The film begins with Varun(Jiiva) gaining admission into an engineering college, with his best friend Prakash (N. Santhanam). He and his friends one day participate in a cultural programme, where Varun finds his childhood sweetheart Nithya (Samantha Ruth Prabhu) participating in a dance show. He begins wooing her by singing on stage and later meets up with her and begins to reminisce their childhood. The film rewinds to their early days when both were aged eight, and shows the pair becoming friends after Varun had helped Nithya retrieve a book which had fallen while she had been playing. However, after a minor misunderstanding featuring Varun's brother, she decides not to meet Varun and makes a vow to never talk with him. However, the pair then meet again in their tenth standard, aged 15. Nithya initially hesitates to talk with Varun, but sheds her inhibitions once Varun breaks the ice between them, and resumes her friendship with him. Nithya is elected as a pupil leader in school and is in constant interaction with Deepak, another pupil leader and her classmate, much to the dismay of Varun. As a result, they have another fallout.
