Super Junior Leeteuk revealed his workaholism.

On the July 7th episode of KBS 2TV Talk Show "Do Dream", Leeteuk appeared and confessed his concerns about his being a workaholic.

"I start to get anxious when I'm not working. I don't know what I should be doing on the days when I don't have anything on my schedule. When I am just lying on the bed doing nothing, I even get tears. When I asked people around me, they all told me that I must be addicted to work."

He went on to add, "I don't even know how to have fun anymore. I thought I was trying to keep in touch with people around me but now I look around me and there's no one left." He said that the other Super Junior members just felt like family because they were together so much but he doesn't have very many friends outside of the group.

He also told stories about when he visited Saipan on vacation.

He had just finished his first tour and came back to the hotel but he started to be overcome with thoughts about what time it would be in Korea and how his absence made him nervous. He did get a timely call from Lee Seung Gi and he flew right back to Korea, which surprised everyone on the show. 

He also revealed his weekly schedule, which was packed with places to go Monday through Saturday. 

Fans reacted to it, expressing regret over his workaholism and wished him recovery, saying that he should ease up on the schedule and learn to have fun with people around him.
