Why cant Tanveer be positive?

Why is it a necessity for the third angle to be negative for the leads to understand eachother's worth?I have never understood this logic in desi soaps..Given the emotional connect Asad and Zoya share, shouldn't Asad be pulled towards her even if Tanveer is the most tehzeeb se bari ladki in the world?Wouldn't this have greater depth and impact than a scenario where Asad realises Tanveer is a conniving bitch and reverts back to Zoya? Am sure there is going to be a huge misunderstanding between the two once this plan is revealed..Now after all this, wouldn't it be awesome to see Asad unable to move on and forget Zoya despite Tanveer being the perfect wife material he has always wished for? This i feel will be way better than Asad deciding to go back to Zoya after seeing Tanveer's real face..On the other hand, even if they decide to make Tanveer negative, i hope they show Asad going back to Zoya even before her true face is revealed..This would be a refreshing change and it wouldn't seem like Zoya was Plan B given that Plan A failed😆 I know am jumping the gun but i hope they don resort to the cliched route shown in most shows..

Agree with you...I was also thinking the same.. If CV's show this then it wil be proved that Asad's love for Zoya is beyond everything..
