Plot
Charming, flamboyant Zain, and pretty, cultured Aaliya have been rival cousins since childhood. They eventually grow up and meet again, but a series of misunderstandings lead them to marry each other. Zain wants to get rid of his "Maammu Ki Bhanji" aka Aaliya as he calls her, as soon as possible. He does not believe in the institution of marriage. His brother, Fahad has two wives, Nafisa and Shazia who hate each other.
Fahad's mom Suraiya wanted a grandson; Nafisa was unable to conceive anymore after having two girls. So, Fahad married Shazia and they had a son. He loves both his wives. Zain Aaliya constantly bickers, but slowly with time, "KitKit and MKB" finally become friends. Zain is injured in an accident. The accident was caused by Rocky, a brothel owner who tries to deceive Aaliya's sister Aayat, but Zain saves her and puts Rocky behind the bars. This accident however brings Zain and Aaliya closer to each other.
Suraiya emotionally blackmails Aaliya, making her leave. But Zain brings her back. Fahad and his father Usman plan to make Zain and Aaliya fall in love. Suraiya dislikes Aaliya and her family because Barkat, her long-lost daughter was kidnapped by Aaliya's estranged uncle, Mir Khan. Zain and Aaliya finally find Barkat. Joyous, Suraiya starts liking Aaliya and her family again, which makes Shazia and Nafisa unhappy.
Zain and Aaliya finally realize their love for each other. Zain feels jealous whenever he sees Aaliya and Zubair together (they are cousins, actually). On the other hand, Nafisa's brother, Rizwan has fallen for Aayat too. Out of angst, Zain unintentionally hurts Aaliya's feelings, who leaves for her hometown Bhopal and leaves a message asking him to realize his mistake. Zain reaches Bhopal and after escaping a tragedy, Zain-Aaliya finally confesses their love for each other and returns home happily.
Aaliya soon finds Barkat's behavior suspicious, and it is revealed she is actually Mir's biological daughter who is after the Abdullahs' family wealth and property. Zain and Aaliya expose Barkat, who is thrown out of the house, but before going, she poisons Suraiya's mind against Aaliya, telling her she is having an affair with Zubair. Thus Suraiya again starts hating Aaliya.
She plots to separate Zain and Aaliya by creating misunderstandings between them. Due to a major misunderstanding created by Nafisa, Zain begins hating Aaliya, unknowingly. Usman meets with an accident and become paralyzed and Aaliya is held responsible for that as she was the one who sent him to the office.
Aaliya gets help from lawyer Rehan, a single father of two children, and a family friend of the Abdullah's. He tries to get to the bottom of the truth regarding the arrest and finds out it was Nafisa. He plots a plan to make her think Usman is alive, which frightens her and causes her to expose herself before him.
Aaliya is still hurt by Zain's mistrust in her and decides to start afresh somewhere else. Having realized her wrongdoings, Nafisa apologizes and tells Aaliya to not reveal for the sake of her daughters. Aaliya forgives and tells her she's moving away. Rehan sends Nafisa's recording to Zain, who realizes his mistake and rushes to stop Aaliya but it is too late. He breaks down but vows to find her and win her back.
