It seems there are many episodes which you did not watch. I also missed many episodes. But I could gather the story through updates posted here.
A couple of months back 20 year leap happened in kzk. Before the leap, Bajaj and Anurag were face to face. Sam was hiding behind a tree and she shot Bajaj. At that time there was a gun in Anurag's hand. When Bajaj was shot, then Prerna reached there. She thought that Anurag had shot Bajaj. Anurag kept on shouting that he had not done this. But Prerna did not listen and she shot Anurag. Everybody thought that both Anurag and Bajaj were dead.
But somehow Anaita saved Anurag. She took Anurag to a hospital. His face was badly damaged. Doctors did plastic surgery and he got the face of Hiten (Karan of ksbkbt).

Then the leap happened. In the meantime Anurag became a very rich businessman. He kept his name as Pratham Mittal. Other than Anaita nobody knew that Pratham Mittal was Anurag. She somehow convinced Anurag that Prerna was treating Sam (Anurag's wife) and his children as slaves. This made Anurag hate Prerna. After some episodes came to know Pratham's reality and after that Sam also came to know. Now Sam is creating differences between Pratham(Anurag) and Prerna.
