After the song's release, it drew much attention in the LGBT community.^[3][8] In a 2017 interview with Billboard, MAX stated that "It's not our song anymore. It's everybody's song. Everybody is able to add whatever they want to it, what it is to them, and in that way, it becomes so much less — it's not about us anymore. It's not about even the artist or the writer or the singer, it's about what it can stand for for people."^[3]
