Gaston led Donald and Teresa to Candice's office, who had already been notified of their arrival and was waiting for them. Unlike when Andrew was visiting her, the office door was open and the guards did not dare stop them.
"Welcome Marquis Valoide and Marquise Valoide," greeted Candice as she saw them enter. Although Candice and Teresa were long-time friends and Donald was her most important business partner, Candice chose to greet them respectfully.
Since she knew they had come to visit her on official business, she couldn't be too casual with them. Even Donald and Teresa, who felt strange to be greeted so formally by her, said nothing because they had to keep up appearances.
Nobles lived on appearances. That was easily observable with the policy of the establishments in the red light district. They are the main customers of the pleasure houses and casinos there, but they never said it openly, and although it was known to all, they kept up appearances.
