"Happiness" also seems to reference Gatsby, Daisy, and the infamous green light.
Swift said it's about "the realization that maybe the only path to healing is to wish happiness on the one who took it away from you."
Also in verse two, Swift sings pointedly, "I hope she'll be a beautiful fool / Who takes my spot next to you."
Finally, Swift makes Gatsby's influence clear by using the book's most famous symbol.
In "The Great Gatsby," the green light at the end of Daisy's dock represents Gatsby's undying love (or obsession, depending on how you look at it).
