The show's main cast includes Ramya Krishnan, Vijayakumar, Seema, and Manju Bhargavi.

Ayyaa's younger sister Mutharasi (Anuradha) is married to Kulasekharan (G.K.), the main antagonist and Naachiyar's elder brother.

Ganga is married to Selvakannan (former: Krishna Kumar, present: Sai Kiran), a well-known and respected IAS district collector.

Since Kulasekharan only wants Ayyaa to be Naachiyar's husband and no one else's, he tries to get rid of Subbulakshmi, Ganga, Ramaa, and Charu, and banish them from the village.

Karpagam initially gives in to Rasammah's talk, but she too begins to love and respect Ganga and her family.

Ganga becomes pregnant, but her child is aborted because she is hit while trying to protect her husband from a raging bull released by Kulasekharan during Vadivu's wedding with Saravanan.

named Vandana, a mysterious and evil girl, who knows that Selvakannan has had a brain tumor for a very long time.

Every doctor gives up on him and tells the family that Selvakannan will die in nine days, and his death is unpreventable.

Kulasekharan is aware of this, and he tries to find out the secret by filing a case against Subbulakshmi, citing that she is not Ayyaa's legal wife.

This was under the decision of the Ayyaa (village head) of the time, Ramachandra Raghunath's father, considering that Kulasekharan and Naachiyar were motherless.

Seeing that things were going out of hand, Ayyaa called for arbitration and stated that Kulasekharan should stay with him until Bhagyalakshmi's child had grown up.

Kulasekharan thinks that Bhagyalakshmi's daughter could be Subbulakshmi since she and Naachiyar are very close, like sisters.

This is unusual because if two women were to share the same husband, there would likely be a lot of jealousy and enmity among the wives.

The groom's side is accepting of the proposal, but they are not satisfied because Kulasekharan threatens to have the marriage not take place, causing the family to be depressed and upset.

The next day, the people in the village find Aravindan's dead body lying in the middle of a path and inform the police and Ayyaa.

They promise to not leak the secret as Kokila is very poor due to her husband's drinking habits.

A minister in the next village finds Subbulakshmi's picture published in the newspaper and calls the number given.

He brainwashes the minister into thinking that his people want to kill Subbulakshmi, and hides from Ayyaa and the family.

Subbulakshmi is held in the police station for murdering Aravindan in her village, and she doesn't tell them who she is and where she is from.

The plan succeeds, but Ayyaa finds out Subbulakshmi's location from a policeman and runs to the jail.

Naachiyar adopted him as her own in order to protect him and his mother from her brother Kulashekaran's wrath as he would have been more enraged against them if he knew Subulaksmi gave birth to Ayyaa's firstborn son.

One of Vandana's mental brothers escapes from a gang and falls into the well while Karthik is thinking about his mother and his wife.

Karthik is shocked to hear that Aravindan was dating a gang member's sister, Bhuvana, whom he cheated on.

He asks Subbulakshmi to meet Aravindan's family so they can learn the truth and convince them to accept Charu.

Karthik pleads with Charu to see Aravindan, as he wants to ask for forgiveness for the miserable mistakes he made in her life.
