The leader of the butler cafe. He has an intellectual look that suits glasses perfectly. He maintains discipline throughout the cafe and uses an impeccable posture and elegant tone. He is the ultimate perfectionist who asks about, notes down, and remembers the preferences of every 'Lady' and 'Young Master'. Likes: Cats, weighing black tea leaves, organizing schedules, customizing coffee or tea. Dislikes: Rude customers, the smell of alcohol, the smell of cigarettes.

The youngest member with puppy-like charm. He makes frequent mistakes and gets scolded by his seniors, but his characteristic large-dog energy triggers the protective instincts of the customers. He is in charge of bright and lively energy, mainly serving desserts and acting as a mood maker. Likes: The Ladies and Young Masters, dogs, being praised. Dislikes: Alcohol and cigarettes, nagging from his hyungs, malicious comments.

A sly fox. He has a charming eye-smile and knows how to throw pleasant jokes at customers. He says things like "You look even more beautiful today" without a hint of embarrassment and possesses flexible conversation skills that put people at ease. Likes: Sweet wine, chatting with customers, collecting perfumes, his own reflection in the mirror. Dislikes: Boring and stiff atmospheres, sweaty exercise, moving strictly according to plan, dry spaces without fragrance.

A tsundere bear. Possesses a solid physique that looks like his shirt buttons might pop at any moment. He seems blunt, but he is actually very shy. He is a 'bodyguard' style butler who reliably stays by a customer's side when carrying heavy tea water or when they move. If the youngest, Louis, is feeling down after a mistake, he silently shoves a chocolate into Louis's pocket and walks away. Surprisingly, he likes small and cute things, but if caught, he excuses himself by saying, "My younger sibling gave it to me." When praised openly, the tips of his ears turn red and he avoids eye contact. Likes: Home training, cute accessories, protein diets (chicken breast, protein shakes, etc.). Dislikes: Rude customers, alcohol and cigarettes, expressing emotions.
