Raja Rani (Tamil TV series)

The plot focuses on the story of Semba aka sembaruthi, a maid working for the Rajasekar family. Both Rajasekar and his wife Lakshmi treat Semba as their own daughter, but their daughters-in-law Archana (Sridevi Ashok) and Vadivu and Rajasekar's elder daughter (Nandhini Vinoth) worry that Semba will inherit part of the family property, reducing their own shares. They mistreat Semba. Karthik is Rajasekar's youngest son and returns to Chennai after a period spent working as a scientist in Singapore. Karthik takes a stand against the difficulties Semba faces.

Karthik's girlfriend Divya comes from Singapore to visit his family. Vadivu's brother Sanjay attempts to seduce Semba and is stopped by Karthik. Karthik has the idea that Semba should marry, and uploads Semba's profile to a marriage website. A groom comes to visit, but Sanjay intercepts him and tells him lies about Semba, so he leaves without meeting Semba. Archana brings in a groom who is a distant relative, and an alcoholic. This groom's family proposes marriage within two days, and Rajasekar's family accepts the proposal. Preparations for the wedding are in full swing when it is discovered that the groom is still married to his first wife, whom he abandoned.

Meanwhile, Karthik and Divya are planning to get engaged on Semba's wedding day. Divya goes to the airport to fetch her parents, who are arriving from Singapore. Semba's marriage is stopped and Rajasekar is blamed by everyone for Semba's pitiable position. Rajasekar, who is in a devastated state, persuades Karthik to marry Semba to mitigate the disaster of the failed wedding. Divya arrives at the last moment, just in time to see the wedding become official. Divya asks Karthik whether he married Semba only out of pity, but Karthik remains silent and she leaves, angrily.

After Divya leaves, Karthik allows himself to show his anger by throwing things. Karthik's mother realises for the first time that her son has been sacrificed. She too becomes furious and turns against her husband, and eventually against Semba. Semba does not expect Karthik to treat her like a real wife, so she continues to work as a maid. One day Lakshmi's friend comes to meet Karthik's wife, not knowing the history, and she criticises the family for marrying a maid to their son. Humiliated, Lakshmi is persuaded by Archana and Vadivu to call Divya back. Meanwhile, Rajasekar plans to hold a reception for the newlyweds. No one supports his decision except his brother Chandrashekar, youngest daughter Vinodhini, and her fiancé Harish.

Divya comes to the reception of Karthik and Semba and creates drama when Karthik accepts Semba as his wife. Then the couple prepares to spend their first night together. But Lakshmi suddenly begins to have chest pains. Karthik panics and stays with his mother. Since she is not allowed to see Lakshmi, Semba sleeps alone in the room that she was to share with Karthik. This event is a turning point, as Lakshmi and Karthik begin to appreciate Semba. Archana, Vadivu and Sanjay all try to undermine Semba and make her leave the house, but the result is that Karthik begins to fall in love with her.

A beauty competition leads Archana to overwork Semba giving her beauty treatments. Karthik becomes angry, and makes Semba participate in the competition, which she eventually wins.

Karthik entrusts Semba with documents relating to his confidential project hon topics to do with space and the military. Archana, Vadivu and Sanjay steal the documents and put the blame on Semba. Karthik is angry and says humiliating things to Semba. Semba finds the documents and reveals that Sanjay was the thief, but is so humiliated that she leaves the house. Karthik later finds her and brings her home.

Karthik and Semba's relationship becomes stronger, and Karthik confesses his love to Semba and she accepts. Meanwhile, Divya offers Karthik a job without revealing her identity. Karthik and Semba go to a party to celebrate Karthik's new job, and find Divya there. She was previously married to Vicky, a rich 65-year-old businessman, and is wealthy.

While Karthik is working at her company, she moves into Karthik's house as a guest and tries to get help from the family to separate Semba and Karthik. Archana, Vadivu and Sanjay agree to leave Karthik alone in the house, in return for Rs.50,⁰00,000. Divya drugs Karthik; while he is unconscious, she tries to have sex with him. Semba uncovers Divya's plot.

Vinodhini, Karthik's youngest sister, is engaged to Rajasekar's friend's son Harish, but Vadivu's father Devraj wants his son Sanjay to marry Vinodhini instead, to gain control of Rajasekhar's family. When Harish's family asks about the dowry, Devraj increases the dowry to stop the marriage. Rajasekhar is not very well off at the moment, but decides to take his savings of Rs.80,00,000 from his bank. But his cheque bounces. The bank manager says that Rajashekar's elder son Amudhan has forged Rajashekar's signature and emptied his account. Devraj, knowing this, has set a trap by making Rajashekar's house security for a loan of Rs 50,00,000 Lakhs, carrying interest of 0.2% per week. At Harish and Vinodhini's marriage, the money lender stops the proceedings by demanding his weekly interest, as Devraj planned. Finally, Rajashekar sells his house to cover the debt. Harish's family members were humiliated by this incident. Archana and Vadivu fight Harish's family and Harish's mother is injured. Kathiresan, Harish's father, then cancels the marriage. The marriage hall manager demands to be paid for the costs of the wedding, and all the family members except Archana and Vadivu give up their gold and jewels including Semba's thaali, the marital holy mangala sutra necklace.
