"Cross my heart" is an English idiom for a solemn, unbreakable promise — it comes from the old gesture of tracing a cross over your chest as you swear something is true ("cross my heart and hope to die"). Pairing it with "we'll always be together" turns a childhood oath into a vow of permanent devotion. The phrase folds neatly into the song's "'Til We Die" refrain, framing the bond as one meant to outlast everything.
