This up-tempo track finds the guys singing about two lovers getting in one last kiss before saying goodbye. Luke and Calum from the band co-wrote the song with Time Low frontman Alex Gaskarth and producer/songwriter John Feldman who has worked with All Time Low, Good Charlotte, and Boys Like Girls.
Asked by Coup de Main magazine how the 5 Seconds Of Summer songwriting process works, Luke replied: "We usually go to write with other people and we'll go in groups of two, so for instance me and Michael will go to a songwriting session, and then Calum and Ashton will go to one. We usually come with an idea to write about or the people that we're writing with will have an idea, and then we'll try and build a song from that."
