Production
The lyrics of the song were written by Madhan Karky, whose work won critical acclaim even prior to the release of the audio. He went on to explain that the term "Kuviyamilla" featured in the song meant "out of focus" in Tamil and it reflected the occupation of the lead character in the film, who plays a photo journalist. The song was sung by a leading bass guitar player in Chennai, Aalap Raju, who initially believed Harris Jayaraj had called him just to play the guitar for the song. The song was predominantly sung by him, whilst Prashanthini, Sricharan and Emcee Jesz also performed back vocals with the latter singing English lyrics. The song appears in the film featuring Ashwin (played by Jiiva) singing the tune as well as through montage scenes. The song depicts the character's love for Renuka (Karthika Nair), whilst Saro (Piaa Bajpai) shows affection for him. The song was shot in regions in Norway as well as across Chennai.

Release
The song was released as a part of the soundtrack album which was launched on 12 January 2011, at the Image Auditorium in Chennai, with the presence of the film's cast and crew, and other celebrities, which was followed by a press meet the following day, at the Green Park Hotel in Chennai. The audio event was telecasted on Kalaignar TV on 26 January 2011, coinciding with Republic Day.

The teaser trailer's success prompted the media to claim that the audio soundtrack to the film was "red hot" with reports indicating the pull of the particular song.
