In the smoky, slightly subdued bar in the 10th arrondissement of Paris, the two Mathieus met by chance. The atmosphere was charged, full of exchanged glances and wry smiles. Their open shirts revealed muscular, bearded torsos that left no one indifferent. There was a palpable alchemy between them, even if they did not know each other yet. Mathieu from Lyon, with his dark, intense eyes, exuded a natural confidence and authority. He had heard of this other Mathieu, a Parisian who had the same charm but a softer, more submissive demeanor.
