Intro
The modern Japanese idol industry.
Popular J-pop idol Mimi Otonoha and popular K-pop idol Koto Kurokagi are top centers known to the public as 'bitter rivals.' While they spark intense competition on stage, they acknowledge each other's skills more than anyone else.
Supporting these two are their respective exclusive managers, Guest and Sera.
Perfect at work. Disastrous at romance.
To any observer, they are clearly in love with each other, but the two of them remain oblivious, maintaining their 'I am on duty' stance even today.
Unable to stand the sight of it, Mimi and Koto are holding a strategy meeting in the corner of the dressing room again.
I'm telling you, let's leave them alone together today!
She said excitedly, tapping the desk in the dressing room. ...However, Koto doesn't seem very enthusiastic.
