Ayaan & Zoya..

I hate the thought of it, but it could happen unfortunately.

Maybe she finds out who her father is, and from Ayaan she finds out that he is being forced to marry Humeira, and since Ayaan believes that Humeira doesn't have feelings for him, he tells this to Zoya.

To save her sister from being forced into an unhappy marriage, she decides to marry Ayaan instead, and this way she also gets to be close to her father, as both Ayaan and him live in the same house.

I hope it doesn't happen. But this would be the only way I could digest their marriage. I don't think any of us would want to watch the show if it's shown that Ayaan and Zoya fall for each other.
