Shakti And Rimjhim Are Both Cousin Sisters..
Shakti Loves Her Family And Shiv.
But Rimjhim She Doesn't Listen To Her Own Sister Shakti
That Keertan Doesn't Love Her His After Shakti.
Hope She Realizes The Truth Soon
Or Suffer The Consequences Of Her Actions..
they can plan RK wedding and then get SS married in veil and sehra saying RK ran away for some reason
and both SS would replace bride and groom to save khandan ki izzat 
But i feel this won't happen.. For Purnendu's prediction to come true Shiv Shakti's wedding will be planned but without Shakti or her family knowing about Shiv's Past or his mental condition.. Which will come to light on the wedding day where Shakti's family would be livid and feel cheated.. Shakti will go against her family and marry Shiv.. Just how Devi Sati went against her father's wishes and married Mahadev..
