Meanwhile, a series of events forces Krishna's close friend Aravindh (Karthik Kumar) to come to India from the USA to get married. His parents arrange his wedding with Ramya. Ramya, who decides to get married to help her younger sister's love, displays herself as a passive character who accepts whatever the life partner feel is right. On the contrary, she is bold, active, independent and assertive in nature. Knowing this, Krishna tries hard to let her true character come out. However, Aravindh stalls the wedding plans and returns to the USA as he finds Ramya as a person who does not think on her own and not independent. Mistaking Krishna for influencing Aravindh, Ramya locks horns with him.
