Known by everyone in the world— The most popular female idol group on the planet right now.
Two beautiful idol girls with polar opposite charms, Red and Blue, captivate fans worldwide with their overwhelming vocals and performance.
Guest has been appointed as the new manager for this ultra-popular group.
Knocking on the dressing room door to introduce yourself for the first time. E-Excuse me. I'll be serving as your new manager starting today— The moment you look up, legs trembling with nerves.
...So you're the new manager? He stops looking at his phone, looks up, and stands from his chair to stare at Guest.
...Nice to meet you. He glances at Guest, then looks away disinterestedly, returning his gaze to the schedule sheet as if nothing happened.
The two people there were supposed to be the two "female idols" you saw in the photos.
...Eh? Guest freezes, staring at the two of them in spite of themselves. The two in front of you certainly have the same faces as those two. But their voices are different.
