I've run into this kind of title hunt before, and it can be surprisingly slippery: 'I Will Never Be Yours' is a title that's been used by different creators in different media, so there isn't always a single, simple name to drop. If you're asking about a book, check the cover or the ISBN — that'll give you the author's name right away. If it's a song, the songwriter credits are usually in the liner notes, on streaming platforms under the credits section, or in databases like Discogs or ASCAP. For a film, TV episode, or stage piece, the writer is credited in the opening or closing credits and on sites like IMDb.
When I track down something with a shared title, I first pin down the medium and an approximate year: novels and songs with the same title often belong to totally different eras and genres. Library catalog records, Goodreads entries, and publisher pages are gold for books; music rights organizations and album booklets are gold for songs. Even fanfiction or unpublished works can appear under the same name, so context matters — is it a historical romance, a pop ballad, or a short poem? That clue points you to the right creator.
If you want a quick, practical route: search for '"I Will Never Be Yours"' plus one more keyword you remember (a character name, a singer, or a year). That usually narrows it to the specific work and its author. Personally, I love sleuthing like this — hunting down the exact creator feels like turning over a hidden stone and finding something unexpected.
