She goes to her family which comprises of her parents, two brothers among whom one is married and has a daughter. After some days, Hashim tells his kids to return saying that he doesn’t want them to compromise their studies with school going on. Henna's happy world got shattered when she receives divorce papers, and she can't even go to the US as she doesn’t have a green card.

Hashim and Kamla marry, but his children refuse to accept her as their mother. Henna desperately wants to meet her children. She meets Nabeel who offers her to take revenge from Hashim, but Henna denies. Meanwhile, children are facing lots of difficulties to stay with Kamla, and even Kamla starts feeling that it is better to send them to their mother, Henna. She makes a plan to send them but gets caught by Hashim who then divorces her. Meanwhile, Marina who is Adeel’s (Henna's younger brother) friend sets up Henna's marriage with her maternal uncle, Salman.

Adeel starts liking Roma and decides to take Marina's help. Marina is in love with Adeel secretly but never confesses because of her inferiority complex as she is overweight. Eventually, Adeel realizes that he loves Marina and then proposes her. It is revealed that Salman is impotent which makes Henna feel betrayed as she didn’t know all this. She even calls him gay, but later she apologizes when Salman makes her realize that she is treating him like Hashim used to treat her. Henna goes to a doctor along with Salman. Marina successfully loses weight and surprises everyone on the day of her marriage with Adeel. Salman gives a job to Adeel in the US, and Henna is pregnant.
Salman is very happy but denies completing his promise,becoming somewhat selfish as he doesn’t want any trouble in Henna’s pregnancy and he thinks that she would neglect her health. Salman and Henna along with Adeel and Marina reach the US. Henna keeps on pleading to let her meet her kids but is denied every time and is promised by Salman that he would take her to meet her children as soon as the baby is born.
Marina decides to apply for her Masters in a university which Adeel opposes, but soon his decision gets changed by Henna. Henna gives birth to a girl who is named Zarlina, nicknamed as Zee.

Salman becomes furious after learning this and goes there with Zee, but Henna blames him for her children’s condition and starts hating him. Salman leaves Zee with her as he is very guilty.
Soni warns Henna to leave the house as she hates Zee and threatens that otherwise, she will create some trouble whereas Naeel likes Zee and plays with her.
