The present structure employs the high school setting where the seven members of the cast portray students with distinct characters. The cast is diverse, including a comedian, a former athlete, and a K-pop celebrity. In each episode, a pair of guests (or occasionally, a group) are introduced as new transfer students. Just like in typical high schools, all class members are assumed to be the same age, disregarding their real age, experience, and previous acquaintance with each other, and they engage in a sharp, instigating yet amusing conversation. Their performance isn't limited to the written script: their excellent spontaneous dances and off-the-cuff sketches that blur the line between reality and fiction are downright comedic.
