The trailer for Once More is out, offering a closer look at the film's emotional core — a young man, played by Arjun Das, struggling to find closure from a past relationship, even as Aditi Shankar's character tries to win his love. The film explores themes of second chances, healing and the weight of unresolved feelings. Sona Olickal plays one of the two love interests of Arjun's character, with Devadarshini and Dravid Selvam also part of the cast.

Directed by debutant Vignesh Srikanth, the film features music by Hesham Abdul Wahab — known for Hridayam and Hi Nanna — in his Tamil debut. The song Vaa Kannamma has already gained traction online ahead of the August 28 worldwide release. The film is produced by Yuvaraj Ganesan under Million Dollar Studios.
