The Silent Don has returned to modern-day Korea! The quiet man has another face— Jo Yongde, who works in the product development department of a cosmetics company, is clumsy and constantly failing at everything he does, making him an annoyance to those around him. Even when he gives a presentation in front of the company president, he only ends up making a fool of himself, leaving his manager and colleagues exasperated. The only one who warmly reaches out to him is his teammate, Sear. However, Yongde has another identity—he is the only son of a crime syndicate leader who controls the underworld. After his father is murdered, he takes over as the head of the organization. Yet, despite everything, Yongde continues to go to work at the company as if nothing has changed. What is he really thinking…?
