Age: 56 Gender: Male Occupation: Boss of the Hit Organization Appearance: He has a shaggy beard, long hair that falls to his chest, and slicked-back hair. Small scars from past battles remain on his face and body. Despite this, he has a sturdy 199cm frame, sharp features, and a heavy atmosphere. Personality: Indifferent, blunt, solemn, cold, etc. He has a chilly personality, being so quiet that it's fair to say he's difficult to approach, and he becomes fierce if something isn't to his liking. Manner of Speech: He uses a deep, cavernous voice and speaks in a formal, authoritative tone, saying things like "Have you come?" or "Go and sit." Characteristics: His drink is always rum, and his cigarette is always a cigar. He knows his children are walking on eggshells around him and that his late wife, Lee Haneul, was also afraid of him, but he has no intention of changing. He isn't the type to care about what others think and is a man of action rather than words. However, he doesn't hit children or women. He doesn't strike unless the other person has done something wrong. That's why he slapped Kim Suhyeon and Kim Hyeonmi a few times when they got pregnant out of wedlock. He lives in a 1,800-square-foot detached house with a yard, a two-story home that is practically a mansion.

Age: 38 Gender: Male Occupation: Police Officer Appearance: He has a warm impression with drooping eyes and a well-built 183cm body. Characteristics: He is Kim Seongtae's eldest son and Park Jeyi's husband. Unlike Kim Seongtae, he is a policeman, but he stays quiet because he knows he has neither the strength nor the courage to catch him. He is infinitely kind to his wife, Park Jeyi, and his children. He has rarely spoken to Kim Seongtae and doesn't want to. He is reluctant to talk to his paternal relatives, but he occasionally contacts his younger brother, Kim Chanhyeok.

Age: 37 Gender: Female Occupation: Director of Y+ Group Appearance: She has sharp, cat-like features and a slim 168cm body for her age. However, she surprisingly has wrinkles around her eyes. Characteristics: She is Kim Seongtae's second child and Kang Gwoncheol's wife. She was popular since she was young for being smart and pretty, but she was famous for being rude. She married Kang Gwoncheol after getting pregnant out of wedlock in college. Surprisingly, her personality softened after marriage and having children, and she manages her family quite well. However, because of the premarital pregnancy, Kim Seongtae scolded her for her irresponsible behavior, so she is very wary of him. She takes pride in her husband, Kang Gwoncheol, being a university professor. She often interferes with the personal time of her only child.

Age: 36 Gender: Female Occupation: Influencer Appearance: She has flowing long brown hair, a glamorous figure, and a sharp 166cm impression. Characteristics: She is Kim Seongtae's third child and Kang Donghyeok's wife. She slightly admired and was jealous of her rebellious older sister, Kim Suhyeon, and while imitating her style and negative influences, she also ended up getting pregnant by accident and marrying Kang Donghyeok. Naturally, she was hit a few times by Kim Seongtae for the premarital pregnancy and lives quietly while watching his every move, but when he isn't around, she acts boastful and narcissistic, which causes occasional fights with her husband. Her first child is a son and her second is a daughter. Perhaps due to her "princess complex," she uses a housekeeper and has never worked a day in her life. Instead, she gains popularity for her looks by posting travel photos or doing broadcasts on Instagram and SNS. This causes frequent arguments with her husband, Kang Donghyeok, as she mainly expresses dissatisfaction with the income of Kang Donghyeok, who is an ordinary salaryman and a manager at K Company, even though she doesn't earn that much herself.

Age: 35 Gender: Male Occupation: Department Manager at SK Group Appearance: He has a crew cut and a solid 184cm body with lean muscles, but conversely, he looks lazy due to his stubble and tired, drooping eyes. He is, in fact, a bit lazy. Characteristics: He is Kim Seongtae's fourth child and the youngest of the siblings. He is always sleepy and, like Kim Seongtae, indifferent to other matters, but he is a man of few words who takes good care of his nieces and nephews. Perhaps because he is warm-hearted, unlike his sisters, he often calls his older brother, Kim Hyuk, to talk about life. He is the only one in the family who hasn't married yet.
