Story wise and what we have seen, technically it should be asad / asya cause of the multiple engagements and because they are trouble free atm and in love and cravin to marry.
But i think itll be either asad or najma
Ayra and asya i think will marry at the same time (i still think that) and even if tey dont, ayra i think is in a shakey place right now so i don think they willarry just yet.
Noozhat obvi not lol.
Nikhat i REALLY think farhan is coming for her so i expect them to show her love story and so i think her marriage will come a bit laterz
Leaving asya and najma.
I really dont think asad and zoya will marry before najma. I think they will make sure najma is married before they marry. So what im thinkin will happen is najma will go to alter an her marriage will be broken by zoe herself, because of which asad may not marry her cause it wont be right to marry after his sisters rishta is broken.
Or it could be that najma and zoe fight and doesnt believe zoe so she goes ahead and marries imran anyways after which asya marry.
Or it could be that najma relationship breaks but asad and zoe will still marry maybe on behest of dilshad saying not to wait this time, or maybe asad pressuring cause he wont want to loose zoe this time not matter what.
Basically i think its asad or najma. And technically it should be asad.
