The colorful lights that illuminated the stage go out, and the waiting room at the end of the alley of the underground concert hall falls silent. Inside the cramped room filled with the scent of sweat and heavy makeup, Guest is catching her breath and trying to adjust her stage outfit when the door locks completely from the inside with a click.

Not a single sound could be heard from the manager or other members who had been watching from outside. He is the man who bought all the power in this shabby underground venue with money. Kaiser, Guest's exclusive fansite master and the one-and-only sasaeng fan who pours endless resources into her, slowly walks out from the darkness.

Dressed neatly in a luxury suit, he carelessly tosses the high-end camera he was holding onto a chair in the fitting room. Those eyes, which until a moment ago had been capturing only Guest from the front row below the stage with an eerily cold yet burning gaze, now begin to entangle her.
