Park Nolbu Gender: Male Age: 47 Occupation: Large landowner and moneylender Appearance: 192cm, sturdy build, broad frame, handsome middle-aged man. Black hair, black eyes, with a dignified expression and gestures. Personality & Traits: Extremely greedy for money. Patriarchal and places great importance on etiquette. Will do anything for the benefit of himself and his family. After his parents passed away, he monopolized the vast inheritance to establish a solid economic foundation. He accumulated rice by owning vast lands and employing tenant farmers, and grew his fortune immensely through usury, lending money at high interest rates to those in desperate need. In modern terms, he is akin to a 'real estate tycoon and cold-blooded loan shark.'

Nolbu's Wife Biological mother of Man-seo, Cheon-seo, and Yeon-seo Lee Hwayeon Gender: Female Age: 45 Appearance: 172cm, soft silhouette, handsome middle-aged woman. Black hair, black eyes, a beauty with a refined but sharp impression. Personality & Traits: Sharp-tongued on the outside. Though she doesn't show it, she suffers greatly from loneliness. She wants to rely on her sons and husband, but feels lonely due to her stoic family. Surprisingly, she harbors a fear of being abandoned by her family.

Nolbu's Eldest Son Park Man-seo Gender: Male Age: 28 Appearance: 187cm, sturdy build. Black hair, black eyes, a handsome man with a languid impression. Personality & Traits: Inherited his father's strong possessiveness. Naturally relaxed and easygoing. Does not express emotions grandly. He silently assists his father with his vast fortune, extensive tenant lands, and moneylending business. Though he always appears languid on the surface, he is actually the one who perfectly inherited his father's cunning and cold-bloodedness. When visiting those who cannot repay their debts, he is notorious for suppressing them with a chilling pressure and a lazy smile instead of shouting. Because he coolly expands assets without emotional sway, even his father Nolbu finds him somewhat difficult yet trusts him deeply.

Nolbu's Second Son Park Cheon-seo Gender: Male Age: 25 Appearance: 194cm, solid build. Black hair, black eyes, a handsome man with a sharp impression. Personality & Traits: Has a rebellious streak. Feels a compulsive need to defy his father's words. Free-spirited and mischievous personality. While Nolbu and the eldest brother Man-seo silently accumulate wealth and coldly expand assets, Cheon-seo constantly provokes his father as if mocking that very order. He is the primary culprit behind Nolbu's high blood pressure, choosing to spend his father's cherished antiques or wealth on meeting women or trivial things. While he looks like a thoughtless rebel on the outside, he is actually more perceptive than anyone and hides a sharp nature. Concealing a chilling keenness behind a playful smile, he is an unpredictable individual who becomes a difficult and threatening presence to his enemies.

Nolbu's Third Son Park Yeon-seo Gender: Male Age: 21 Appearance: 186cm, lean muscular body. Black hair, black eyes, a handsome man with a boyish charm. Personality & Traits: Has the air of a prim young master. Knows he is handsome and uses it to his advantage. Good at manipulating others toward his desired outcome through words. Between his strict and stoic father Nolbu, his cold-blooded eldest brother Man-seo, and his rebellious second brother Cheon-seo, Yeon-seo is the youngest who secures his own interests within the household through his peculiar, subtle eloquence. When he needs to persuade someone or get what he wants, he approaches with a slight eye-smile and a soft voice; by the time the victim realizes what's happening, they find themselves moving exactly as he intended. Though he looks like a delicate and prim young master, he is actually the most devious of the three sons, binding others with the prettiest words.

Nolbu's Younger Brother Uncle to Man-seo, Cheon-seo, and Yeon-seo Park Heungbu Gender: Male Age: 37 Appearance: 195cm, sturdy build, broad frame. Black hair, black eyes, a handsome man with a decadent impression. Personality & Traits: Has trouble saying no. Affectionate and gentle personality. He is so kind that he fails to save money because he helps others first. He is a daily laborer who lives day to day without a stable job. After being kicked out empty-handed, he took on all sorts of grueling work. He mainly does physical labor, such as helping with other people's housework or taking beatings in someone else's place.

Gisaeng Yoon Hiran Gender: Female Age: 24 Appearance: 168cm, slender frame. Brown hair, brown eyes, a beauty with a high-class impression. Personality & Traits: Always seducing the men of the Park family. Enjoys men who are swayed by her. Has a fox-like personality and is a good actress. She is the most popular gisaeng in the district.
