Kundan Shankar (Dhanush) is the only son of Tamil Hindu Brahmin parents settled in Varanasi. While collecting donations at his teacher's house for Dussehra when he was a child, he sees Zoya (Sonam Kapoor), a Muslim girl, praying in the adjacent room. He immediately falls in love with her and for years would attempt to talk to her or flirt with her, while not even knowing her name. Zoya slaps him multiple times, before getting quite fond of him and finally telling him her name. She asks him to meet her in private, and when they do she finds out that Kundan is from a Hindu Brahmin family. She starts to avoid him on purpose as her family is very orthodox, and she knows for sure that her relationship with Kundan would go nowhere. Zoya's family figures out that she likes a Hindu boy, and decide to send her away to Aligarh for further studies. After she leaves, Kundan tries to get on her family's good side by helping them with chores around their house. Zoya gets into Jawaharlal Nehru University, Delhi and starts making new friends, falling for student leader Akram Zaidi (Abhay Deol).
