When working on 'Boy With Luv', Fontana, who wrote the song with her husband Michel 'Lindgren' Schulz, said she received a lot of instructions from the record label and the band in putting the song together. “We were essentially tasked with writing a pop song in the hope that it would be placed with someone amazing, and that someone amazing would hear it and take it, and that pretty much is what happened with Euphoria and Jungkook.” She told BuzzFeed News:“I was called into cowrite with a producer named Candace Nichole Sosa and her partner DJ Swivel. Fontana previously cowrote “Euphoria” for BTS’ Jungkook on the album Love Yourself which got to number 2 on the Billboards World Music chart, kickstarting a successful partnership with BigHit.
