An actor from Goddess is Watching talks about Ryeowook:
When I knew Ryeowook was a member of Super Junior, my first thought was "So he's an idol." and thought they will not participate in practices often.
I have many idol friends so I know the type of schedules they have. For Ryeowook hyung's case, he just released an album so time should be tight. But he will still take time to come practice for 1-2 hours. I feel that it is really amazing. My impression of him has also changed alot, his schedules should be more tiring than what we imagined but he still faces everything with a smile.
