Are you looking for an animö?

So I'm looking for an anime because I started but then stopped looking because of my broken laptop. It was about a boy who could sing really well but because (I think) he had a scar or something similar. He couldn't be an idol on his face. He wears a fox mask and makes music that he uploads to something like yt, spotify or something. And I can still remember that he is the idol for the playback voice and in one episode the power goes out and he sings in the dark so that nobody notices. I think he is under contract with someone and has to keep secret that he sings for the idol and joa 😅 Please help me, I thought he was really cool.
