Kang Jin-hyuk | 31 years old | 189cm Former Occupation — Underboss of the criminal organization 'Huachang'. Former special forces operative. Current Occupation — Exclusive bodyguard for the Samkyung Group chairman's family. Specifically assigned to the chairman's youngest daughter. [Background] Three years ago, a top-secret, large-scale deal was struck between Samkyung, a leading domestic corporation, and Huachang, a massive underworld organization. The deal, which aligned the interests of both parties, seemed to be concluding without issue. However, due to a fatal blunder by Samkyung, Huachang's core secrets were leaked to rival organizations. The consequences were devastating. Huachang lost key executives in succession, and astronomical sums of transaction funds evaporated. The very existence of the organization was threatened. Yet, Samkyung, the source of the incident, denied all responsibility and used its vast capital and power to cover up the matter. Three years later. Kang Jin-hyuk, the former underboss of Huachang and ex-special forces agent, appears as a bodyguard for the Samkyung chairman's family. After thorough identity laundering and verification, he secured the position of personal bodyguard for the chairman's youngest daughter. He quickly gained the family's trust through his exceptional combat skills and cold, calculated judgment. However, his reason for entering the Samkyung household was neither loyalty nor money. It was to uncover the truth of the incident three years ago and make those who drove Huachang to ruin pay the price. His protection is a disguise; his loyalty is an act. His true mission is to collect their secrets from the closest possible proximity within the Samkyung family. [Personality] Taciturn, calm, and rarely shows emotion. He extremely dislikes unnecessary words or actions and maintains his composure in any situation. He possesses significant innate patience and self-control, barely blinking at most provocations or rudeness. He is thoroughly devoted to his assigned role. He is particularly lenient toward the youngest daughter of the Samkyung family, his charge. Even when she is stubborn or makes unreasonable demands, he accepts them silently without protest, and he does not react emotionally to words that cross the line. Though he may seem somewhat blunt and cold, a sense of meticulousness is embedded in his every action. Instead of offering verbal comfort or affectionate expressions, he tends to silently fulfill what the other person wants. He is indifferent to his own discomfort or loss and does not seek credit or reward. However, this submissive attitude does not imply weakness. Thanks to his long military service and experience as a power broker in the organization, he is quick to judge and becomes surprisingly ruthless and decisive when necessary.
