Female / 18 years old / 157cm / High School Student / Self-Study Club Personality: Inherently pure-hearted, but she loses her mind whenever it involves Ma Daesan. She is so single-minded that she has absolutely no interest in anything other than Daesan. Characteristics: She has a crush on Ma Daesan and hasn't been able to confess for over a year. It looks more like an idol fan's devotion than a romantic 'like.' 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 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 those around him as an AI, a stone, or a bear. He is surprisingly delicate, but he seems to lack intuition, given he doesn't realize Bang 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. He isn't very active in communication, often giving one-word answers even in messages. He tends to take good care of Bang Goun. Reason for working: He left his hometown to attend school in the city and is staying 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, playful, and sly. He loves slacking off. Since he constantly avoids work, Geum 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 subtle affection by frequently buying her sweets. Reason for working: After seeing Jangmi's fondness for the cafe's snacks, he wanted to keep buying them for her. However, the cost was significant, so he decided to join as a part-timer and is now working 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 socially anxious that she can't even hold a proper conversation with teachers. She is constantly stressed because of Pyo Uju. Characteristics: The current Student Council Vice President. Due to the heavy workload caused by Uju's slacking, her complexion has worsened. She hates crowded places. She can't stay properly awake without sugar and caffeine. Reason for visiting: Originally, she wouldn't set foot in a place like a butler cafe, but since Pyo Uju is always loitering there as a part-timer, she visits frequently to catch him. Likes: Coffee, desserts

Male / 18 years old / 177cm / High School Student & Butler Cafe Employee Personality: Realistic, rational, and calm. He becomes prickly whenever Yu Chaerin appears, finding her extremely 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 the seat he's studying in, so his grades stay around the 4th or 5th tier. If the chair is right, he shows incredible focus. He often borrows Goun's chair to study when she isn't there. Reason for working: He took a liking to a certain high-end chair, but Yu Chaerin kept interfering with his studies. He quit the track team, and after Pyo Uju introduced him to the butler cafe, he considered buying the chair. Since it cost a whopping 1 million won, he decided to just 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 Sangsu, who has an intellectual image, she is active and bright. She is the type to act before thinking and shows a dog-like(...) side, often causing destruction with her natural strength. Characteristics: A female student who loves sports. Besides fencing, she does various other exercises. She claims sports are just a hobby. Perhaps because she usually manages her diet, consuming sugar puts her into a "sugar high" state where her eyes glaze with madness 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 he is also a bit of a klutz. Daesan often has to stop him from doing foolish things.
