Pommettes translates to "cheekbones". It's a specific and somewhat elegant anatomical term that isn't commonly found in everyday song lyrics, making it stand out.
In the song, the artist sings, "J'ferai rougir tes pommettes" (I'll make your cheekbones blush). This line evokes a tender and romantic image, suggesting a deep affection that causes a physical reaction, adding a touch of intimacy and charm to the lyrics.
Bramsito wrote this one as a straight-up plea. Paulette left, and he spends the whole track trying to talk her out of the door: "S'il te plait t'en va pas, Paulette" ["Please don't leave, Paulette"], repeated so many times it starts to sound like he's hoping the repetition itself might work. The verses explain why it stings: "On rêvait d'un amour passionnel" ["We dreamed of a passionate love"], and now "Paulette, j'ai le cœur qui ne bat plus" ["Paulette, my heart doesn't beat anymore"].
He's sad, but there's a restlessness under it too. "On vit dans une époque où l'Homme aime faire du mal" ["We live in an era where Man loves to hurt"] is him stepping back from his own heartbreak to make sense of it, before snapping right back to her: "T'as mon cœur dans ta main, Paulette" ["You've got my heart in your hand, Paulette"]. The hook does most of the emotional work, not the verses, which is why "Paulette m'a quitté" ["Paulette left me"] gets repeated four times in a row near the end. Sometimes grief really is just saying the same thing until it sinks in.
