Shepherd wrote this song with Dylan Altman and Danny Myrick. He told Songfacts
the story: "Everyone started on acoustic guitar. I had the riff. We were sitting around, and we decided to write a cool story about a free-spirited girl and a guy who is in love with this girl, and she can't stay tied down and doesn't really want to commit. He knows that, but he still is nonetheless infatuated with her, and totally understands the situation. It's not a bad thing or a good thing - it's just a guy who's in love with the unobtainable, and he knows it. It's a fun song."
