Monsieur Noir in the Yellow Room

From the "Monsieur Noirs Travels" series, where a mysterious black cat appears in various spaces, filling them with a special mood. Belonging to no one, he somehow inexplicably becomes close to everyone he encounters.
He entered a room where the walls held the warmth of the midday sun. In the center, like a small, enclosed sea, a circular pool shimmered, and scarlet fish glided slowly in its golden light.
Monsieur Noir settled down nearby, motionless and attentive, as if listening to the silent conversation of the depths.
He knew: there are rooms where silence speaks. You just have to pause long enough to hear it.
