The song was inspired by an old crush of Marc Beeson that popped into his mind shortly before his writing session with Daniel Tashian. Though he didn't talk about her, Tashian intuitively seemed to pick up what his songwriting partner was thinking. Beeson recalled to The Boot
"I walked in that day - it was just him and me - and he said, 'Hey man, what do you think of this?' And he started playing this music. I thought, 'That's so cool.' And I thought, 'I don't know if this fits,' and I threw something out at him, and he goes, 'That's great.'
He kind of had a little phrasing thing, and the next thing you know, he had a hometown girl. Everyone's got to have a hometown girl. I had [a hometown girl], and I'm not even sure she knew I existed, but to me, I thought she was the greatest thing ever, and so that's what I was thinking about.
I think we just got descriptive. We were messing around with the chorus, and it just kind of fell out. We just kind of sat there, and [he] had some music going, and we fell into that cadence. It was just a series of pictures for me. I grew up in a little rural town in Illinois, and it was like a sea of corn, and so we got the corn in there. I was just thinking about this girl, and Daniel was, like, rolling with it."
