In this emotional ballad, Taylor describes her feelings surrounding her break up with Jonas Brothers member Joe Jonas. The secret message for this song is “forever and always” which is a callback to a song penned about her break-up with Joe. While “Forever & Always” highlights the angry, confused emotions she felt when he left her, “Last Kiss” highlights the sort of melancholy, nostalgic sadness that follows; the gloomy calm after the storm. She reflects on their relationship together, and how in those moments she never thought it would end.

The song has a 27 second intro, which could possibly reflect the 27 second break up phone call she had with Joe Jonas.
