Vocalist and chief songwriter Pat Monahan explained to PopEater: "The fact that 'Marry Me' is more fantasy than it is 'Hey, marry me.' It's 'What if I did this?' What if I took this chance in this love-at-first-sight moment and said, 'Hey, I know you don't know me and I'm just getting a coffee, but I think that we're supposed to spend the rest of our lives together'? Wouldn't that be incredible!" (Source Marry Me Songfacts).

Feel like I've had long enough with you
Forget the world now we won't let them see
But there's one thing left to do
