It was released by Virgin EMI Records on 29 March 2019 as the second single from the band's eleventh studio album, Spectrum.
The song was written by Ed Sheeran, Fred Again, Steve Mac and Wayne Hector.
The music video was directed by Lochlainn "Locky" McKenna and was filmed in Dublin, Ireland in two locations.
The music video depicts a teenage romance blossoming in 1993, and they become estranged after the boy ignores her after a school performance, but they soon get back together.
That same girl is shown in the recording studio where the band is singing the song, all grown up.
