A girl group whose overall concept is wearing different types of masks, never truly revealing their faces to symbolize how the industry (and world in general) relies too much on physical appearance as it relates to self-worth.
Alternatively, the only other group in their company, a boy group, has the complete opposite concept, playing into every fantasy that k-pop itself likes to maintain.
Their storyline concepts mirror each other, Nightmares and Daydreams, reality and fantasy.
