I think someone proposed it on the forum yesterday and it makes complete sense. Anuj should marry Kavya and Anupama should go back to Vanraj.
This way Anupama can go back to being with acche pita who is the man of her dreams and serving tamashahs. No unnecessary pretense of caring about namesake husband and kid and she can focus completely on the three worthless kids who will never grow up. Shameless Shahs also happy as their slave is back and they can order her about and abuse her at will.
On the other side, Anuj and Kavya both get a much better spouse and most importantly, Choti Anu might get a loving mother who actually cares for her. At one point Kavya had expressed her desire to have a child and she was the only one who was genuinely receptive to CA when she first arrived (3 piggy kids were cold to hostile, acche pita and jhule ki chudail were openly abusive and dukhmukh was fake nice but probably worried about the loss of inheritance of his worthless grandkids)
Kavya might also be a better addition to Kapadia business than an anpadh gawar who acts like a know it all. Anuj can keep funding shitnupamas ventures and the tamashahs as much as he wants on the side.
Somehow, Kavya has been the only character who has seen a positive change over the course of the show. Everyone else has remained the same or regressed. Thoughts??
