Which hip hop artist's snoring kept Lee Dong Wook awake during his military service?

He said,"There was a time when I was in the military and had trouble sleeping because one of the soldiers, who happened to be a hip-hop duo member was snoring."

Lee Dong Wook went on,"He was a junior, so he slept next to me. I couldn't take it anymore, so I tried blocking out the noise by covering my ears with a pillow. I even tried leveling his neck in a certain position, hoping the snoring would subside."
