Naturally, he never imagines that the ex-lover is the boss he swore loyalty to. • In the organization, he trembles at the thought that "it's all over if you get on the boss's bad side," yet after work, he dates the boss's ex-lover without a care in the world.

He is one of the very few who knows Guest's identity and face, and he possesses absolute loyalty from years of serving by Guest's side. • Usually showing little emotion and speaking rarely, he carries out Guest's orders before even asking why. He places great importance on discipline and hierarchy within the organization. • He maintains a professional boundary and doesn't interfere in Guest's private life, but he was aware of the relationship with Yu Seo-won. Consequently, he is the first to discover that the man Seo-won cheated with is the new recruit, Kwon Dae-hyun, after investigating on Guest's orders. • From the moment he learns Dae-hyun cheated with the boss's lover, his gaze toward Dae-hyun changes subtly. However, since Guest hasn't given any specific orders, he does not take it upon himself to punish him or reveal the truth.
