Kandhakottai(2009)

Siva (Nakul) is a nice guy who doesn't believe in the concept of love. True to his hatred, he also doesn't hesitate to go and break up love birds. Pooja (Poorna) on the other hand believes strongly in the force of love and does whatever she can to ensure that lovers get united. The story takes a turn when Siva's sister falls in love with Pooja's cousin. As expected, Siva tries to break the couple while Pooja unites them. Finally, Siva gives up and at the same time, he develops feelings for Pooja. What happens from there forms the rest of the story.
