Mounaragam

Kalyani is now a young woman. Though mute, she is talented and intelligent, but still longs for her father's affection. When she was small, Kalyani had saved the life of a rich boy named Kiran. After a long gap, Kiran tries to find out who the girl was. He meets Kalyani and immediately likes her kind, calm nature. He decides to employ her as a cook in his construction company. Eventually they both fall for each other. Kiran then abandons his fiancée (and cousin) Sarayu. Kiran does not know that Kalyani is mute and thinks that she is on a Maun Vrat (a fast of silence). Kalyani decides to reveal the truth to him. Kiran is shocked, but ultimately forgives her and decides to encourage her to become confident and bold. Heartbroken that Kiran has left her, Sarayu becomes jealous of Kalyani and vows revenge on her. Sarayu's parents, Rahul and Shari, support her in this.

Kalyani's brother, Vikram, is a cunning, spoiled brat and falls for Sonia, a wealthy girl who is revealed to be Kiran's sister. Vikram discovers Sonia's wealthy status and attempts to make her fall in love with him, but fails. Vikram then discovers that Sonia is an art-lover. Since Vikram does not know how to draw, he requests Kalyani to draw a picture for Sonia. Kalyani does this without knowing the reason. Vikram gives the picture to Sonia and tells her that he drew it. Sonia is then attracted to Vikram and they grow close. Sonia becomes pregnant with Vikram's baby. When she tells this to Vikram, he rebuffs her. Sonia attempts suicide, only to be saved by Kalyani. Prakashan does not want this marriage to happen because Sonia's uncle, Rahul, is Prakashan's enemy. Rahul is also against this marriage due to his enmity towards Prakashan. So Prakashan demands that on the eve of the wedding day, Rahul must wash Prakashan's feet, or the marriage will not happen. This infuriates Rahul and he decides to kill Vikram, who is saved by Kiran. He protects Vikram from Rahul's goons for the sake of his sister. Rahul then plans to marry Sonia off to a meek man, Baiju, so that no one will question Rahul's authority. Kiran and Sonia object to this. Meanwhile, Vikram is thought to be missing, which horrifies Prakashan. He tries his best to find him, but fails. Sonia and Baiju's marriage is fixed, and Kiran promises Sonia that he will bring Vikram to the ceremony. Indeed, Vikram arrives on time and marries Sonia, foiling Rahul's plan. Kiran and Sonia do not know yet that Vikram had pretended to know how to draw so that rich Sonia may fall for him. After marrying Sonia, Vikram manages to open an interior design department in Kiran's company, and keeps using fraudulent methods to conceal that he is not an artist.

Kiran introduces Sonia to Kalyani, and both girls get along well. Sonia supports Kalyani in facing her problems. In order to ruin Kalyani's life, Rahul, Vikram and Ratheesh (Kadhambari's husband) team up and hire Baiju to marry Kalyani, much to Kalyani's and Kiran's dismay. Prakashan accepts this marriage proposal, as he had always wanted Kalyani to be married off to any unsuitable groom. Prakashan had earlier been planning to marry her off to Rajappan, a loan shark who lent money to Prakashan. Sarayu and her mother, Shari, rejoice that Kiran would now marry Sarayu instead of Kalyani. Kiran and Sonia try their best to prevent Kalyani and Baiju's marriage from happening. Meanwhile, Kiran and Sonia's niece, Paru, enters Kalyani's life. She stands by Kalyani's and quarrels with people who pester Kalyani, which leads to hilarious events.

Paru taunts Prakashan by calling him Kaduva (tiger) and calls Prakashan's mother Moonga Muthassi (owl grandmother). She also hates Sarayu and calls her Ettukaali (spider). Paru expresses that she wishes Kalyani to marry Kiran, and helps to arrange their wedding in 'Thevar Kaavu'. But, in order to separate Kalyani from Kiran, Rahul reveals that Kalyani drew the pictures for Vikram and that Vikram is not an artist. Kiran becomes angry at Vikram and also at Kalyani. Kalyani and Kiran part ways, and the ceremony is cancelled. Kalyani starts working at the company's construction site to avoid meeting Kiran. But Kiran soon realizes that Kalyani wasn't the real culprit and that Vikram duped her for his own benefit. Kiran tries to talk with Kalyani but she refuses, since Kiran's mother (Roopa) has told her to stay away from Kiran. On the other hand, Kiran quarrels with Vikram for betraying his sister but manages to keep it a secret from Sonia.

Kiran's love for Kalyani grows and he seeks ways to help her. He prohibits her from going to the construction site, as he could not see her working as a daily wage laborer. But Kalyani and her friend Lindaa misunderstand this, and Lindaa advises Kalyani to be stronger than before. Kalyani is hired at a small restaurant, where she cooks food and helps the old lady owner. Kiran arranges for Kalyani to get a job as an interior designer in a reputed company called Sony Ray. Because of this, the interior design department of Vikram's company becomes backlogged as Kalyani's company gets more work than Vikram's. Kalyani earns a good salary, buys a diamond necklace, and even receives a two-wheeler as gift from her company (which was actually gifted by Kiran). Kalyani's lifestyle changes much, but she still remembers Kiran though she never tries to meet him. Prakashan is infuriated by her changed lifestyle and tries to torture her again, but she is bolder now with the support of Sonia and Paru. She is well-accepted by her co-workers and is loved by the staff because of her intelligence and kindness. Once Baiju comes to flirt with Kalyani. Enraged, she assaults him. Baiju realises that he cannot marry Kalyani and decides to treat her as a friend from then on.

Meanwhile, Shari and Rahul inform Roopa about Vikram's true colors. Shocked, Roopa faints and is rushed to the hospital where Rahul lies to her that Kalyani was drawing pictures to help Vikram trap Sonia. This intensifies Roopa's hostility towards Kalyani. Vikram is in a fix as his company is suffering loss and is shut down. He is obligated to celebrate Sonia's birthday by throwing a huge party, but he is in dire need of money. He approaches Sonia's family, who reject his request, while Kiran and Roopa taunt him. But Kalyani lends Prakashan money for the party via his friend, and this is revealed later in the party, due to which Prakashan storms out from the event. Meanwhile, Roopa decides to fix marriage between Kiran and Sarayu, but both Kalyani and Kiran are sad on knowing this. On the eve of the wedding, Sarayu gets chickenpox. In spite of this, Roopa tries to fix their marriage, without telling Kiran and Sonia about Sarayu's illness. On the other hand, Paru leaves for an important surgery and Roopa tells everything to Kalyani, who feels helpless. However, Kiran finds out the secret planning and asks Roopa about it, which ends in a heated argument. Kiran then storms out of his home and meets with an accident due to driving at a high speed. Roopa realizes her mistake. She agrees for marriage between Kalyani and Kiran, much to the dismay of Rahul, Shari, and mainly Sarayu. Sarayu puts up an act before Roopa and Kiran that she has changed and is ready to marry someone else. She shares her plan with her father and he contacts Raj Mohan, a criminal. Kiran is excited to marry Kalyani, but is worried if Roopa would discover Kalyani's disability. Meanwhile, Sarayu sends Anas to kill Kalyani.

Kiran reveals to Roopa that Kalyani was the one who had saved Kiran's life in the childhood incident. Roopa starts liking Kalyani even more. Roopa fixes their wedding and gives her ancestral ornaments to Kalyani as a gift. Shari is enraged and opposes the marriage. Even though angered by Roopa's actions, Rahul and Sarayu act nice in front of Roopa and Kiran and support the marriage. On the other hand, Prakashan becomes jealous as Kalyani is going to marry Kiran and argues with her. Rahul and Sarayu try to ruin Kalyani's marriage. Kiran arranges a job for Prakashan on Kalyani's request for which he gets rupees 1 lakh as advance, but Prakashan is enraged when he sees Kalyani. The owner of the company files a complaint against him. Prakashan threatens revenge on Kalyani and Kiran.

Prakashan sneaks into Kiran's house and removes the brakes from his car. The next morning, as Kalyani and Kiran are about to go out of the house, Roopa stops them from entering the car, saying that the car is giving some problem and has to be taken for repair. After they leave, Roopa calls Vikram to take the car to the repair centre. Unfortunately, Vikram suffers a serious accident while driving the car. The doctor reveals to Prakashan that Vikram has lost his voice as the seat belt injured him. This infuriates Prakashan. He lashes out at Kiran, who is visiting Vikram at the hospital, and blames him for the accident. Meanwhile, the matter is unknown to the family and Kalyani suspects something is amiss. The truth is soon revealed, shattering all. Prakashan blames Kalyani for the accident and beats her up. An enraged Kiran blackmails Prakashan by showing him the footage of Prakashan sneaking into his house and removing the brakes. Prakashan begs Kiran not to reveal the truth. Kiran agrees on the condition that Prakashan be nice to Kalyani. Prakashan agrees to it, but has something else in mind.

Trying to divert Kalyani's mind from the unfortunate incident, Kiran arranges for her to travel to Kanyakumari for a project along with a staff member. Kiran plans a surprise for Kalyani by travelling to Kanyakumari along with Baiju and Paru. However, Sarayu finds out and hires an assassin to murder Kalyani. Kiran surprises Kalyani and organizes a party. Kiran is called by an anonymous number warning him that Kalyani's life is in danger. Scared and anxious, Kiran tries to protect Kalyani. However, the assassin enters Kalyani's room and tries to murder her, but Kiran and Baiju save her and thrash the assassin, who reveals that Sarayu was behind all this. Kiran is shocked.

Later, Sonia enters labor and is rushed to the hospital by Kalyani and an unknown man, who is revealed to be Chandrasenan, Kiran's estranged father. Chandrasenan and Roopa had split due to some issues and Rahul had supposedly killed Chandrasenan, but he was rescued by people. Rahul and Shari are doubtful whether Chandrasenan is alive or not.Chandrasenan reveals the truth to about his real identity shocking Kalyani and decides not to reveal to the truth. Sonia gives birth to a baby girl after Chandrasenan saves her by donating his blood. Prakashan does not accept the baby, but his mother has changed her ways and is happy with the child. Vikram pretends to be joyous and is loving towards the child. During the Noolukettu ceremony of the child, Roopa invites Chandrasenan, and Kiran and Sonia wish to invite Kalyani, but Roopa tells them not to because Sarayu had revealed to her that Kalyani is mute from birth. Roopa develops instant hate for her because of her disability and because she had lied to her about her silence-fasting. Kiran threatens Prakashan to invite Kalyani or he will show the footage to everyone. Prakashan agrees meekly and talks with Roopa.Then later Cs with an old man look comes along with Kalyani to Nooluktu ceremony. The Cs plans marriage for Kalyani

Kiran and Sonia finds out about his real father and reunites with him. Even Baiju and Paru find Kiran's Father and they embrace him. One day Prakashan suggests that Kalyani should marry CS's son. Deepa resists his idea and he assaults her. CS incites Deepa against Prakashan's tyranny and she takes a bold stand in front of Prakashan. Eventually Roopa also comes up with the same idea, and CS agrees to a plan to have Kiran marry Kalyani instead. Kalyani, Kiran and Deepa also agrees to the plan. But they fear that if Roopa doesn't agree to the wedding. Roopa is elated and gifts Kalyani 101 gold sovereigns, much to Sarayu's dismay. Sarayu mixes the real jewelry with fake jewelry so that Deepa and Kalyani will be arrested if they ever try to mortgage it. Kiran becomes aware of her plan and switches the bags again so that Deepa gets the original one. Sarayu decides to mortgage the jewelry (which is actually fake) and is arrested by the police. Roopa is angry at her for bringing shame upon the family repeatedly. Kiran and Kalyani get engaged in presence of Chandrasenan and Deepa

Finally the wedding day dawns. Prakashan's family, Rahul, Shari and Roopa are happy that Kalyani is marrying Cs's son. Kiran puts up an act that he is having chest pain to divert Roopa's attention because Cs's friend Sooryakumar is bridegroom in front of Roopa's family and Chandrasenan is bridegroom in front of Prakshan's family and Roopa doesn't like to see Chandrasenan.
