Singer Yoon Min Soo talked about Yoon Hoo's addiction to gaming. 

On the February 27 airing of MBC's 'Radio Star,' Yoon Min Soo revealed Yoon Hoo plays games all the time, and since he loves gaming so much, he told Yoon Hoo, "I don't oppose you playing games. Do it (as your profession)." However, Yoon Hoo rejected the idea and explained it's solely for leisure. 

Yoon Min Soo said, "But he plays for like 8 hours straight." To this, the MCs explained pro-gamers play for way longer than that. 

However, Yoon Min Soo said, "But what I'm saying is, I think that is what he needs to do (for life) if that's the only thing he can concentrate on for hours."
