I am new here and this is my opinion. Let me know what you guys think.
25 years ago...Rashid and Dilshaad are married with Asad as their son. Shireen falls in love with Rashid and Rashid has an external married affair with her. Through that affair are born Ayan and Nikhat. The affair is kept a secret from Dilshaad for a while, but she finds out about Ayan and Nikhat. To give Ayan and Nikhat a father's name, Dilshaad bring Shireen, Nikhat, and Ayan to her home.
After about a year or two, Shireen's Bother has another girl, Humaira and finds out he can't have any more children (especially a boy). Since Shireen already has a boy, he plans to make Ayan his heir, but he wants to raise the boy to his image. He can't just take the boy from Rashid and Shireen.
While in Rashid's house, Dilshaad has given birth to Najma as well. With the # of people, Rashid is not able to afford all their expense. The whole family is suffering and they can't find a way out.
In walk Shireen's brother with the promise of wealth and comfort. His first condition that Rashid divorce Dilshaad and he marries Shireen. Second condition, Rashid and Shireen, with their children, come live with him. Since he only wants Ayan not Asad, his third condition is that Rashid never see Dilshaad or her children again.
Rashid hesitates but his mother forces to make the decision. Since Shireen is pregnant again (with Nusat), he accepts the conditions.
For 17 years, Rashid, Shireen, and their children live in comfort. Dilshaad and Asad work hard to make ends meet and to raise Najma.
