Kwanghee accordingly revealed a photo of himself at the army training center. In Mar. 21, the Korean Army Training Center reportedly posted a picture of Kwanghee and other trainees who were allegedly admitted into the army in Mar. 13. Contrary to his usual bright and friendly image, he is seen sporting his army uniform and proudly saluting together with his fellow trainees.

According to Soompi, Kwanghee was formally admitted into the Nonsan Army Training Center and will do grounding for five weeks before going on to serve in the military band. Prior to his enlistment, his fellow "Infinite Challenge" gave him a farewell video as a send-off.

"Youngest of 'Infinite Challenge' Kwanghee! You've worked hard during the past two years," was the "Infinite Challenge" staff post on their official social media account. They also wished him a safe return after completing his military service.

Kwanghee accordingly entered the military training alone. Purportedly, his only words to some of the press waiting for him at the location was that he will come back healthy and well. "Please stay healthy and do not forget about me," he reportedly added.

Kwanghee is reportedly ever the cheerful guy as he prepares for his military service. In Mar. 12 episode of MBC's "Section TV" he was portrayed discussing a potential replacement for him on the popular variety show "Infinite Challenge." When accordingly asked who he might recommend taking his place, he looked a bit unhappy that someone will soon replace him.

According to Mydramalist, he is a member of the nine-member boyband ZE:A managed by Star Empire Entertainment. They debuted on Jan. 2010 with the single "Mazeltov." In May 28, Kwanghee attended the "2011 Environment Day" event in Seoul, where he participated in clothes layering game. He accordingly shocked everyone by putting on 252 layers of t-shirts, earning him a Guinness World Record for the most T-shirts worn.
