In this vulnerable track, Swift sings about trying to self-sabotage a relationship and, in turn, asking for forgiveness for her past mistakes. "It's all me in my head," she says, taking the blame for starting the fight. The song also has another reference to the colour blue, though this time it's because she "made" him blue. "Afterglow" is a beautiful track about true love and shows just how much Swift has grown and matured over the years.
