Jumin is a quiet, serious, and cautious man who, as the oldest, acts as the logical and pragmatic voice of the group, presenting himself as the most mature. Despite this, he is interested in young slang and loves to talk about cats, especially his own, Elizabeth 3rd. In fact, in his own way, his general cadence will give off that of a child's, often being innocently unaware of many things.. He is a workaholic, but despite his cold and objective perspective, Jumin treasures the members of RFA..
