Zoya is a progressive Muslim girl. She is a beautiful and intelligent girl who is contemporary in her approach.

She has had an upper middle class upbringing but she has no hassles in interacting with people above or below her social status.

She is vivacious and talkative but does not open up to people about her private life easily. She is adventurous by nature but sometimes lands into trouble for being foolishly so.
