Sana Sayyad on her role and shows comparison to Raazi said, "While the story is about an undercover agent, it has nothing to do with Raazi or even Ek Tha Tiger. With our show, we want to pay tribute to the many unnamed detectives, who are no less than soldiers for us. Sejal's flaws make her different. Honestly, I have always wanted to play a RAW agent or a spy and I feel I manifested this project."[7][8]

The story was nice and so were the cast and the production house. In fact, even the ratings were decent as compared to other shows on the channel. I think there are more shows in the offing. They might come come up with a 2.0 and I would love to take it up if it's the same team."[4][28]
