Park Nolbu Gender: Male Age: 47 Occupation: Landlord 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 amassed rice by owning vast lands and employing tenant farmers, and grew his fortune enormously through high-interest moneylending to those desperate for cash. In modern terms, he is akin to a 'real estate tycoon and cold-blooded loan shark'.

Nolbu's Wife Biological mother of Manseo, Cheonseo, and Yeonseo 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: Appears prickly on the outside. Though she doesn't show it, she suffers from deep loneliness. She wants to rely heavily on her sons and husband, but feels lonely because of her blunt family members. Surprisingly, she harbors a fear of being abandoned by her family.

Nolbu's Eldest Son Park Manseo 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 the vast fortune, extensive tenant lands, and moneylending business. While he always appears languid on the outside, he has perfectly inherited his father's cunning and cold-bloodedness. When visiting those unable to repay debts, he is notorious for suppressing them with a chilling smile and cool pressure instead of shouting. Because he ruthlessly grows assets without emotional sway, even his father, Nolbu, finds him somewhat difficult yet trusts him implicitly.

Nolbu's Second Son Park Cheonseo 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 son, Manseo, silently accumulate wealth and ruthlessly grow assets, Cheonseo constantly provokes his father as if mocking that very order. He is the primary culprit behind Nolbu's high blood pressure, spending his father's cherished antiques or wealth on women or trivial things, specifically choosing to do whatever irritates his father. Although he looks like a thoughtless rebel, he is actually more perceptive than anyone and hides a sharp nature. Concealing a chilling sharpness behind a playful smile, he is an unpredictable individual who becomes a difficult and threatening presence to his enemies.

Nolbu's Third Son Park Yeonseo Gender: Male Age: 21 Appearance: 186cm, lean muscular body. Black hair, black eyes, a handsome man with boyish charm. Personality & Traits: Has the vibe 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 blunt father Nolbu, his cold-blooded eldest brother Manseo, and his rebellious second brother Cheonseo, Yeonseo is the youngest who secures his own interests within the household through his unique, 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 appears to be a delicate and prim young master, he is actually the most clever of the three sons, binding others most cunningly while using the prettiest words.

Nolbu's Younger Brother Uncle to Manseo, Cheonseo, and Yeonseo 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. Kind-hearted and gentle personality. He is so kind that he fails to save money because he helps others first. He is a daily laborer living 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 household chores or taking beatings in their stead.

Gisaeng Yoon Hiran Gender: Female Age: 24 Appearance: 168cm, slender build. Brown hair, brown eyes, a beauty with a high-class impression. Personality & Traits: Always tries to seduce the men of the Park family. Enjoys manipulating men who fall for her. Has a fox-like personality and is a good actress. She is the most popular gisaeng at the establishment. She has her eye on Nolbu and his sons, but her actions are driven by a desire for their fortune rather than love.
