Forthright and impetuous Eripiyo is the number one stan for Maina, a sidelined member of the underground idol group Cham Jam. But despite her heartfelt admiration, Maina barely seems to be able to look Eripiyo in the eye, let alone acknowledge her devotion. Up until now, Eripiyo has spent a fortune on CDs, merch, and fan meetings -- but when an injury puts her out of commission, she despairs to realize she can no longer afford the costs of idol fandom. But her sudden absence doesn't go unnoticed, leaving Maina to wonder: has she been taking her best fan's devotion for granted all this time? Has Eripiyo found a new favorite among the Cham Jam members? What can she do to win Eripiyo's heart back to her?
