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."
The actor then revealed the snorer as Dynamic Duo member Choiza. "There's no way around it. You just have to sleep before he does," commenting on Choiza's loud snores.
