Sahil Agarwal, a 24-year-old irresponsible young man, returns to his home where his aunt, Bimla, the family matriarch, fixes his wedding to his friend, Nidhi, but he declines and is thrown out. Vedika, who is in need of money rents out a room in her home to Sahil. During this period, Sahil forms a bond with Arya and Manjula, while Vedika tries to keep a platonic relationship between them as a landlady and tenant. Sahil falls in love with Vedika and confesses this, but Vedika rejects him due to their age gap and social problems. Soon enough, she realizes her love for Sahil, though in denial, but eventually accepts it.
A rich man named Yash, who wants revenge on Bimla, makes an entry and reveals his relationship with the Agarwal's. Although against Vedika and Sahil's union, Bimla is revealed to be a hypocrite as she had once seduced a married man, five years younger than her, for his wealth. He then threw out Yash and his mother on Bimla's behest. Vedika is forced to marry Yash. Later, he is diagnosed with cancer and asks Vedika to give him a child. They both decide on IVF, but due to a nurse's mistake, Sahil becomes the donor for Yash and Vedika's child.

Not wanting Sahil and Vedika to unite, Bimla poisons Sahil's mother, Anjana. When she finds out that Vedika is pregnant with Sahil's baby, Anjana happily goes to Vedika's house to propose marriage. Sahil hears of this from Bimla and he too goes to see Vedika. The poison takes effect at Vedika's house, where Anjana falls down the stairs and dies. Sahil arrives at that moment and misunderstands Vedika to be the culprit and has her jailed. In a fit of rage, Sahil marries Bhumi in prison.

Vedika leaves the city with Gauri's daughter and Bimla lies to Sahil that Vedika has abandoned her child. Sahil names the baby Ved and adopts him, unaware that the child is his.
Vedika returns to Kanpur with her daughter, Sadika while Sahil lives with Bhumi and Ved. Arya returns to India after her studies.
