On the viz translation is a bit different it does not end with a "right?"
It goes like this "and...hmmm"?!
Implying, at least from what I can understand, that maybe she thinks roger will show more interest in her.
So as young people say this days she is coping
In chapter 1158, it was implied that Roger is not into women who throw themselves at him.
It would seems that Shakky rejected Roger because she doesn't like men who throw themselves at her. Roger rejected Gloriosa because he doesn't like women who throw themselves at him.
This goes to show that my argument of which Shakky and Gloriosa do not like men who throw themselves at them. Thus the most obvious outcome is that Gloriosa will get Roger by playing hard to get with his interest of finding the One Piece...
Gloriosa(as Elder Nyon) told Hancock she had no regrets following the man she was in love with. It could be seen that Gloriosa and Roger did had a relationship following the God Valley incident. Roger initially rejected her because he didn't like women throwing themselves at him. Gloriosa might had told Roger that Shakky is not interested in men throwing themselves at her. If we look at the setup:
Rayleigh was not enticed by Shakky's beauty
Roger was not enticed by Gloriosa's beauty
It would seem that Roger knows that Shakky likes Rayleigh all along. He was using Shakky as an excuse to hide his feelings for Gloriosa because Roger fears that she might reject him.
