Hence, Bhoominathan and Swaminathan reunite with each other. Both of them blackmail Sanjay by telling him that they have given poison and Swaminathan brings back Bhoominathan's company to him and it is proved that Sanjay is the actual murderer. At that time the evidence that Sanjay was the murder of Angayarkanni which was kept in a doll is taken away by Riya and finally the evidence reaches Swaminathan and Rani. After some turns of events, Sanjay plans to murder Swaminathan and Rani. Bhoominathan and Jyothi believed that Swami is the person who murdered their mother and a fight occurs between Bhoominathan and Swaminathan. Meanwhile Angayarkanni was murdered by Sanjay and made Swaminathan as the victim. Neela blackmails Saravanan and Surya in one way to take money from them and Sanjay takes Bhomminathan's company with the help of Sudhakar and creates a confusion between Swaminathan and Bhoominathan. Then Akilandeswari and Sudhakar started a new plan with the help of Neela and Sanjay. Akilandeswari helped her and started blackmailing Rani and forced her smuggle drugs but finally with the help of Rani and Vani, Thenu regained her memory. Chandrika treats her like own daughter Bhavani who died by jumping from the hill and she never wanted to give back Thenu to Rani.
She rescued by Chandrika (Madhuvanti Arun) and her brother. After a sequence of events, Thenu fell down from a hill top and lost her memories.
Her jealous aunt Krishnaveni (Nalini) wanted to amuse his wealth which was given by kokila's dad, with the help of Jessy who looks like kokila. Meanwhile in Australia, Swaminathan had a relationship with kokila who actually died. So, Akilandeswari wanted to take revenge against Vani and Rani family. Janani was murdered by Sudhakar, Akilandeswari's brother but he made Vani as the victim. Rivalry started between Vani and Akilandeswari (Mamilla Shailaja Priya) because of Surya's relationship with her daughter Janani (Priya) during college days. Saravanan gets married with Pavithra (Shruthi Shanmuga Priya). GP tried killing Kathir but finally got arrested by Gautham. Then due to rage of Gautham killing Arya, GP vows to destroy Vaani's family and that will lead Pooja's uncle Kathir to revenge GP by mysteriously killing GP's henchmen and trying to destroy his businesses and his criminal network. GP is also a big business magnate who controls the Indian medicine mafia activity and his son Arya (Fawaz Zayani) was a big criminal dealing in international illegal organ mafia activities. Gautham becomes a police man and investigates a murder that took place in a quarry which was owned by a doctor known as GP (Tarun Master). Surya and also Dimple wanted to divorce each other several times, but at the end, Vani was able to bring back them together. She hates Vani and does everything against her mother-in-law. Selvi also faces numerous problems through her father in law, Kaali (Baboos), Alamelu and Shenbagam (Sumangali and Shreedevi), Shiva (Jai Ram) and Geetha, and later on through Kaali's daughter, Malathy (Minnal Deepa). While Jyothi's daughter Poongodi (Mahalakshmi) is involved in a love triangle between Karthi (Rajkumar), and Saravanan. Kadhir turns into a good man after Pooja's marriage. After many incidentes and obstacles Gautham marries Pooja to rescue Saravanan from Kadhir. Gautham threatens Kadhir to leave his family alone. However, problems continue to haunt them in the form of a vengeful Angayarkanni and Jyothi and Kadhir, a local don who has his vengeance against Saravanan.
They get together but live in separate houses. However, Bhoominathan later realises his faults, turns over a new leaf and sends his mother away and tries to get the family together. Meanwhile, Selvi falls in love and under dire circumstances,marries Rajesh (Guhan Shanmugam) with only Vani as a chance witness, causing a rift in the family, and their eventual separation, resulting in Vani and Rani to get separated. Problems continue to erupt in the house due to Bhoominathan's ego against his stepbrother, while the entrance of Angayarkanni, who is jealous of Vani and Rani's close relationship despite Vani's refusal to ever directly address Rani, further worsens the problems, by conspiring against them and trying to separate them. Vani has two sons, Surya Narayanan (Arun Kumar Rajan), an unemployed and childlike lawyer and Gautham (Vignesh Kumar), the college guy,while Rani has three children, Saravanan (Maanas Chavali), Selvi (Niranjani Asok) and Thenmozhi (Neha). However, they all live together in the same house. Over the years, Vani and Bhoominathan turn out to be very successful, while Rani and Swaminathan are not too successful since all of Swaminathan's business turn out to be failures.
