Soon it is found that Sanjay is alive and is in care home, taken care by Chandni and Roshni's grandmothers. Chandni saves her father and takes him home with help of Raunaq, Manav and Nirbhay, but Roshni cuts all the ties with Sanjay in anger and due to the insults faced by them in the society. Soon, it is proven that Sanjay is innocent and real culprit is Vikas (Nirbhay's father). Chandni accepts Nirbhay and Roshni's relationship.
