When asked if Super Junior is on a world tour, Ryeowook recalled his group's previous interview with 'Entertainment Relay', sharing, "To be honest, when I came on as Super Junior [last time], I hardly said anything and stayed quiet. It's not that I try to keep the mystery, but my members talk too much. I'm a hidden gem."

When Choi Jung Won was asked if there was anyone who was different from her first impression, she chose Ryeowook, saying, "I didn't know Ryeowook was this age [29]. I thought he was only 19 or 20 years old. I was surprised. I listened to him on radio, and his voice gets the message across well. I only thought of him as our nation's top idol who sings and dances well, but he is one of the hoobaes who I've started to see as an actor."

'AGATHA' will open its curtains at Hongik Art Center, Seoul on February 11!
