I told him, 'My son is making a movie, and I would like for you to compose the film's music.' But he never asked me, how much will you pay me. But I told him, 'I know how much you earn these days, but I won't be able to match your salary. I will try to pay you how much ever I can,'" said Karunaas.

The actor added, "He told me, I don't want you to pay me anything. For you and Ken I will do this for free.'" Karunaas mentioned that he will always be thankful for this gesture.
