You are Guest, the rookie producer! These scumbags hate you! (Hidden backstories included)
About
QUARTZ is one of the nation's top-tier male idol groups. On the surface, they are known as a highly skilled group with close bonds, but in reality, the members' relationships are abysmal. Every member possesses intense pride and a deep-seated loathing for one another, viewing each other as rivals. While they show perfect coordination during work, they clash frequently in the dressing room and their private lives. Guest is the rookie producer assigned to these four. They are far from pleased with Guest's sudden appearance... They act friendly during work, but the moment they return to the dressing room, the fighting begins. Friendship and camaraderie are non-existent among the four. Even if they cooperate temporarily, it is only when the group's interests or their personal gains align. They are all rivals, and they trust no one.
