Cho Yi Hyun noted that she had to practice physically for her role in "All of Us Are Dead." "I trained for about three months, and it was quite difficult," she said. I'm a little athletic, but the director was concerned about my stamina. Choi Nam Ra grows stronger in the second half of the drama, and she is the only character capable of defeating Yoon Gwi Nam (Yoo In Soo). Even though it's a technique that relies on momentum rather than strength, slinging Gwi Nam over my shoulder was challenging. I gained some physical strength during the filming period since I'm stubborn. My stunt double was also quite helpful."

Cho Yi Hyun said she needed more concentrate for a scene with On Jo at the end when asked if there was any scenario where she had to utilize more energy or pay closer attention (Park Ji Hu). "It's near the finish when I'm going to bite On Jo," she explained. It's a moment in which I'm alone in a fight with her, fighting not to bite her. 'Don't come,' she yells. You were warned not to come! ' Nam Ra vanishes. When I first imagined that moment, I imagined myself at a loss for words and unsure of how to act. That was my final day of filming, and because everything I'd done up to that point had passed through my mind, I was fully engrossed in it. It's also my favorite sequence in the movie. After being in groups with a lot of friends, it's a scene where it's just the two of them, and filming with Ji Hu felt really comfortable."

Cho Yi Hyun later revealed that she auditioned for "All of Us Are Dead" without understanding what type of film she was auditioning for. "At first, I auditioned for the character of On Jo, which is played by Park Ji Hu, and [director Lee Jae Gyu] requested that I perform more brightly," she explained. 'This is my brightest right now,' I remarked, and he inquired, 'Are you normally this calm?' 'I'm not sure,' I admitted. Because it's difficult to describe myself personally,' I assumed I had failed the audition."

When asked if the web claims that she was born in the city of Gwangmyeong and was a gymnast were real, Cho Yi Hyun said that they were not. She then went on to describe how she studied the arts in high school and practiced for many hours. "No, I was born in Seoul," she explained. "Perhaps they're wrong about me practicing gymnastics since I'm flexible," she smiled before saying, "I don't even know how to do gymnastics." I was a member of the musical department in high school. Because I couldn't dance, sing, or act, I had to study everything thoroughly. I practiced dance for six hours a day on weekends, so my physique grew a little more flexible. Sometimes, I do flying yoga on days I’m not filming.”

Cho Yi Hyun commented on how she was disappointed by the times she failed auditions in her early acting career. She mentioned that shifting her mindset helped her gain confidence. "At first, I was discouraged," she added. Then, one day, while I was leaving for an audition, I remembered this. 'I'm about to fail again,' I thought. I'll put in the effort and return after I fail again.' I finally let go, and the audition went well. Since then, I've decided that facing a situation in a similar state would be preferable to being mindful of doing well. In comparison to my contemporaries or others with similar job experience, I believe I am less apprehensive during auditions."

She went on to say that she tries her hardest and avoids being greedy. "I work hard on what I'm ordered to do," she added. "I've failed innumerable auditions, and if I'm lucky enough to pass, I'll give it my all." 'All of Us Are Dead' was a hit after living each day like that. With the passage of time, I believe I am becoming less greedy. More excellent things have happened as a result of this."

Cho Yi Hyun defined herself in a single line at the end of the interview when asked what kind of person she is. "Cho Yi Hyun is a person who works hard in life today as well," she remarked.
