This Is Kathirvelan's Love) is a 2014 Indian Tamil-language romantic comedy drama film written and directed by S. R. Prabhakaran starring Udhayanidhi Stalin and Nayanthara.

Enter Kathirvelan aka Kathir, a Madurai-based minibus owner who is a devout Hindu and devotee of Lord Anjaneya since the age of five.

One day, while returning from a Sri Anjaneya temple, he sees his elder sister, Vineethra crying outside his house after his father refused to take her in, having disowned her for eloping with a Coimbatore-based mill owner Shanmugham against his wishes.

Kathir then decides to find out what caused the standoff between Vineethra and Shanmugham and leaves for Coimbatore, lying to his father that he is headed for Salem to do some work related to his minibus business.

He, however, does not return to Madurai immediately, staying back in Coimbatore after noticing Pavithra and falling in love with her, despite Vineethra's warning and his devotion to Lord Bajrangbali.

To add to Kathir's woes, Shanmugham finds out that he is in love with Pavithra, and kicks him out of his house for showing interest in his enemy's daughter.

However, while trying to tell Kathir's father about Pavithra, Mayil consumes poison and is immediately rushed to the hospital, which it is later revealed that Mayil pretended to poison himself by pretending to swallow laxatives, fearing the wrath of Kathir's father, and thereby revealing the identity of the person in the prologue.

This film doesn't work because it's hard to empathize with any of the characters and the actors fail to rise above the flawed script".
