Murali (Vaibhav), also known as ‘Idhayam’ Murali by his friends as he is like the emotional lead character from the film, Idhayam (1990), rings his friends, Vinoth (Vivek Prasanna) and Kishore (Arun Prasath) informing them that he is going to commit suicide, as he is not able to bear the engagement of his college mate, Madhu (Priya Bhavani Shankar), whom Murali has feelings of one-sided love. In an attempt to stop his suicide, Vinoth and Kishore request Madhu to speak badly about Murali, which Madhu does hesitantly. On hearing this, Murali feels outraged and cancels his suicide attempt. He also believes that Madhu is a bad girl. However, he blabbers about Madhu and how he loved her which slightly moves Madhu. The marriage is postponed by a year.
One year after, life moves on and Kishore invites Vinoth and Murali for his wedding. However, Vinoth is injured in an accident, so, Murali attends the marriage and also performs with his music crew, “Meyadha Maan”. Murali meets Madhu and they pick up a quarrel over a room allotment. Murali walks out of the marriage after understanding that both Vinoth and Kishore are hell bent in ensuring that he does not torture Madhu during the marriage. Madhu is pained to hear that Murali still does not know about the drama on that suicide night.
