Adding more, he said about his character who is suffering from post-traumatic stress disorder, which is a mental health condition that is triggered by a terrifying event and may lead to nightmares or severe anxiety. Rao said: "I already know, you know, some people who are suffering from different sorts of mental illness, not precisely to be PTSD. But I saw a lot of reference videos, I saw a couple of interviews of patients online, just to understand what happens, why it happens, and what it does to your body, physically and mentally?"
