This raises a number of important questions.
1 )I don't think that in places such as where Khanak is living, anyone will come forward to marry a widow, as there is a lot of stigma attached to a widow in such societies. As for Khanak, i don't think anyone will marry her, because Suraj died a day after his marriage - and that will be attributed to her!
2) So perhaps this will force Shaan to marry her?
3) And will Khanak take this second marriage thingy lying down? What if she tries to commit suicide, as she hinted to her mom?
