She understood that Fuhua had so many questions to ask his friend. But it would be difficult for him to talk in her presence. Hence she decided to give them some privacy.
Since they are already outside, she asked them to roam around for some more time. Since it would be impolite to tell them to leave when Wang Deming had asked them to go to their manor, she even invited Fuhua to come back to the manor after spending some time with his friend. This way, she showed that she had no problem with having a guest at her home.
Fuhua had liked her suggestion because he too was embarrassed to face her immediately and it would be very awkward to talk to Wang Deming freely when he knew that Jiang Xiurong was still under the same roof when they would talk about her.
Yet he did not nod his head but he looked at Wang Deming eagerly as if a dog was seeking the permission from his owner to go out by wagging its tail furiously.
