Basically, as a viewer, it has been very hard to decipher Zoya's status. But given that we know the storyline a little, I do think Zoya is going to fully fall in love with him during the course of her marriage/contract with him (IF such a track happens).
Edit to add: I tend to take a cue from the background songs they use. During their return from mangalpur in the tractor when they played 'adhoori kahani' I was starting to think that Zoya does feel a little something deeper for Asad.
