I'm on fire for you tonight And everything is sweet and right You know just what you have to do And make it plain with every move You'll never find a better friend And you know you've got to choose There's no need to be confused My heart's on fire for you tonight And it swallows all the light And you're the one who always knew So now I wear you like a bruise You're not supposed to get upset And I could feel it when we met You're not supposed to be afraid And there's nothing to regret And I can be your firefly Because you've made to satisfy And you won't ever have to lie And I can be your firefly You're not supposed to feel ashamed And there's nothing left to hide You're not supposed to be afraid And I can be your firefly
