[Intro] (Gentle, dark piano chords, subtle cello pad) [Verse 1] (Intimate, fragile female vocals, solo piano) I know I can't take one more step towards you 'Cause all that's waiting there is regret And you might think you're still the one who owns me But I'm not the ghost you left behind [Pre-Chorus] (Strings softly enter, subtle tension building) And who do you think you are? Running round leaving scars Collecting dreams just to break them apart [Chorus] (Expressive vocals, full piano, dramatic cello swell) You're gonna catch a cold from the ice inside your soul Don't come back for me, don't come back at all Who do you think you are? Stealing light from the dark You won't get another piece of my heart [Verse 2] (Pulsing low piano bass, steady rhythmic pace) It took so long to put myself together To build these walls and lock the door Now you come knocking like you never left here Expecting me to fall once more [Pre-Chorus] (Strings rising, drums slowly building) And who do you think you are? Running round leaving scars Collecting dreams just to break them apart [Chorus] (Soaring belt, powerful lead vocals, full string section) You're gonna catch a cold from the ice inside your soul Don't come back for me, don't come back at all Who do you think you are? Stealing light from the dark You won't get another piece of my heart [Bridge] (Stripped back piano, raw emotional voice rising to high pitch) And it took so long to feel alive again... I won't let you drag me under... No, not again! [Chorus] (Maximum emotional energy, cinematic drums, soaring vocals) You're gonna catch a cold from the ice inside your soul Don't come back for me, don't come back at all Who do you think you are? Stealing light from the dark You won't get another piece of my heart [Outro] (Slow piano notes, gentle breathy voice) Don't come back for me... Who do you think you are? (Fade out)
