When it comes to idol group Cham Jam, Eripiyo is the oldest - and perhaps only - fan of Maina Ichii. Through thick and thin, the dead heat of summer, torrential rain, and freezing snow, Eripiyo has been there to show her love for Maina. But when Maina gets injured during a concert, her determination to push through for the sake of her group both inspires and worries Eripiyo.

A chance encounter between Maina and another fan results in a new realization that she needs to speak up more for herself. But maintaining the fine balance of their private lives and idol personas is harder than it seems...
