Casting
V. Thiruselvam had some casting choices for the female lead, but B. Srinivasan preferred to cast a film artist for the female lead as he had already informed Sun TV.
Actress Soundarya was first approached to do the female lead. Although she was interested, she was unable to join the crew due to her 2-years contract with the Bharatiya Janata Party to support them during election campaign.[5] Then Devayani was suggested for the female lead by the production side to the director to which he had agreed as she would perfectly fit into the character and she was already acting in films. Initially Devayani had some issues over the terms and conditions agreement with the production side, as a result she almost opted out of this series.
As a result of even considering Kousalya to do the female lead from the production side. But, Sathyapriya who was signed to play the mother of the female lead (Abinaya) managed to convince Devayani to play the female lead in this series and sorted out the misunderstanding between her and the production side. Apart from such issues, Devayani was very interested after listening to the script from her husband Rajakumaran to whom the director had already narrated and he had also praised the director. So, she signed to play the female lead Abinaya.[6][7][8][9][10][11] Devayani made her acting debut in television with this series.[12] Actress & Dubbing artist Deepa Venkat who is very well known for playing supporting roles in many serials & movies & lead roles in few serials was signed to play the female lead Usha.
