That's a tricky question actually. Here's why: the shows is built around the conflict between the two families, NOT just Thakur and Jagmohan. It's open season on everyone...the cliche "all's fair in love and war" comes to mind.
We've got two MEN; hence it will always be a war. I myself would love to see Jagohan pity his son and let him marry Abha. He probably would not give up on Thakur though, and for the sake of the show, I hope he doesn't. We also have Shelly and Vimal and that witch Kanika, so there is no dearth of bad people in the show and there is enough conflict to move ahead.
How does Abha handle the conflict between her father and father-in-law? What would happen in Swarn Bhawan? What intrigue will pop up?
I think that the two fathers are so wrapped up in their egos that they forgot about their kids a long, long time ago. They will never allow their children to be happy. But I wish we could have seen Karan and Abha together now, and how that changes their families.
