Looking for an R/S fic where Sirius has admitted to James that he fancies boys, but will not say if there is someone in particular. One day Sirius, James and Remus are in the library and Remus gets up to locate a book. James is able to figure out by the look on Sirius' face as he watches Remus walk away that Sirius fancies Remus. I hope I explained that properly-- it was written so well in the fic but I can't remember which one or who wrote it.
