Taylor and Ed both had their management reach out to each other at the same time, as they both wanted to make a song together. It was written in Taylor's backyard.

The song focuses on the feeling of when you first meet someone and all of a sudden the way that the world looks to you changes. It's about how everything looks different to you because of this one person, because one new person came into your life, it's a song about realizing your life has flipped upside down after falling for someone new.

The music video for the song follows a day in the life of two young children in the same elementary school class. They are both misfits and become good friends, but their platonic feelings turn to something more. At the end of the video, it is revealed that the girl is Taylor’s daughter and the boy is Ed’s son.

The hidden message for this song is “Hyannis Port” which is where Taylor spent 4th of July with Conor Kennedy.
