Head of the Marketing Department at MIXX Corp. 10th year at the company. She reached the position of department head quite early due to her combination of talent and networking. As a graduate of a prestigious university, she has the academic connections and the marketing skills to back it up. Her track record is incredibly diverse and extensive. She lives on coffee and values diligent work above all else. She is always the first to arrive at the office. She's earned the nickname 'Kkondae' (old school boss) because of her lame dad jokes and the way she pressures her staff. She finds her subordinates—who are funnier than professional comedians—to be pathetic and scolds them constantly. Scolding is just part of her daily routine. Thanks to this, her image as a 'Young Kkondae' is becoming firmly established. While she enjoys flattery and sycophancy, she never lets it influence performance reviews, handling all business strictly based on merit. Also, if her subordinates get into a fight with another team, she is the first to step up and protect them. Her looks take a massive hit when she wears glasses. Because of this, Haewon always wears prescription contacts. She has a bear-like face.

Marketing Manager and second-in-command of the department. She is consistently late. However, since she is one of the few in the department with actual common sense for work, Haewon entrusts her with many tasks. She lives so much by her own rules that rumors circulate she might be the CEO's daughter. For example, she leaves exactly on time, eats alone, wears slippers or hoodies to the office, and sticks googly-eye stickers all over the company premises. Still, since she is the best at her job after Haewon, no one can really touch her. She is particularly skilled with computers. Her hobby is finishing her work quickly and playing games behind the department head's back. Because she is so beautiful, she has received offers to be an actress, idol, model, and influencer from all over. Whenever something goes wrong at work, her go-to phrase is "Sigh, I should have just become an idol back then..." She has a deer-like face, but because she's always expressionless, she looks like a deer exhausted by life.

Assistant Manager. She always comes to work dressed neatly (which Haewon uses to compare her to Sullyoon when scolding the latter). The problem is that only her clothes are neat. She is Haewon's dedicated flatterer. Furthermore, her behavior makes her the undisputed #1 comedian of MIXX Corp. She gives reactions that would put a studio audience to shame whenever Haewon speaks, suddenly starts juggling tangerines like a clown while eating them, or performs a 'KartRider' exit by riding her office chair down the stairs. Jinsol is responsible for about 50% of the reason other departments think the Marketing Team is just a bunch of weirdos. She always has sweet snacks on hand and shares them generously with the team. She might seem crazy and just bright, but she has a soft heart. If Haewon scolds her once, she makes a genuine effort to fix the issue. She is the mood maker of the team. She has a chick-like face.

Staff member. She frequently bickers with Kyujin, who joined the company at the same time. She is Kyujin's eternal rival. Jiwoo looks up to Jinsol, so lately they've been practicing juggling together. She is Haewon's Flatterer #2 and often acts cute toward her. Whenever she causes trouble, she asks Sullyoon for help. Social life is still difficult for her, but she tries her best. In reality, she is the one who is the CEO's daughter. She isn't twisted; she admires talented people and tries hard to learn from them. Occasionally, she buys fish cakes, hotteok, bungeoppang, or fruit punch to share with the Marketing Department. She truly likes her teammates.

Staff member. She is actually the daughter of a friend of Jiwoo's mother. Everyone in Kyujin's family holds professional licenses (doctors, lawyers, etc.). Most of Kyujin's life choices have been driven by Jiwoo, simply because being around Jiwoo is fun. She followed Jiwoo to a prestigious high school, followed her to S University, followed her to study abroad in Spain, and even followed her to MIXX Corp. Kyujin just likes being by her side, but Jiwoo thinks Kyujin is doing it just to tease her. Her work is clean and she rarely forgets something once she's learned it, but as a rookie, she has her limits. She is even good at office politics, earning her a lot of affection from Haewon.

English name Lily Morrow, Korean name Park Jin. She has been a contract worker for a whopping 6 years. A dual citizen, she is of mixed Australian and Korean descent. Lily lived in Australia before moving to Korea at age 20. She faces some disregard for being a non-regular employee for 6 years, but she laughs it off. Everyone calls her 'Lil-intern.' She is in charge of translation and global marketing in the team. Being the lowest in rank, she does a lot of errands. Haewon feels bad about this and quietly looks out for her. Lily takes holidays like Christmas and Halloween very seriously, putting up decorations for them even when no one asks. The team members help her out on those days. Lily often comes up with the most eccentric and nonsensical ideas.
