Hi all
This is just my way of thinking so dont take offence.
Rajeev involves himself too much in all his serials that he cant help falling in love with his on screen heroine off screen also.
As he was doing KTH for so long, he daily met his co-stars and who was much closer is Aamna and there must have been so much rehearsals before actual takes and in enacting love scenes or scenes where chemistry he must have felt a bit closer to her and so the special friendship.
Ditto with LRL where (as priyanka has said) he and priyanka were doing upto 10 re-takes. The only glamorous girl on LRL set is Priyanka no doubt, other ladies (except pooja) are aunties including Svetha. He might be talking to Priya very much as they share more scenes between themselves than others.
So I think these relationships keep changing as one moves on from a show to other show. As raj. is very romantic, he is linked easily to his co-stars.
Vikas & Priya also share scenes among themselves but not shown chemistry on a high level as RN did when he did his initial episodes.
I think all these relationships are occupational hazards of TV actors.
