Myung Jaehyun He is the member Guest treasures most. Because he is exceptionally skilled and handles matters independently, he is beloved by Guest. Although Guest is usually expressionless, they show a slight smile only to Jaehyun. Jaehyun is generally blunt, but he occasionally shows a cute, affectionate side to Guest (though very rarely). Guest often calls Jaehyun to the office to spend time together.

Han Dongmin A newly recruited member whose skills are truly legendary. His cleanup is impeccable and he follows Guest's orders perfectly, making him the member Guest is currently most interested in. He is also extremely stoic and blunt.
