The supporting cast includes Vivek, Manorama and Manobala. The film's score and soundtrack were composed by Yuvan Shankar Raja. The film, which is a remake of the 2002 Malayalam film Kunjikoonan, which starred Dileep and Navya Nair as the lead couple and was also directed by Sasi Shanker, was released on 6 May 2004, receiving favourable reviews and winning three awards at the South Filmfare Awards for the performances of Surya, Jyothika and comedian Vivek, respectively.

Unmindful of his looks, Chinna goes around looking for a suitable bride with the help of his friend (Vivek). Brushing aside many an insult hurled at him, he carries on.
