Alwyn is listed as a cowriter on this song under his pseudonym, William Bowery, and it contains some distinct references to their relationship.
"I spy with my little tired eye, tiny as a firefly, a pebble that we picked up last July," Swift sings at one point. "Down deep inside your pocket, we almost forgot it. Does it ever miss Wicklow sometimes?"
Wicklow is a county in Ireland, not far from Belfast, where Alwyn filmed "Conversations With Friends" in 2021. Swift paid him a visit in 2021, per the BBC, stopping by a bar to meet Alwyn and thrilling locals in the process. While the documented Belfast visit took place in September, not July, it's possible that Swift paid a more covert visit to Wicklow at some point.
