What if the situation unfolds as follows. Siddhi deliberately fights with Kunal and the family yelling things like she was coerced into this marriage etc. She signs the divorce papers. Richa comes and says she struck a deal with thakrals for money. Chopras hate her. But Kunal doesnt. He has an unshakeable faith in siddhi and his love.
He doesn't beg her not to divorce him. Rather with akad points out that she can't divorce him till she is pregnant and even after that he will fight for thr custody of the newborn. Siddhi is forced to live in the Chopra house. She taunts kunal to make him hate her but he refuses to change his love for her. then richa realizes that the baby is keeping them together and tries to cause a mc. Kunal saves siddhi in the nick of time and in that charged situation siddhi tells kunal everything.
Kunal is furous but decided to act with hosh not just josh. They play richa's game on her fooling her that sinal are indeed separating and kunal wants to get back to her. They eventually trap richa flor rohit''s murder, Daddy T goes mad hearing this
Kunal and Siddhi live together..and then maybe richa escapes jail again and runs away with one kid.
