As the promo tells that kasturi said the person to whom I'll give the right to put mangalsotar will be:
In My opinion she will say thts runak who can put manglesutar.(mujhy wo mangalsotar pehnaie ga jo meri kushy chahta hai)
It will the payback towards Robbie for all the insult etc as kasturi give priority to runak on him. He'll feel very sad and embarrassing. And will ask her to forgive him and he'll apologies for all his misdeeds to her family and will tell him tht its all the result of misunderstanding . Then the real scene creates when runak'll say that my happiness will be in if kasturi makes her mind for Robbie as she loves him(meri khushi ye the ke tum Robbie ko choose karo) and only she can turn Robbie into a really nice person and also he will explain all his past to her and entire kasturi's family(he may be a patient of any serious desease or it might be the case tht shevani put a serious ilzam on him and went away ,what ever the story). The marriage will be cancle or may be postpond for 2 or 3 months(as its Ekta's serial) after knowing the horrible past of Runak. And during this time period everything will be on its way back and kasturi will decide for Robbie again😃
what's ur opinion?????
