Aagasaveeran runs a roadside
eatery with his family. He's engaged to Arasi "Perarasi", a double degree graduate, and both families have agreed to the union. Perarasi develops feelings for Aagasaveeran due to their shared passion for cuisine. However, her brother Porchelvan discovers Aagasaveeran's family has been involved in rowdyism in the past. This, combined with Aagasaveeran's lack of graduation, contrary to his mother Pottu's claims, leads Perarasi's family to call off the marriage. Aagasaveeran's father, Sembaiyya, meets Perarasi's father, Arasaangam, and Porchelvan, and assures them that his family now leads a peaceful life. Despite this, Perarasi's family remains resistant to the union. On
Diwali eve, Aagasaveeran visits Perarasi's house to inquire about the marriage. Despite resistance from Perarasi's family and an attack by Porchelvan's henchmen, Aagasaveeran takes Perarasi with him and marries her in the presence of his family. Perarasi's family cuts ties with her, but months later, Arasaangam forgives her, and the family reunites. Three months into her marriage, Perarasi starts to bond with her in-laws. Sembaiyya gives her a symbol of authority by making her sit at the cash counter of their hotel, a position previously held by Pottu, thereby making her feel humiliated. As the eatery expands into a hotel, it's renamed "Perarasi Hotel," which sparks envy in Ragavarthini, Aagasaveeran's sister. In retaliation, she takes over the cash counter, demoting Perarasi to serving as a waitress and performing table-cleaning duties. Despite this, Perarasi continues to work hard out of love for Aagasaveeran. Pottu further burdens Perarasi with various tasks, including washing vessels, cooking, and serving. Aagasaveeran, unable to confront his family, motivates Perarasi to persevere and helps her with the workload. Meanwhile, Perarasi's mother, Aavarnam, begins to manipulate Perarasi into separating from her in-laws, believing that a separate life would bring happiness to the couple. This leads to frequent verbal arguments between the couple, and Perarasi frequently returns to her parents' home. Each time, Aagasaveeran pleads with her to come back, and she forgives him, believing his mother and sister are the root of the problem. As time passes, Perarasi becomes pregnant, and Aagasaveeran lavishly spends on her baby shower function. However, Perarasi soon discovers that Pottu is secretly planning his marriage to his cousin, Azhagi, without his knowledge. Perarasi informs her brother Porchelvan about this, and tensions rise between Perarasi, Ragavarthini, and Pottu. Perarasi's doubts about Aagasaveeran's relationship with Azhagi lead to a violent outburst from Aagasaveeran, and in a fit of rage, he attempts to commit suicide by jumping into a well but is rescued after several hours. Meanwhile, Porchelvan and his men arrive at Aagasaveeran's house, brutally beat his family, and take Perarasi and their toddler away. Aagasaveeran tries to avenge, but Porchelvan escapes and uses his acquaintance,
Inspector Chithra Krishnan, to file a fake complaint against Aagasaveeran's family for abusing Perarasi. With Chithra Krishnan's support, Porchelvan permanently separates Perarasi and Aagasaveeran. Both Aagasaveeran and Perarasi visit temples and perform several rituals individually for their reunion. At the Thoondi
Karuppusamy temple, a family deity temple of Aagasaveeran, Perarasi, and her parents arrive for her toddler daughter Magizhini's head tonsuring ceremony without Aagasaveeran's knowledge. Aagasaveeran arrives, intent on taking his daughter back, and interrupts the ceremony, beating the barber Soman. Also, Perarasi's paternal uncle pulls out a hidden gun, which accidentally gets into the hands of Amarasigamani's son, Aagasaveeran's distant relative, who had coincidentally come to the temple for his son's birthday celebration. Aagasaveeran's younger brother joins the fray, leading to a scuffle between him and Arasaangam. At the temple, a petty thief named Chithirai Kumar "Chithirai" is also present, for whom Inspector Parivendhan is searching in connection with a recent theft at
Othakadai. Poonganagar Kumar "Madapuli", a drunkard inadvertently informs Parivendhan about the fight between Aagasaveeran's family and Perarasi's family, and Parivendhan heads to the temple to intervene and also to apprehend Chithirai. Soman, who was beaten by Aagasaveeran and his brother, seeks help from his union and his drunkard relatives. At the temple, Pottu appeals to the
MLA to help resolve the family dispute, and the MLA assigns village officials to mediate. Perarasi requests a divorce from Aagasaveeran, and her relatives demand that Aagasaveeran's family return her jewels before the separation can be finalised. Ragavarthini's husband, Nagappaambu, arrives with the divorce documents and the pawned jewels of Perarasi. Aagasaveeran wants to reunite with his wife and daughter, but both families are determined to keep them apart. Amarasigamani intervenes, sharing a similar experience with his sister, and urges the couple to reunite. However, Porchelvan's goons arrive, and Aagasaveeran brutally attacks Porchelvan to avenge his family's earlier assault. Nagappaambu insists that both parties sign the divorce papers, revealing that his wife Ragavarthini's actions contributed to the separation due to her feelings of neglect. As the divorce papers are about to be signed, Pottu has a change of heart, realising she'll be separated from her granddaughter Maghizhini. She asks Aagasaveeran not to sign the papers, but Aagasaveeran decides to sign them anyway, citing the ongoing interference from both mothers-in-law. In a dramatic turn, Pottu takes Maghizhini and escapes in an auto, with Aagasaveeran and Perarasi joining her, after she confessing that she can't live without Aagasaveeran, and Porchelvan chases them. The trio stops midway, and Aagasaveeran and his brother fight back against Porchelvan's henchmen. Perarasi stops Porchelvan and Aagasaveeran from fighting, and Arasaangam intervenes to prevent Porchelvan's friend from attacking Aagasaveeran. It is revealed that Porchelvan's friend had been lusting after Perarasi and had previously spread false information about Aagasaveeran's family to sabotage their wedding. It turns out that Arasaangam had secretly arranged for Aagasaveeran to attend the head tonsuring ceremony with the help of Logu, a cab driver. Arasaangam slaps his wife Aavarnam for brainwashing Perarasi against her in-laws. Porchelvan, realising his friend's true intentions, seems to let go of his animosity towards Aagasaveeran, but a hidden tension remains. Pottu clarifies that Azhagi is the bride for Aagasaveeran's younger brother, not Aagasaveeran, dispelling Perarasi's misconception. Aagasaveeran apologises to Soman for slapping him and pays off Soman's drunk relatives to calm them down. Inspector Parivendhan arrives at the scene, only to find the family at peace. Later, Amarasigamani sees both families united and celebrating at Aagasaveeran's hotel. However, it's revealed that Aagasaveeran and Perarasi eventually get a divorce, only to reunite the very next day. Chithirai and Amarasigamani's family witnesses the couple's tumultuous relationship of reuniting despite their divorce. == Cast ==
