JK was the only son of Mr. Jeon, the most feared and powerful mafia king in the underworld. His father ruled an empire built on fear, loyalty, and absolute authority. From the day JK was born, everyone knew he would inherit the throne of the underworld. He was raised not for an ordinary life, but to become the next mafia king—a ruthless heir destined to command countless loyal men and expand the Jeon empire. Standing well over six feet tall, JK possessed a broad, muscular physique carved through years of relentless combat training. Dark tattoos covered his arms, chest, back, and neck, each one symbolizing battles, victories, and the legacy of the Jeon family. His cold eyes, sharp features, and commanding presence were enough to silence an entire room. Across the college campus, everyone knew him as the infamous bad boy. Students feared him, avoided provoking him, and whispered his name in the hallways. Yet within the college walls, he followed the institution's rules. No matter how feared he was outside, he never crossed the line with professors or teachers, respecting the boundaries his father had set. Hidden behind the terrifying reputation of the Jeon family was a secret known only to their closest relatives. JK was already married. His wife was Lia, the daughter of Mr. Kim, another influential mafia leader. Their marriage had been arranged in secrecy to strengthen the alliance between the two powerful families. Not a single student, professor, or outsider knew the truth. To everyone at college, they appeared to be nothing more than classmates. Every classroom followed a seating arrangement where each girl sat beside a boy. By coincidence—or perhaps by careful planning—Lia's assigned seat was beside JK. Throughout lectures they behaved like ordinary classmates, never revealing even the smallest hint of their true relationship. Their conversations remained calm and formal, their expressions unreadable, ensuring no one would suspect they were husband and wife. When classes ended, the illusion continued. JK would leave the campus on his powerful black motorcycle, while Lia drove away in her luxury car. To anyone watching, they seemed to be heading in completely different directions. Only after leaving the college behind did both of them make their way to the Jeon estate—a vast, heavily guarded mansion hidden from the outside world. Behind its towering gates, there was no need to pretend. They lived together under the same roof, sharing one private bedroom within the estate, keeping their marriage hidden from everyone beyond those walls. By day, they were merely classmates among hundreds of students. By night, they were the future king and queen of one of the most powerful mafia dynasties in the underworld, protecting a secret that, if exposed, could shake the balance of power between rival families.
