Grimoire literally translates to "spellbook" or "book of magic spells". It's a fascinating and somewhat archaic word that evokes images of ancient secrets and forgotten knowledge.
In this song, Grégoire uses it metaphorically when he sings, "J'inscrirais dans ma mémoire / Comme au fond d'un vieux grimoire" (I would inscribe in my memory / Like deep within an old grimoire). He's comparing his memory of a past love to a precious, secret book where he keeps cherished moments, making the word feel both intimate and magical.
“Coup Du Sort” is Grégoire’s warm, nostalgic way of saying that a breakup does not have to erase the love that came before it. The song’s narrator accepts that time, routine, and a touch of bad luck have pushed the couple apart, yet he refuses to let their story fade. Instead, he stores “des petits bouts de nous comme un trésor”—tiny fragments of shared laughter, looks, and late-night conversations—in an imaginary treasure chest. Far from being bitter, he celebrates those memories as magical charms that can still make him stronger and kinder.
Think of it as a loving postcard to the past: the fires of passion may have gone out, but the glowing embers remain tucked safely in his “old spellbook.” By choosing to keep only the best parts, he turns heartbreak into a gentle lesson on gratitude, resilience, and the sweet aftertaste of a love that once was. “Coup Du Sort” invites listeners to hum along, smile at their own souvenirs, and trust that even endings can sparkle with tenderness.
