Yaazhan (Dulquer) and Mouna (Aditi Rao Hydari) are a young, urban upper-class couple. Also, more importantly, their characters in this film seem like they are from a Mani Ratnam love story. The leads of this film Dulquer Salmaan and Aditi Rao Hydari, have played leads in two separate relationship dramas of Ratnam. Brinda, who makes her debut as a filmmaker with Hey Sinamika, has choreographed many songs for Ratnam.

The Mani Ratnam connection is not just in the title.

The title of this film, as you probably know already, is borrowed from O Kadhal Kanmani, a Mani Ratnam romance.
