"Boy Bye" was produced by Yeti Beats, Rogét Chahayed, Carter Lang, and Kurtis McKenzie, and follows "FYS" which was released earlier this year and her debut solo album, In Pieces, released last year.

Speaking about the song, Chlöe says: “’Boy Bye’ is an anthem for anyone who needs to get rid of someone toxic and draining from their life. It’s liberating and free. That’s how it feels to finally let go of dead weight that’s been keeping you down. Instead of being sad about releasing what’s not good for me, I celebrate it.”
