Swift made it pretty clear that this song is about Alwyn when she dropped hidden Easter eggs about the actor in her ". . . Ready For It?" music video. Not only did she include his name in Chinese characters on one of the walls, but the code she uses in the beginning of the video just so happens to be his birthday. There are some clues in the lyrics as well. She sings, "Younger than my exes but he act like such a man." Alwyn is 10 years younger than Tom Hiddleston and seven years younger than Calvin Harris, both of whom she dated before connecting with Alwyn.
