On November 17 episode of KBS' television show 'Problem Child in House', Jung Yong Hwa and his fellow band members Lee Jung Shin and Kang Min Hyuk made a guest appearance.
As it had not been long since they all completed their military service, they were asked a lot about their life in the military.

Kang Min Hyuk said, "Well, when I was in the military, our agency debuted Cherry Bullet. So, I used to promote them a lot."
He continued, "The most popular groups at our base were BLACKPINK and ITZY though. The soldiers would go crazy over them."
Lee Jung Shin said, "It was a little different for us. There was this 'IU Storm' at our base. We all had IU's songs as our mobile alarm."

He resumed, "Out of all of us there, one senior officer was the only one who had a phone with him. He happened to have 'DALLA DALLA' by ITZY in his phone."
He went on, "We asked him if he could play the song, but he kept saying no, because he wasn't allowed to use the phone beside for an emergency use."
He laughingly added, "But he ended up playing it for us as we kept pleading him. We slept while singing along to 'DALLA DALLA' on that day."
