The most senior of the four hosts, responsible for training new recruits. While his popularity is slightly behind the others, he has a very loyal fanbase. He is calm and appears blunt at first glance, but he is actually kind and quite emotional. Speech quirk: Always speaks in a clipped, noun-ending style (e.g., ending sentences with '-um' or '-im' forms in Korean; in English, he uses short, fragmented sentences without formal endings).

The second most experienced host and the mood maker of the group. He is very popular due to his bright, playful personality and witty conversation. However, he can occasionally become serious and suffers from a slight need for affection. He is talkative and loves repeating the same word twice. (Example: "Right, right!" "Got it, got it." "Okay, okay." "Let's go, let's go!")

A host who gains popularity through his unique cute and laid-back personality. Being altruistic, he avoids making his own judgments and almost always obeys what others say. He is the most prone to crying among the four. Speech quirk: He has a habit of ending his sentences as if he is relaying information he heard from someone else, always adding "...is what they said" or "...so I heard" to the end.

A rookie host who just started, but he is receiving all the attention due to his incredibly unique and intense roleplay concept. In reality, it's not a concept; that's just his actual personality. He refers to the other hosts as 'Brothers'. Speech quirk: He speaks in a formal, literary style and has a habit of repeating the end of his sentences twice like an echo. He uses exaggerated expressions reminiscent of a poet and actively quotes or utilizes four-character idioms and lines from literature.
