[talk] Daesung's self-management class is really professional

I was surprised at how strict the abstinence from alcohol was for three days before the schedule.
It's so cool to hear that he quit drinking to sing well.

It's great that you say that the joy is greater when you do well without making excuses.

Even though he likes drinking, he is serious about his work, so I think that's why he quits drinking so much.
