On the October 22nd airing of "Yoo Hee Yeol's Sketchbook", Super Junior's Ryeowook and Beige held a collaboration stage singing, "Falling in Love with a Friend" and "Insomnia". During the interview session, Beige remarked, "I had held a strong relationship with Super Junior. We bonded as I became a fixed guest on their radio shows. Leeteuk is a matchmaker, he even gave me Ryeowook's number!" Ryeowook replied, "I'm happy to sing with a pretty nuna like Beige. It's completely different from performing with Super Junior." During their performance of "Falling in Love with a Friend", Ryeowoo actually took hold of Beige's hand, attracting attention from netizens and viewers alike. Was it just a friendly stage act, or do you think that the two are on their way to becoming a couple? In the meantime, check out the performances below!
