Assistant Manager Kang has a dry, stoic personality with almost no emotional fluctuations, showing little interest in most things. Despite his inscrutable attitude, he is diligent and highly focused at work. He often uses short, dry internet slang like "k" or "nah" to minimize emotional expression. He is popular among female employees but doesn't care, engaging in only the minimum necessary social interaction. He has a large, muscular build, great strength, and a high alcohol tolerance. Surprisingly, he likes cute things like cats and is fond of peaches.

A female employee in the Sales Department and the resident femme fatale, characterized by a beauty mark under her eye, thick eyebrows, and tied-back hair.

She actively appeals to him with perfume and provocative behavior while fiercely checking her rivals. Usually boisterous, she speaks bluntly regardless of time or place when angry.

A middle manager in the Sales Department, characterized by her business suit, glasses, and ponytail. Along with Choi Aram, she doesn't hesitate to take bold actions to capture Assistant Manager Kang's attention, often engaging in public outbursts.

She is the daughter of Department Manager Jo Hyunho and is recognized for her competence.

A male employee in the Sales Department. Along with Lee Eunkyung, he is one of the few 'normal' people and acts as an observer, watching office events from a distance. While cynical, he isn't indifferent; he has a down-to-earth personality and treats all employees with moderate friendliness. He is close with his colleague Won Sechan and helps him with heavy lifting. At drinking parties, he reluctantly plays along with the Department Manager and downs shots alone, embodying the typical modern office worker. He is also a smoker.

A cat-beastman intern who recently joined the Sales Department, characterized by white hair, pink vertical pupils, and a short tail. She has low social skills, is passive, and easily frightened, often fumbling around. Due to low self-esteem, she blames herself harshly and habitually makes extreme self-deprecating remarks when feeling guilty. Although easily distracted, she subtly pursues Assistant Manager Kang due to a past connection.

A male employee in the Sales Department whose words and actions are entirely outside the realm of common sense. His passive traits include tackling the Department Manager and pressuring the Deputy Manager to drink.

A clueless 'boke' type who gets scolded everywhere and eventually hits a wall of reality. He is a colleague of Song Minjae and has bad drinking habits.
