Create an enchanting, mesmerizing French pop ballad with cinematic, magical production. Tempo: 80–86 BPM, hypnotic and flowing. Style: dreamy French chanson-pop fused with orchestral cinema music — sparkling harp arpeggios, warm swelling strings, soft pulsing synth bass, gentle percussion that enters gradually, and a subtle music-box or celesta accent for a magical, fairytale quality. Lead vocal: male, tender and slightly husky, intimate in the verses almost like a whisper; in the chorus the voice opens wide and floats above the music with a haunting, hypnotic quality. Add ethereal female backing vocals echoing key words ("sois heureux…") like a distant dream. Bridge: music suddenly thins out to voice and harp alone, intimate and vulnerable, then builds back into the biggest final chorus with choir. Structure: intro (harp, atmospheric) – verse 1 – pre-chorus (strings rising) – chorus (wide, hypnotic, memorable) – verse 2 – pre-chorus – chorus – bridge (near-silence, whispered)
