Who does Ryeowook believe among his members would be the harshest critic towards his pending solo debut?  He revealed as much, talking about his fellow Super Junior members during his recent showcase for 'The Little Prince.'

After revealing his teaser video, he was asked about how the members reacted to watching this. He revealed, "Yesung told me for the first time that I looked cool.  I guess I never looked that cool normally," and laughed.

"Leeteuk did say it was cool, but he also said he was not yet sure because it was just the teaser," he continued.  "He told me he would strongly congratulate me after the MV comes out."

"Who would be the most biting?" he was asked, and he picked Siwon, who is currently in the army.  He said, "[If he were to see it] he would have told me that I still had a long way to go."  Aw, that just sounds more like tough love and encouragement!  Siwon is already ready to be an Asian dad.
