Why didn't they just create a new show?

I can't deny that the actor who plays Shaad and Surbhi have chemistry so no doubt a lot of effort has gone into getting that right but Sahil were meant to THE love story. It's like they're been portrayed as soulmates so I can't imagine them being happy or choosing to be with someone unless Aahil possibly dies and Sanam settles for Shaad though she'd always want Aahil. Because whilst there's been often reasons for doubt on whether Aahil loves Sanam but in my mind there's never been doubt that Sanam truly loves Aahil and if given the chance would want to get her happy ending with him.

I don't know how they're going to do this because Sanam and Shaad have portential and are intriguing but she's already someone elses. If they were in another show I'd like them but she's meant to be with Aahil and was happy and content with Aahil so it wouldn't feel right for her to end up with someone else.

One thing I do fail to understand is why didn't they just end the show with Sehan, Sahil and Tanveer dying and Sanam2 leaving? If they wanted they could invent a new show with Surbhi and the actor who plays Shaad because that's what it feels like, the star of new show. There was no reason to drag the show out for another season with yet another new cast and the leads dying. Instead of dragging this show out with all the baggage and everything, why not sign Surbhi up for a new show with this Shaad guy? Why drag a show that's been on air 2+ years on even further when you could start over without people being upset that you ruined their pairings?

A tip of advice to people who intend to keep watching, I'd be cautious if I were you because so far I think hardly even one main pairing has got a happy ending. The only pairings that get a happy ending on QH is pairings people hardly care about. The lead pairings always end in bloodshed.

Why does this always seem to happen with Qubool hai? Honestly there's no show more manhoos than this.
