Ishqbaaaz actor Surbhi Chandna says her on-screen husband, Nakuul Mehta, has been her biggest support system on set. "We have shared an amazing bond since the beginning of our project. The show has been running for over a year, and our equation has got better. Nakuul has been my biggest support system; he helped me understand the industry’s dynamics. I cannot thank him enough," says Chandna.
