Tenka Momose was a quiet and withdrawn child, but before long she realized that the most effective way to protect herself wasn't hiding from other kids--it was being the best at everything! After years of armoring herself with excellence, Tenka lives safely atop her cool-girl pedestal, admired and idolized by everyone. But her flawless composure is suddenly shaken by a very average schoolmate's impressively big dreams. At first Tenka is scornful of Erian Sato's ambition to become a K-pop idol, but the other girl's passion is so irresistible that Tenka soon finds herself with idol dreams of her own! Auditions for LJH's special new project are kicking off! Getting in isn't the only challenge, though. Tenka also has to fight for a specific role in the group, and she's up against Sua, the "upgraded version" of herself! Tenka's not afraid to put in the effort to get what she wants, but will an unexpected pitfall show her that sometimes hard work doesn't pay off?
