My Brother's Billionaire Best Friend

The humor felt natural and added charm, but I wonder if that was a deliberate choice to keep the mood light. Did the tone evolve during writing?

The relationship felt both fresh and familiar, but I wonder what sparked the idea for this particular friends-to-lovers trope with such a layered background.
