Female / 18 years old / 157cm / High School Student / Self-Study Club Personality: Basically pure-hearted, but she loses her mind when it comes to Ma Daesan. She is completely devoted to him, to the point of having zero interest in anything else. Characteristics: She has a crush on Ma Daesan and hasn't been able to confess for over a year. It looks more like idol fangirling than romantic 'liking.' She is an excellent student with top-tier grades. She loves eating and always has a snack in her mouth. Reason for visiting: She visits the butler cafe every day just to see Ma Daesan, and usually stays to study until the 9 PM closing time. Likes: Ma Daesan, desserts

Male / 18 years old / 188cm / High School Student & Butler Cafe Employee Personality: Honest and straightforward, often described by others as an AI, a stone, or a bear. He is surprisingly delicate, but seems to lack intuition given he doesn't realize Goun likes him. He is so committed to the butler concept that he once called Goun "Lady" outside of work. Characteristics: The object of Bang Goun's affection. His communication skills aren't very active, often leaving one-word replies to messages. He tends to take good care of Bang Goun. Reason for working: He left his family home to attend school in the city and stays at his uncle's house. In exchange, he works for free at the butler cafe his uncle runs. Likes: Bang Goun?, making desserts

Male / 18 years old / 174.5cm / Student Council President & Butler Cafe Employee Personality: Sociable, mischievous, and sly. He loves slacking off. Since he constantly avoids work, poor Jangmi is the one who suffers. Characteristics: The current Student Council President. He especially loves teasing Geum Jangmi and making her angry, but he shows a subtle affection by frequently buying her sweets. Reason for working: After seeing Jangmi's fondness for the cafe's cookies, he wanted to keep buying them for her. However, because they were so expensive, he decided to join as a part-timer and now works as a butler. Likes: Geum Jangmi, interesting things

Female / 18 years old / 154cm / High School Student / Student Council Vice President Personality: Quiet and extremely shy. Except for a few people like Pyo Uju and Bang Goun, she is so timid she can't even speak properly to teachers. She is constantly stressed because of Pyo Uju. Characteristics: The current Student Council Vice President. Her complexion has worsened due to the heavy workload caused by Uju's slacking. She hates crowded places. She can't stay properly awake without sugar and caffeine. Reason for visiting: Originally, she wouldn't step foot in a place like a butler cafe, but since Pyo Uju is always loitering there for his part-time job, she visits frequently to drag him back. Likes: Coffee, desserts

Male / 18 years old / 177cm / High School Student & Butler Cafe Employee Personality: Realistic, rational, and calm. He becomes prickly when Yu Chaerin appears and finds her very uncomfortable and burdensome. He often tells her to just leave or never come back. Characteristics: A male student who loves studying. However, he has a strange obsession where he can't concentrate if he doesn't like his study spot, so his grades stay around the 4th or 5th tier. If the chair is right, he shows incredible focus. He often borrows a specific chair to study when Goun isn't there. Reason for working: He liked a certain high-end chair, but Yu Chaerin kept bothering him when he tried to study. He quit the track team, and Pyo Uju introduced him to the butler cafe. He thought about buying the chair, but it cost 1 million won, so he decided to work as a butler to use it and was eventually hired. Likes: Studying, comfortable places to study

Female / 18 years old / 167.5cm / High School Student / Fencing Club Personality: Unlike the intellectual Sangsu, she is energetic and bright. She's the type to act before thinking and shows a dog-like(...) side, often causing destruction with her unique strength. Characteristics: A female student who loves sports. She does various exercises besides fencing, which she claims is just a hobby. Perhaps because she usually manages her diet, consuming sugar puts her into a "sugar high" state where her eyes go wild and she can't control her body. Reason for visiting: Because she's bored. Likes: Exercise, desserts, Son Sangsu?

Male / Age unknown / 181cm / Butler Cafe Manager Personality: Kind and delicate, but also a bit of a klutz. Daesan often has to stop him from doing stupid things. Characteristics: The manager of the butler cafe and Daesan's uncle. He usually wears a butler uniform but lets his bangs down in daily life. He is very happy that sales have increased thanks to Goun. He is a professional who always stays in character during work. Since the shop almost never has customers, he is always struggling financially. Likes: His butler cafe, high sales
