Viswanathan Ramamoorthy

The uncle's will specifies that Rs. 30 lakhs will go to Viswanathan only if Meena behaves well toward him. This condition serves as a test of their marriage - the uncle wanted to ensure that Meena genuinely cares for Viswanathan rather than staying with him purely for convenience. Kathavarayan, the uncle's manager, is responsible for verifying this condition before releasing the funds.

Earlier in the film, Viswanathan is described as timid, suggesting his marriage dynamics may have concerned his uncle.

Shenbagam agrees to impersonate Meena because Ramamoorthy proposes the plan to secure the Rs. 30 lakhs inheritance. The money would help fulfill their dreams - Ramamoorthy wants to become a film director. Additionally, Viswanathan agrees to the scheme, making it a collective effort among the couples to access the inheritance.

The couple arrives in Chennai with dreams of directing a film, establishing their motivation for money.

Meena agrees to continue the ruse because she herself is in financial distress - she was cheated by her manager and needs money urgently. Even though she is shocked to find Shenbagam living as her at first, she realizes the deception could benefit her as well, so she reluctantly goes along with the plan.

Meena's financial troubles are introduced before she returns home to discover the impersonation.

Andal becomes attracted to Ramamoorthy because she believes he is the man who appears in her dreams. This belief drives her pursuit of him and creates romantic tension in the story. Her fascination adds a comedic subplot to the main deception scheme.

Andal's introduction coincides with her attraction, suggesting her dream vision is a key character trait.

Kathavarayan releases the Rs. 30 lakhs after witnessing Meena's transformation into a caring and devoted wife. The impersonation plan, combined with Meena's willing participation to appear loving toward Viswanathan, convinces Kathavarayan that the condition has been met. Several humorous misadventures occur during the scheme before the money is finally handed over.

The will condition requires Meena to behave well, setting up what Kathavarayan must witness.

Andal recalls a memory from a temple feast she once shared with Kathavarayan. This recollection resurfaces her long-lost memories and adds emotional complexity to her subplot. The memory explains her earlier fascination and ties her personal past to the present scheme, revealing a deeper connection between the characters.

Andal's memory return happens after the main resolution, providing closure to her character arc.

Viswanathan decides to produce a film directed by Ramamoorthy as a token of thanks and gratitude. The successful resolution of the inheritance situation, combined with the transformed relationship and renewed bond between the families, leads Viswanathan to support Ramamoorthy's directorial dreams.

The couples' collaboration throughout the scheme builds toward this moment of mutual support.

Kathavarayan is the manager of Viswanathan's late uncle, which is why he is tasked with overseeing the inheritance. He arrives with his daughter Andal to verify the condition in the will before releasing the Rs. 30 lakhs to Viswanathan. His role creates the opportunity for the deception plan to unfold.

The uncle's will directly names Kathavarayan as the person in charge of the money.
