But the only thing is that she doesn't have the liberty like we do of Niraj and Nibir because if Nibir does become a proper couple but Viraj still loves Nisha I think she would have to support the couple who loves eachother (whoever it may be) and she would be able to explain/comfort lovingly to whichever son who got their heart broken. And it would be better for Viraj to because he would have someone to love him and he wouldn't feel that craving as much anymore.
Or I could be completely wrong and Nisha doesn't choose either and she just continues her normal life with her cousins and along the way something (or someone else) could happen.
But oh well, I guess the future is uncertain, as it always has been.
