Méfiez-vous de l'homme qui dort

The humor feels so natural and charming, but I wondered if that was a conscious choice or just how the characters developed. Did the tone evolve during writing?

I found myself rooting for him, especially when he tries to hide his true self. Am I the only one who saw parts of themselves in his struggles?

His quirks made him so memorable, but I wonder if those traits were based on real experiences or just a fun character detail to explore.
