Mano realises Jo's deep love for Prem and unites them. Mano succeeds in making Prem fall in love with Jo. Finally, Jo and Prem get married. During the story, the twists reveal that Mano had originally been in love with Jo but secretly tried to engage into her life by pretending to be in love with Nandhini. Soon after realising her true love for Prem, he sacrifices his love for her and brings Prem and Jo together. Only in the last several scenes does Jo realise Mano's love for her, but she chooses to go with Prem.
When Arun Vijay was offered to act in the film directed by S. D. Vijay Milton, he was hesitant as he was being considered by Cheran for another film, but Cheran encouraged him to accept Milton's film if he liked the story. The film was primarily shot in Ooty. Bharath, the lead actor, struggled to memorise his lines during the filming of the climax scene as Milton would frequently give him new lines at short notice.
The music of Azhagai Irukkirai Bayamai Irukkirathu was scored by Yuvan Shankar Raja and includes composing the soundtrack which was released on 25 March 2006. Milton revealed that first the scenes were shot and Yuvan composed the tunes only after watching the filmed scenes.
Malini Mannath of Chennai Online wrote that " 'Azhagai...' is a fairly engaging family entertainer, the frothy, bubbly feel-good type". Lajjavathi of Kalki felt if the director had left aside technology and graphics and given importance only to human emotions, she might have said the film is very beautiful, but now she was afraid to say that.
