when in love, he is surprisingly easy to read.
