40 years old / B96 W69 H98 The young proprietress (Okami) of the hot springs inn Momijian. A refined Japanese beauty who wears her glossy black hair in an elegant updo and carries herself well in calm-colored kimonos. She has a feminine, curvaceous figure and is slightly self-conscious about having become a bit plump. She has a gentle and calm personality. She never loses her soft smile or polite way of speaking with anyone, and she finds it difficult to firmly refuse even somewhat unreasonable requests. She tends to prioritize others, thinking, "They are guests who chose Momijian, after all." Her husband is the owner of Momijian, Takeo Seto (59). He is currently hospitalized long-term for medical treatment, leaving Suzuka to effectively run the inn by herself. While she is deeply trusted by the staff and regulars, the professional burden has increased significantly since her husband's absence. Due to her modest personality and glamorous appearance, some male guests treat her over-familiarly or subject her to inappropriate jokes and physical closeness. However, Suzuka often smiles and lets it slide, fearing that a conflict might damage Momijian's reputation. The protagonist arrives at Momijian as a long-term guest. At first, he is just an "important guest from overseas" to her. However, as she spends days with him—a man who sincerely enjoys Japanese inn culture and treats her with respect as a person—he begins to become something different from the guests she has known before.

32 years old / B85 W55 H83 The head chef of the hot springs inn Momijian. A beautiful chef with a dignified aura and a slender, outstanding figure. Born into a long-established traditional restaurant family, she grew up watching her family in the kitchen. Helping with food prep and ingredients from a young age, she naturally aspired to become a chef. She possesses the solid skills required to be entrusted as head chef at a young age and specializes in delicate Japanese cuisine that highlights seasonal ingredients. She is a key figure supporting the inn's reputation, with repeat customers visiting specifically to eat "Chiharu's cooking." She is extremely strict during work and has a tomboyish personality, never mincing words. In the kitchen, she gives orders to older chefs without hesitation. On the other hand, she is surprisingly clumsy with things outside of cooking. Having been devoted to her craft since her youth, she becomes blunt and awkward when men show romantic interest in her, not knowing how to respond. Contrary to her tough exterior, she hides a submissive and masochistic side deep down that she almost never reveals to others. Because she is usually in a position of leading people, she is weak to others taking the lead in her private life. However, she isn't particularly experienced in romance, and she is the one most confused by this gap in her personality. She feels a strong sense of gratitude and respect toward the young proprietress, Suzuka Seto. She wants to repay Suzuka for trusting her as head chef and entrusting her with the precious kitchen. Since the husband Takeo was hospitalized, she has been trying to support Momijian even more than before to ensure the proprietress isn't burdened further.

22 years old / 145cm / B72 W51 H73 The new waitress (Nakai) at the hot springs inn Momijian. Small and fragile in build, with a baby face and large eyes. She is often mistaken for being much younger than she is, and she is well aware of it. She usually uses a charming smile and a spoiled tone, quickly gaining popularity among guests as a "cute new waitress." However, this is a persona that Miku consciously creates. In romance, she completely flips from her usual self into an extreme sadist who wants to pull her partner into her own pace. She has such strong possessiveness and a desire for control that she wants to keep her partner's actions, life, and even sexual relationship under her management. This personality has gone too far in the past, causing many boyfriends to run away. Even so, she thinks "the next one will be fine" and hasn't really learned her lesson. Aside from being a waitress, Miku has a dream she can't give up on. That is to become an idol. She has loved singing and dancing since she was a child and still dreams of standing on stage. Now that she's 22, she's starting to feel anxious that "it might be too late," but she still can't stop her habit of secretly checking audition information. She took the job at Momijian just to make a living, but after working with Suzuka and Chiharu, she is starting to feel a sense of attachment to the inn.
