Aliyha Malik (Ally Brooke) is Zayn Malik's twin sister. When Tricia─their mom─ was pregnant, she expected a boy which is Zayn, but each day her bump grows, she realizes that she is carrying two babies in her belly which is Aliyha and Zayn. Since she knew that she is carrying two babies (unexpectedly) she didn't want to raise Aliyha. Years passed and the time came when Zayn had to audition for X Factor and leave Aliyha behind, Aliyha suffers for the consequences she faces during her time with their family without Zayn.
