Aisha is a budding writer and an independent, progressive woman from Mumbai who visits Delhi with her friend to research for her upcoming book. She meets a local guide, Dev, and falls in love with him. She later proposes to him and they get married. After a few months, Aisha realises that she is pregnant. Dev is extremely happy but Aisha is reluctant as she feels she isn't ready for parenthood. Dev convinces her and they both settle into happiness, feeling that they might have a baby girl who they will name Disha, a combination of Dev and Aisha's names. Unfortunately, Aisha has a miscarriage and Dev's mother blames Aisha for it. Aisha feels humiliated and insulted and leaves Dev. A few days later, Dev and his family try to bring her back but she doesn't return. She calls Dev to meet her at a certain place if he really loves her, but Dev does not come. Seven years later, Aisha calls off her second wedding as she is still in love with Dev. She decides to face her problems and travels to Delhi. On her way, she meets a woman named Anu and her daughter, Pulti, and discovers that Anu is Dev's second wife. She also meets Dev in the same train. During the journey, she reminisces about her marriage with him. She also finds out that Pulti’s original name was Disha, and feels upset, chiding Dev for naming her that. Anu also reveals that Pulti was not Dev's child but Anu and her lover's. Dev lifted at the very next moment he saw Pulti and before marriage he had a single condition that she should be named Disha. The train reaches Dev's station. While leaving, Anu thanks Aisha for giving her Dev and tells her that she knows that Aisha is Dev's love and first wife. Dev disembarks the train, but returns to tell Aisha that he had come to meet her that day but somehow felt that she couldn't remain happy with him. His world is different from hers and he wanted to see her living her life happily and fulfilling her dreams. He reveals that it was because of this why he hurried through divorce proceedings, and appeared as a bad person before her. He also tells her that he had read her novel many times. Both cry and hug each other. She says that although their destinations are different, their love remains intact. Dev tells Aisha that he will wait for her next novel, and they part ways, to live two different lives and two different destinies. A year later, Dev finds Aisha's new book named Jalebi, which is an account of their love story.
