When asked about an older brother in real life, D.O. said, "He is three years older than me. Memories of playing with him and fighting with him helped me in this movie."  The interviewer then asked, "How was working with Jo Jung Suk? People say you guys look alike." D.O. replied, "I am just thankful. I was his fan, so I've watched all of his previous works. I always wanted to work with him, but I didn't know I would meet him so soon. I liked that he was like an older brother, and I am thankful that he led me while filming."

Then, D.O. was asked about his fellow EXO members. The interviewer asked, "Do you talk to them about your acting career?" and D.O. shared, "They monitor my work for me. The members and I share a common denominator of doing acting and music simultaneously. They don't tell me what to do, but they cheer me on. Recently, I enjoyed the drama Baekhyun was in. When he was doing a romantic scene, it was a little cringe-worthy, but I endured it watched it. I'm sure the members feel the same way about my acting," while laughing.
