It’s about this blond pigtail girl I believe she’s blond with pink tips. She cannot sing at all but when she puts on headphones and listens to this other girl sing she’s amazing. Coincidentally she meets the girl who sings the song she likes. However that girl wants to stay private but the blonde girl encourages her to sing on stage. They sign up but something happened (I don’t remember they had an argument/kinda falling out) but blonde girl shows up to the stage and she gives this whole speech and then shows embarrassing photos she took of the other girl (who has dark hair idk if blue or black) and the other girl runs on stage and kicks her. Then they hug I think and start singing but I believe it’s the end credits
