after all this show is all about BR...so not sure whether raina's past will be given that much importance unless she is star related to BR who could free him of this curse, rishab is out of question... there is sure a positive relation between BR and raina, but she can't be his niece since before the show started it was everywhere said the show will be based on jaani dushmann and beauty and the beast ...jaani dushmann part they have shown but there are no signs of the latter yet... raina likes/loves rishab though not sure about rishab ...now from the sbs segment seems raina will be helping BR *kinda befriending the beast*... think sanjay who was cursed due to one beauty aparajita may get freed n be back as sanjay due to another beauty raina on a particular poornima night, at the end...
