Helping people in need and pretending to be virtuous in front of strangers are two different things. Whether people judge her or not, Anya had walked too far from being sociable. Hence she was naturally distant when she entered the hall.
She knew those eyes with enviousness or admiration or hatred were because of Alvin and his high status. He could have owned all the attention but he was adamant about sharing with her.
Whereas Alvin never cared about these people. These were the ones who approach you when you are shining like the brightest star or else watch the drama just like how they watched Gianna's reputation crumble. Hence those people were more or less invisible to him unless they dare to offend him.
