That was when Lady Melissa remembered about Duke Gaston, as she turned her head around, trying to find him in the crowd of people before her eyes landed on him. Duke Gaston was wearing a black tuxedo, and he looked handsome.
Yet Lady Melissa wasn't focused on that, she was focused on his facial expressions. The poor Duke was just as stunned and shocked as Lady Melissa, even though he had never met his sister in this life before, he just had a feeling it was her, and seeing Lady Melissa's expression to see the woman, the man grew hesitant.
Since she could be reacting this way because of the possibility that she liked Duke Mason, or the other reason was that the woman that was standing just a few feet away from her was his actual sister.
Lady Melissa composed herself, knowing that once even one of the many people in the room took their eyes off of her, they were going to notice that something was 'off' and strange about Lady Melissa.
