[Verse 1 - Female] I saw you standing by the window, gold light in your hair Something in the way you smiled made the whole room disappear My pulse was thunder in my chest, I couldn't look away Like every song I'd never written suddenly knew what to say [Verse 2 - Male] You caught me staring cross the room, and I swear time stood still Your eyes were asking questions that my heart was born to fill I crossed that floor like gravity was pulling me to you Now I'm falling and I'm flying, and I don't know what to do [Pre-Chorus - Both] Every nerve is electric, every breath is a spark We're two souls colliding in the beautiful dark [Chorus - Both] We're hearts on fire, burning brighter than the stars above Hearts on fire, this is the kind of all-consuming love That rewrites constellations, that stops the world from spinning Hearts on fire, and this is just the beginning Just the beginning [Verse 3 - Female] Your fingers traced my collarbone beneath the city glow You whispered promises like secrets only we could know The night tastes like forever when your lips are close to mine I'm memorizing every moment, freezing every line [Verse 4 - Male] I've been half-alive until you set my world ablaze Now I'm wide awake and reckless, counting down the days Till I can hold you in the morning, tangled in the sheets You're the answer to the question my heart kept on repeat [Pre-Chorus - Both] Every touch is a wildfire, every kiss leaves a mark We're two flames together lighting up the dark [Chorus - Both] We're hearts on fire, burning brighter than the stars above Hearts on fire, this is the kind of all-consuming love That rewrites constellations, that stops the world from spinning Hearts on fire, and this is just the beginning Just the beginning [Bridge - Female, then Male, then Both] (Female) When the world gets cold and heavy (Male) I'll be the warmth you need (Female) When you're lost and barely steady (Male) I'm the compass, I'm the creed (Both) We're unbreakable, undeniable Written in the stars and irreplaceable [Final Chorus - Both] We're hearts on fire, burning brighter than the stars above Hearts on fire, this is the kind of once-in-a-lifetime love That breaks through every barrier, that keeps the darkness from winning Hearts on fire, and this is our beginning Our forever beginning [Outro - Both, softer] Hearts on fire... (hearts on fire) This love will never tire Hearts on fire... (hearts on fire) You're my one desire
