Kumarasamy aka Kumar (Thagar Bachan) is a poor man who lives in the same village and is the classmate of Kokila.
Vetri clears civil services and comes back to village with plans of marrying Kokila in a registrar office.
But Kokila refuses getting married without her family's consent and requests Vetri to meet her parents once with the hope that they would agree as he is well educated now.
Vetri gets furious that Kokila didn't turn up at the time of his visit and also worries due to his father's death.
Kumar describes the pathetic state of their old school in village and requests them to take some action to prevent it from getting shut.
But Vetri is not interested to return to the village as he has been humiliated by Kokila's family members long time ago.
The event successfully happens and everyone feels happy that the school is saved as many alumni donate for renovation works.
