Anandan became temporarily separated from his wife Parvathy after an anonymous letter was sent that slandered her character. This letter created doubt and tension in their marriage, leading to their separation. The letter was later revealed to have been fabricated by Anandan's uncles to drive a wedge between the families.

Parvathy is the same woman in both Vinu and Anandan's lives - she is Anandan's wife, but she was also Vinu's ex-girlfriend from five years before the story. Vinu never fully moved on from their breakup, which is why he was struggling emotionally despite being engaged to Anjali.

Vinu's inability to move on from his past relationship is established early in the film.

When Vinu discovered that the Parvathy he loved was Anandan's wife, he felt it would be awkward and uncomfortable for everyone if the wedding proceeded. He feared the situation would create tension between the two couples and tried to delay or stop the wedding to protect everyone's feelings.

The anonymous letter was not written by Vinu, as Anandan suspected. It was actually fabricated by Anandan's own uncles who wanted to create conflict between Anandan and Parvathy. They kept this deception hidden from Anandan because they knew his temper would escalate the situation.

The uncles' animosity toward the family is hinted at when they join forces with those trying to stop the wedding.

Anandan suspected Vinu because he learned that Vinu's ex-girlfriend was his own wife Parvathy. He believed the love letter that reached Parvathy could have been written by Vinu, thinking Vinu was trying to reconnect with his former lover and ruin his marriage.

Anandan's uncles deliberately sent the anonymous letter to slander Parvathy and create a rift between Anandan and his wife. Their motive was to cause trouble for the family. They later joined forces with those trying to stop Vinu and Anjali's wedding, adding another layer of opposition on the wedding day.

The uncles are mentioned as having their own agenda against the family early in the conflict.

On the wedding day, Anandan learned the truth about the letter from Parvathy's father and his own parents. Realizing his uncles were behind the deception, he joined forces with Vinu to fight off Saravanan, George, Kunjunni, and the uncles' goons. With his father Sudevan's permission to protect the family, Anandan quelled the disruption and the wedding proceeded.

Yes, Vinu and Anjali do get married despite all the chaos and complications. The wedding proceeds with Anandan's support after the truth about the letter was revealed. Both couples - Vinu with Anjali and Anandan with Parvathy - end up happily married, with the families reconciling.

Kunjunni initially refused to help Vinu stop the wedding because Anandan was his longtime friend from school. However, after Vinu slapped him during an argument, Kunjunni switched sides and joined Anandan to help stop the wedding. His change of heart added another opponent to Vinu's efforts.

Saravanan was once Vinu's friend but became an adversary after Vinu inadvertently ruined a marriage opportunity for him. He returned specifically to disrupt Vinu's wedding. George was a stalker who had previously tracked Anjali and also joined the effort to derail the ceremony, adding danger to the wedding day chaos.
