• The song was written and produced together with Jack Antonoff from
Fun.
• Taylor explained: "This song is about the fragility and kind of breakable nature of some relationships.
This was a relationship where it was kind of living day-to-day, wondering where it was going, if it was gonna go
anywhere, if it was gonna end the next day. It was a relationship where you never feel like you're standing on
solid ground."
"And that kind of a feeling brings on excitement, but also extreme anxiety, and kind of a frantic feeling of
wondering. Endless questions. And this song sounds exactly like that frantic feeling of anxiety and questioning,
but it stresses that, even if a relationship is breakable and fragile and full of anxiety, it doesn't
mean that it isn't worthwhile, exciting, beautiful and all the things that we look for."
• It has been speculated that the song is about Swift's brief fling with
One Direction's
Harry Styles.
While the duo were rumored to be together, Taylor and Harry were both seen wearing identical
silver necklaces each with a paper plane shaped symbol, which is referenced in the song.
