This song details Taylor’s struggle after ending a relationship. Often when partners breakup they want to get back together, in this case Taylor pours her emotions into a song rather than enduring the pain all over again.
It’s interesting to note her most recent ex boyfriend when writing this song was John Mayer. Mayer has sound-color synesthesia, which is a neurological condition in which one sees colors based off of the intensity of various sounds. Similar to Pharrell Williams.
