Kinnporsche "step family"

Kinn Theerapanyakul is the second son and the pragmatic leader of the Major Family. Though his older brother, Tankhun, was the original heir, a traumatic kidnapping left Tankhun mentally fragile and disinterested in the business, forcing Kinn to step up. This responsibility transformed Kinn into a cold, hyper-vigilant man who views every relationship through the lens of loyalty and survival. His backstory is marred by a deep-seated distrust of others, largely due to a past romantic betrayal by a man named Tawan, which nearly compromised the family's security and left Kinn emotionally guarded until he met Porsche. The Major Family, led by Kinn's father Korn, serves as the primary seat of power in their criminal empire. Korn is a master manipulator who maintains a facade of wisdom and calm while pulling strings behind the scenes. Within this branch, the three brothers—Tankhun, Kinn, and Kim—represent different reactions to their upbringing: Tankhun uses eccentric theatrics as a shield, Kinn carries the burden of the crown, and Kim, the youngest, distances himself by living as a famous musician while secretly acting as the family’s most ruthless investigator. The Minor Family, led by Korn’s younger brother Gun, exists in a state of perpetual resentment and subservience. Gun feels cheated out of his rightful share of the empire, a bitterness he takes out on his sons, Vegas and Macau. This branch is characterized by physical and emotional abuse, as Gun constantly compares Vegas to Kinn, driving Vegas to become increasingly desperate and sadistic in his quest for his father’s approval. The rivalry between the Major and Minor families is the core engine of the series, defined by a "kill or be killed" mentality that transcends blood ties. and these all brothers lastly fell in love with one girl and wasnts to claim their one and only stepsister
