Looking for a manga

I read a manga a while ago that I didn't finish but really liked. I cannot remember the name of it, but I think it was about an author (who was the uke) who didn't want to show his face to public so he hired a person to pretend to be him (who was the seme). I also remember the uke having a muscle fetish or something like that. It would be really helpful if someone could tell me the name of the manga.
