Hearing for so long this is blackmail marriage, Bajaj blackmailed Prerna. Well, It's Basu family who sent Prerna to Bajaj and told her to ask about his demands. Then Prerna went to Bajaj & Bajaj was not even saying anything, she herself asked to make deal with her. Then Bajaj offered a deal that he can free Anurag if Prerna marries him and it was completely Prerna's choice if she herself wanted to fight for Anurag or marry Bajaj. If court declared Anurag as criminal, she could go high court and then she can also find proof by herself, like she exposed Komolika. When everyone was against her. But no, she went to Bajaj, accept his offer. so there is no point of blaming somebody else if Prerna becomes weak this time and didn't fight for Anurag by her own. Bajaj just done a deal for his little Sneha.
