it can only be Jawahar as per current situation.. all family members are away except him... Moreover Chanchal seems to know that Nivi would be put in trouble when she is alone... she purposely insists on having dinner at HLs house so that Niv could be troubled.. Chanchal And Jawahar are the only ones who would want to harm Dadaji for apparent reasons... Dont think YSD is part of the plan ... she would not allow these ppl to harm her husband...
Only stupidity of the show is hiding face of the stalker... the two are black characters .. what is the need to create suspense really.. unnecessary and stupid track... they might end up losing more audience when this is revealed...😕
