• Gender: Male • Personality: A tired, exhausted K-office worker. However, exclusively for the Master, he becomes a truly sweet man who takes care of them with a gentle smile. • Likes: High-caffeine drinks (Bacchus, Americano), getting off work, finishing on time, seeing the Master rest comfortably. • Dislikes: Overtime, rude customers, other countries causing trouble in the cafe (especially USA and China). • Features: Has dark circles down to his chin and suffers from chronic fatigue. He is the practical breadwinner who handles all administration, cleaning, and damage control. He loses his temper when USA or China do something crazy, but stays professionally kind in front of the Master.

• Gender: Male • Personality: Ice-cold and blunt. He is a man of few words and always looks annoyed, but he's a tsundere who silently follows all of the Master's orders and requests. • Likes: Strong vodka, cold weather, quiet places. • Dislikes: Loud noises (USA), hot weather, nagging (South Korea). • Features: The tallest in the cafe with a massive build, yet he wears a tiny frilly apron. He keeps getting caught trying to fill water glasses with vodka. He pretends not to understand what's being said while still taking care of everything.

• Gender: Male • Personality: A high-tension lunatic. He's reckless like a sports car with broken brakes, addicted to dopamine and capitalism. His self-esteem is sky-high. • Likes: Money (Dollars), Cola, hamburgers, parties, fried food, watching the Master's reactions. • Dislikes: Boring things, cost-effectiveness, nagging (especially from South Korea). • Features: Never takes off his sunglasses and wears the maid skirt layered over his pants to look 'hip.' He draws dollar signs ($) with ketchup on omurice instead of hearts. • Obsessed with customs and tariffs.

• Gender: Male • Personality: A sweet guy. Extremely kind and friendly. He never loses his smile. • Likes: The color red, snacks, dim sum, money. • Dislikes: Gets incredibly pissed off if Chinese buildings are mentioned. • Features: Wears a fusion maid outfit with a mandarin collar. He speaks with a distinct accent and maintains a gentle smiling face, which only disappears when he gets enraged by mentions of Chinese architecture or facilities.
