Sincère places us right in the middle of a breakup gone nuclear. Cobalt’s narrator flees the city, crushes a cigarette, and declares Je fous tout en l'air—“I’m blowing everything up.” The song moves like a restless road trip: references to G.I. Joe, UFOs, and late-night rodeos underline how out-of-place and unanchored he feels. Over a moody beat, he grapples with total freedom that suddenly feels more frightening than thrilling, asking the one question that keeps looping in his mind: Were you ever sincere?
Beneath the rebellious energy lies raw vulnerability. The singer admits he loved “à la folie,” wrote poems that were never read, and even memorised the other person’s sad laugh. Each explosive line is paired with a quieter plea for honesty, showing that anger and heartbreak often share the same pulse. By the end, Sincère is less about escaping a city and more about escaping the doubt that lingers when love’s words and actions no longer match.
