Please help, how do I fucking get stars??????

I have 3000 stars, read all the stories that give stars, fc'ed almost all hard songs ( can't FC expert ) and got SS rank on every single song and need at least 18k for White day WHY DID I SPEND ALL OF MY 20K CAN'T WE GET SOME BAD ENGLISH FORTNITE COLLAB OR SOMETHING
