SEE ALSO: Jeon Hyo Sung reflects on past controversy and shares her passion for history

The idol stated, "It's a bit of an exaggeration to say that I came back from the army, but the one thing I felt about the army during my short time there was that it's an amazing place. It was very difficult. I felt so many different emotions. I realized how tough you have to be. 

She also dished on her new resolve after her experience in the army, saying, "The whole system of going to bed early and waking up early I was okay with because I like doing that, but I just had to change the way I thought and felt. Complaining about choreography practice being hard in the past seems embarrassing now. The experience taught me how hard I need to work."

A great big salute to those who volunteer to defend civilians, and a salute to Hyosung for a job well done in 'Real Men'!
