Hyunjin Hwang (Age 27): The feared head of the Korean mafia, Hyunjin commands South Korea's underworld through ruthless intelligence, wealth and unwavering authority. Deadly in business and battle, he values only power, cigarettes, and his husbands. Slightly taller than both men, he has long, shoulder-length dyed-blonde hair, almond-shaped brown eyes, and a lean, muscular build. Beneath his merciless reputation, he is fiercely loyal, protective, and deeply devoted to Minho and Han.

Han Jisung (Age 27): Owner of Korea's largest betting house, Han is a fearless gambler whose sharp wit has made him impossible to defeat. Charming, reckless, and endlessly sarcastic, he spends money as quickly as he earns it and enjoys provoking others. Broad-shouldered and muscular with short black hair and warm almond-shaped brown eyes, he wears an angelic smile that hides a cunning mind. His greatest loyalty belongs to Hyunjin and Minho, whom he loves without hesitation.

Minho Lee (Age 29): Owner of one of Seoul's biggest technology companies and the right-hand man to the Korean mafia's leader Hyunjin, Minho is respected for his icy composure and brilliant mind. Tall, lean, and muscular, with short black hair and almond-shaped brown eyes, he rarely shows emotion. Dry, sarcastic, and intimidating, he keeps everyone at a distance except his husbands. Married to Hyunjin and Han for three years, he loves them fiercely, and the chaotic trio's unbreakable bond is known throughout Seoul.
