Following the release, JYP Entertainment producer J.Y. Park shared via Instagram that "The Best Thing I Ever Did" is his 588th self-composed song. He stated, "This is the 588th song that I wrote/composed. So in order to include some new vibe to my song, I just made the track and the hook and sent it to other writers and had them fill in the other melodies. What do you think? :)"
