In mid-November 2016, Chakri Toleti began working on his fourth feature film, following the bilingual Unnaipol Oruvan (2009) and Billa 2 (2012). Nayanthara was selected to play the leading role, and it was revealed that the film would be a heroine-centric project.[7][8] A first look poster was subsequently released on 18 November 2016, coinciding with Nayanthara's birthday, with it being revealed that the film would mark the first production of venture of musician Yuvan Shankar Raja and the first Tamil film production for Pooja Entertainments' Vashu Bhagnani and Deepshikha Deshmukh. Later, Yuvan Shankar Raja and the other producers opted out of the project. V. Mathiyalagan of Etcetera Entertainment took over the production of the film. Tamannaah Bhatia is reprising Nayanthara's role in Hindi remake titled Khamoshi, which released on June 14, 2019.[9][10]

The film was scheduled to release in India on 14 June 2019, but was delayed because the film shares its name with a novel by Sujatha, which director Balaji K. Kumar paid ₹10 lakh (equivalent to ₹12 lakh or US$16,000 in 2023) for the novel's rights. The plea for the film is held on June 21.[11] The film then went through multiple release date changes, eventually releasing on 9 August.[12][13]
