They agree to love each other without meeting, and Suriya eventually moves to Madras for work.

The basic theme of the film was inspired from "Puranaanooru" literature on the relationship between King Kopperum Chozhan and poet Pisirandhaiyar, though they never met but they developed a strong relationship until their deaths. Agathiyan confirmed this in his interviews. Agathiyan initially wanted to make his directorial debut with this subject since no producer were willing to produce the film, he made few films and earned his breakthrough with Vaanmathi. Post its success, he chosen Ajith, actor from that film to play the leading role with Sivasakthi Pandian agreeing to produce the film.
Agathiyan had asked Devayani to change her glamorous on screen image for the film, and Devayani duly agreed with the film becoming the start of several other similar roles for her. The film was initially titled as Nila Odi Vaa before it was named as Kadhal Kottai.
