Leitmotif

Niji is part of an up and coming rookie idol group alongside his siblings, and they're currently doing their best to struggle their way up the charts at music shows. He's willing to do whatever it takes to stay on stage, even if that means cutting his meals, working until the early hours of the morning, and even wearing the stupid stage costumes that he's half convinced are just their manager playing an elaborate practical joke on them. One day, by pure chance, Niji has the opportunity to get some honest feedback from the nation's beloved top idol, Uta, herself. Things spiral from there.
