sharam marriage wl start and at 7th round ishita will enter the house
raman wl nt be able to complete the round and run towards ishita saying how much he loves her and can't imagine his life with anyone else
bt ishita wl by then have met nidhi who will warn her that if ishita says anything to anyone and even tell her that if she ever returns to Raman's life,she wl harm ruhi.
so nw ishita to save ruhi wl play the sacrifice card and tl raman that she hates him and wl marry mani.
just my guess
