However, things take an unexpected turn when Aman's girlfriend, Shreya Arora, a career-oriented fashion designer with a lot to learn about children, joins the family. When Aman introduces Shreya at Anjali's birthday party, she accidentally drops Anjali's birthday cake, which leads the children to perceive her as evil. At a fashion show, Anjali helps Shreya with one of the outfits for the models. When Shreya goes to get ice cream for the children, Aaliya tells her siblings that she is using them so she can take their father away, and Anjali goes missing after. At the police station, Anjali is found and Aman tells Shreya that she cannot go near the children without Maya's permission. Maya finds out that she has cerv ical cancer and tells Aman, which prompts him to move back in with the family and leave Shreya. However, he is unable to forget her, which Maya notices. Maya tells their children that she has cancer and Aaliya retaliates by going to a party with an older boy. Maya then tells Shreya that she has cancer, and tells her she wants her to take care of the kids after she's gone, as they’ll need a mother in their lives.

After the argument, Aman tells Maya that they should not be competing with each other for the children's love. Maya faints and is brought to the hospital, where the doctor tells her that she has only a few days left. Shreya decides to take care of the children while Aman tends to Maya .
