Super Junior's Yesung laid down the law on the November 24th installment of 'Under Nineteen'.
He continued, "I know this team likes dance normally, but you're doing this because you want to be a singer. That means you have to know how to have basic singing skills. If they're people who perform on stage, you can't joke around in the practice room. You can't when you bring a lyrics sheet, and when you get it wrong, you have to do it with confidence. It's a nuisance if you don't."
Yesung also discussed his trainee days, saying, "The debut team has only 9 spots. When I was a trainee, there were about 80 trainees in all, and only 12 could debut. I really risked my life. For a few months, I didn't say a word to my members because I was in a risky spot. I really put everything into it. Only the people who really want it can debut. From my perspective, you don't want it that much. When a good opportunity like this comes, you need to risk your life on it. The only thing you can do is risk your life on it."
