The new generation promo says that Ishan will marry Savi to save khandan ki izzat. So, does it mean that Savi was to marry Ishan's brother and he will abandon the wedding due to which Ishan has to marry her or perhaps in business there will be loses and Bhavani would ask Ishan's family to get him married to Savi?? What else could happen due to which to protect khandhan ki izzat Ishan will marry Savi??
So, in a way it is pyaar aur farz but with a different take. Perhaps Ishan will not promise anything to Sharvari like how Virat promised to Pakhi.
