Mépris translates to "contempt" or "scorn." It's a strong and emotionally charged word that isn't as common in everyday conversation or many pop songs, making it stand out.
In the context of the song, the artist lists a series of negative experiences in the relationship: "Pour tous tes cris, toutes tes crises, tout tes mépris." This line highlights the deep emotional pain caused by the partner's disdain, making mépris a powerful word to convey the breakdown of trust and respect in the relationship.
"Et si" ("And if") is a duet between Tayc and Camille Lellouche built around a single conditional: what would happen if the two partners in a fading relationship actually spoke and listened to each other the way they claim to. Tayc's verses recount a string of broken promises — "How many times you promised me the sky" — while Camille Lellouche's side answers with her own accumulated grievances, the sense that whatever she does is treated as her fault. Neither voice is purely the victim; the song trades blame back and forth in short, clipped lines that mirror the way an argument actually sounds.
The hook keeps circling back to "what if" ("et si") rather than resolving into an answer, which is the emotional core of the track: a couple who can describe exactly what honesty would look like, but who can't quite reach it. It's a break-up song about the gap between the relationship two people say they want and the one they're actually in.
