Kathir mentioned that he dreamt of a "beautiful place full of young people" and was inspired by College Road in Chennai, with a setting by the beach which formed as "opening visual idea" for the film. Karunakaran, who became a successful director in Telugu cinema started his career as clap assistant with this film. Then struggling actor Vikram had dubbed his voice for Abbas, while Baahubali-famed dubbing artist Sekar dubbed the voice for Vineeth. Tabu was signed on to make her debut in Tamil films and worked on the film alongside Mani Ratnam's Iruvar. Vineeth was signed on to play another lead role in the film due to his association with Kunjumon, having previously worked in the 1993 Shankar-directed film, Gentleman. Kunjumon asking him to come over for a screen test as a result of Kathir's insistence. A year later, Abbas received a call from producer K. Initially reluctant due to his limited knowledge of Tamil, he opted out and left for his college in Mumbai. Mumbai model Abbas was enjoying his holidays in Bangalore during his holidays and hanging out at a cybercafe near Brigade Road, when he bumped into director Kathir, who asked him to act in his Tamil film. He narrated a five-minute plot summary to Kunjumon who was impressed with it and insisted Kathir to change the film's title to Kadhal Desam instead of its original title Kalloori Saalai.

Kathir while writing the script "wanted some drama rather than plain love and so wrote a story of warring colleges and two boys in them". Hence the film ends with Arun and Karthik regaining their friendship. At the end, Divya says that she likes them both but does not want to choose one, thereby losing the other and disrupting their friendship.
