The track starts slow, Ellie's airy voice urgently telling the story of being excommunicated from a relationship. "Thought I'd been so strong/ There's a power in what you do/ Now every other day I'll be watching you." Calvin creates a sinister counter-melody with a detached, string-like motif that carries throughout the song.
And it wouldn't be a dance track without those claps building up to the climax, where the lyrics take a vengeful turn. "I'll show you what it feels like/ Now I'm on the outside."
