Raja is a college student who is popular among the other students. Subhadra, his sincere and quiet classmate, never speaks openly even with her closest friend Lavanya. Subhadra's father had deserted her mother and two daughters, suspecting that she had loved someone before marriage. As a result, people in their locality look down on Subhadra's mother, who supports her children by stitching clothes and is the subject of most gossip sessions. However, Subhadra concentrates only on studies without getting distracted by other issues as advised by her mother, and maintains a safe distance from other college boys.

Subhadra's male classmates Madhu, Kannan and Thambu tease her in class by narrating the rumours about her mother and gossip about her love for Raja. When she gets upset, Raja tries to protect her from Madhu's group many times. Raja and Subhadra develop fondness and miss each other if they do not see even for a day, though they never speak to each other about the good feeling they have for each other. Raja's classmate Moorthy notices Raja's interest in Subhadra. Lavanya also notices the same affinity in Subhadra towards Raja.

One day, when Raja expresses his love to Subhadra, she becomes angry and rejects his proposal. Though she actually likes him, due to her family situation and mother's instructions to avoid men, she shows no feelings for him. Upset, Raja declares he will never speak to her about his love again; he confidently states that she will come to express her love for him one day. Their silent love continues within themselves.

Raja eventually falls ill due to liver jaundice and does not attend college. When Lavanya visits him, she learns of his deep love for Subhadra and the suffering he is going through. Lavanya meets Subhadra and shouts at her cowardice to express her love to Raja. The academic year ends. Subhadra's mother learns about Subhadra's love and insults her. Subhadra now decides to meet Raja to express her love as she no longer wishes to hide it. Though his health has worsened, Raja comes with Moorthy by train to college to recollect their college days. Subhadra sees Raja seated in the train and expresses her love, but is devastated upon learning that he is already dead.
