Well If we go by the Opening episode, it clearly showed that a LOVE TRIANGLE will happen between the two. If you see carefully you will notice that in the second epi it was Asad who first spotted Zoya and got attracted instantly. But then he closed his eyes and pretended to ignore while Ayan went out to follow her. Asad opened his eyes, found her gone , therefore accepted it but Ayan kept looking for her. At the end though it was Asad who encountered Zoya , NOT AYAN.
So I feel even though there might be a triangle ,It will be Asaya eventually.
4 Lions shows always have layered scripts and there are hints ON & OFF regarding the future track. Yes tracks DO CHANGE based on public demand and this high TRP is mainly because of Asaya Jodi ,but IMO a triangle won't be so bad as long as the leads don't get seperated for long and Zoya Ayan marriage should not happen at any costs.
Btw forgot to mention in the first episode the ending shot where Zoya is shown in between Asad and Ayan , it clearly shows a love triangle.
