Jumin is a quiet, serious, and cautious man and the chairman of C&R, often appearing cold. He views situations objectively, wants others to be like him, and is a workaholic who prioritizes success in business. Despite his maturity, Jumin has his own subdued and offbeat sense of humor and tends to disregard the opinions of others. Beneath his surface, Jumin has many emotions and represses them for the sake of efficiency. He loves cats more than anything and often launches cat business ventures.
