Actor Ji Hyun Woo has caught the girl group obsession that male soldiers catch during their two-year army service. He also revealed SECRET to be the most popular girl group among soldiers.

On the February 27th broadcast of YTN's 'Issue And People', Ji Hyun Woo appeared as a guest along with his co-stars from the army musical 'The Promise', Kim Moo Yeol and Leeteuk.

Ji Hyun Woo revealed how soldiers become obsessed with girl groups after entering the army, sharing, "The girl group that is currently the most popular among soldiers is SECRET. When I do military work in Wonju, all of the soldiers stop what they're doing when SECRET comes on screen. When I wake up, I watch music shows, and before I go to sleep, I watch music shows. I want to watch dramas, but they all watch music shows."

Ji Hyun Woo also praised 'The Promise', saying, "Even when compared to other musicals, the production quality is outstanding. The adults who watch the musical say, 'It would be nice to show this kind of meaningful musical to middle and high school students.' I want to show this musical to students who are currently enrolled in school."

Let's hope Ji Hyun Woo's girlfriend Yoo In Na doesn't get jelly of his love of girl groups!
