Tamizh, a visually-impaired singer, performs at a wedding and crosses paths with Sudhanthirakodi, nicknamed Kodi. He teases her as part of their playful dynamic, which unsettles her and prompts her to walk away with the newlywed couple's gift. This first encounter plants the seeds of both friction and attraction.

The following day, Tamizh meets Kodi again on a train, and his friend suggests a misdirection to make her miss her stop. The prank sets off a chain of complications that threaten Kodi's first day of teaching practice. The moment marks the start of their complicated relationship.

Kodi and her friends pursue the person who tricked her, determined to undo the mischief. The chase threads through the city as they try to fix the unintended consequences. This pursuit deepens the bond among them, setting the stage for future interactions.

On another train, Tamizh casually reveals to a friend that they played the prank on Kodi, not realizing she is nearby. Kodi responds by striking him with her walking stick, leaving him bleeding and stunned. The moment crystallizes their volatile dynamic but also foreshadows changing feelings.

Tamizh feels embarrassed by the incident, and his friends tease him about it. Kodi, recognizing her misstep, apologizes when they next meet. Their awkward reconciliation softens the initial hostility between them.

As they spend more time together, their friendship grows deeper and Tamizh begins to fall in love with Kodi. He starts to see her beyond the playful teasing and the initial friction. The relationship transitions from friendship to romance.

Tamizh writes a heartfelt romantic poem for Kodi and records it on a CD to preserve his message. The gesture becomes a tangible expression of his growing love. He envisions Kodi hearing his feelings.

When Tamizh visits Kodi at her school, he slips the CD into her bag as a quiet confession. Later, Kodi's best friend reveals that Kodi longs to marry someone who can see, revealing a barrier to her happiness. This revelation complicates Tamizh's hopes.

Vinod, the volunteer reader at the service center, invites Kodi to lunch and seems poised to propose. He introduces his fiancée instead, leaving Kodi heartbroken and realizing she cannot count on him. This moment deepens her longing for someone who can truly see them.

Kodi discovers Tamizh's CD and is moved by his devotion. Tamizh then endures a difficult search to find Kodi's favorite clock that contains her late father's voice as the alarm, a keepsake she cherishes. The hunt strengthens his resolve and her feelings.

Kodi's elder brother arranges a forced marriage for her in exchange for a favor, forcing Kodi and Tamizh to consider eloping. They decide to run away together rather than submit to the brother's terms. The escape highlights the obstacles posed by family and greed.

Tamizh manages to gather enough money to pay off Kodi's brother, but corrupt policemen trick him and he falls into a trap. He is knocked down by an oncoming van in the ensuing chaos. The incident creates a dangerous setback for their plans.

Unknown to Tamizh, Kodi is also in the same van headed toward the same destination. The two travel in complete silence, unaware that the other passenger is the love they seek. The moment underscores the distance between them even as they move closer physically.

After Tamizh recovers, he learns Kodi has left Chennai to stay away from her brother's family. A reporter friend informs him that Kodi has been spotted in Mumbai, prompting him to travel there. The lovers are finally united in Mumbai, completing their journey together.
