Palak Jain says it's funny to play Avika Gor's little sister when in reality, she is elder to the Balika Vadhu actor. "This [age difference] was the first thing we spoke about. I asked Avika, 'How do I call you didi? You are four-five years younger to me. It is funny. She looks elder to me though in Laado - Veerpur Ki Mardaani," says Jain.
