Yug yes I do feel sorry for him - but he is partly to blame - he has always been around anjali - causing misunderstandings.
He never intentionally tried to hurt Anjali & Kavya's marriage. He only happned to be at the wrong place at the wrong time. Unlike Pammi, he didn't do anything knowingly to break up K & A. Now if Kavya misunderstand's Yug's friendship with Anjali, then that is Kavya's problem, not Yug.
In my opinion, Yug should not be blamed, even partly. That's just what I think.
