All of a sudden they are focusing greatly on humeiras sickness. I have a feeling that the story may be driven by this rather than tannu. I think gul will show zoyaan but I fervently hope that she refrains from zoyaan nikah. Because otherwise I will definitely stop watching.
Today Ayana vowed that he will do everything to keep humeira happy. But humeira is on a suicide mission. So my prediction is that humeira will find out that Zoya is her sister and she will want her parents to have a daughter after she herself dies. So she will ask Ayaan to marry Zoya. Ayaan will pursue Zoya under pressure from humeira. Assad will mistake it for love and will step down so Ayana can be happy. Hence the zoyaan nikah but I hope it all comes to light by then that ayan loves humeira and Zoya will refuse to marry Ayana.
How tannu fits I don't feel like using my brain for that. The less said the better.
