Expanded Chronological Narrative Ending:

The film reaches its conclusion with each of the three couples facing a pivotal moment that brings clarity and resolution to their respective conflicts.

First, Rangesh and Pavithra's story reaches its turning point when Rangesh, after losing his job and confronting his own insecurities, breaks down in front of Mithra, the marriage counselor. He confesses that his dissatisfaction with his life and his harsh treatment of Pavithra stemmed from his own unfulfilled dreams and the pressure he felt from his family. Pavithra, who has been working out and regaining her self-confidence, listens to his confession and realizes that his behavior was not just about her, but about his own struggles. She does not excuse his actions, but she chooses to forgive him and work on their relationship. Rangesh apologizes sincerely, and the two begin to rebuild their marriage with a new understanding of each other's needs and vulnerabilities. Pavithra continues to focus on her own well-being, and Rangesh supports her efforts, showing a marked change in his attitude.

Next, Arjun and Divya's story reaches its climax when Arjun finally acknowledges his insecurity and the way his ego has damaged their relationship. Divya, who has been subjected to emotional abuse and constant correction from Arjun, opens up about her feelings of being disrespected and undervalued. Arjun, after a series of counseling sessions with Mithra, realizes that his need to dominate and control Divya has been the root of their problems. He admits his mistakes and asks Divya for a chance to make things right. Divya, though hesitant at first, sees the sincerity in Arjun's apology and agrees to give their marriage another try. The two begin to communicate more openly, and Arjun starts to respect Divya's intelligence and independence. Divya, in turn, feels more valued and supported, and their relationship begins to heal.

Finally, Mithra and Manohar's story reaches its resolution when Manohar discovers a bag full of notes that Mithra has written, expressing her true feelings and emotions. These notes reveal that Mithra has been struggling to express herself honestly in their marriage, often hiding her anger and frustration to keep Manohar happy. Manohar, upon reading the notes, realizes that Mithra's actions have not been manipulative, but rather a reflection of her difficulty in being open about her feelings. He confronts her about this, and Mithra finally opens up about her struggles. The two have a heartfelt conversation, and Manohar expresses his understanding and support. Mithra, in turn, promises to be more honest and authentic in their relationship. The couple reconciles, and their marriage is strengthened by their newfound honesty and communication.

In the final scenes, each couple is shown in a state of renewed connection and understanding. Rangesh and Pavithra are seen supporting each other, with Rangesh encouraging Pavithra's fitness journey and Pavithra appreciating Rangesh's efforts to change. Arjun and Divya are shown working together, with Arjun respecting Divya's opinions and Divya feeling more confident in her role as a partner. Mithra and Manohar are seen sharing a quiet moment, with Mithra expressing her feelings openly and Manohar listening with empathy and understanding.

The film ends with a sense of hope and renewal, emphasizing the importance of communication, honesty, and mutual support in maintaining healthy relationships. Each character's journey highlights the challenges and rewards of working through marital conflicts, and the film ultimately suggests that with effort and understanding, even the most troubled relationships can be salvaged and strengthened.

Rangesh becomes unhappy and dissatisfied with himself and his marriage, particularly reacting negatively to Pavithra's weight gain after marriage and pregnancy. He exhibits misogynistic behavior, including wanting a divorce and making Pavithra feel miserable, such as complaining about her bad breath. His core issue stems from personal trauma and discouragement from pursuing his dreams, which he eventually reveals to the counselor Mithra, leading to a complex emotional arc in their relationship.

Arjun feels insecure about his masculine dominance when Divya demonstrates strong intellectual ability. This insecurity causes him to correct her for even minor mistakes, creating tension. Eventually, Arjun admits his mistake and asks Divya for a chance to reconcile, which leads to them patching up their relationship.

Mithra is a psychologist and marriage counselor who becomes the main connector between the parallel stories of the couples Divya-Arjun and Pavithra-Rangesh. She uses her counseling techniques to help these couples navigate their marital issues, while simultaneously facing challenges in her own marriage with Manohar.

Mithra's marriage with Manohar faces strain as she becomes more honest about her feelings, including rage she had disguised to make him happy. Manohar confronts her about this behavior, putting their relationship on the rocks. Mithra attempts to reconcile using her counseling techniques but eventually snaps and fights with him, highlighting the complexity and emotional turbulence in their relationship.

The counseling techniques are central to the narrative, as Mithra applies them both professionally and personally. They serve as tools for the couples to understand and address their issues, though sometimes the application leads to conflict, especially in Mithra's own marriage. The film uses these techniques to realistically portray the fragilities of marriage and the importance of communication in resolving conflicts.
