Kyuhyun, who is currently promoting as a solo artist, appeared on SBS radio program, 'Cultwo Show,' on November 24 and mentioned his older sister (noona).

One listener stated, "At a hangout in a neighborhood, I witnessed a friend eating with his older sister.  I had thought it was his girlfriend, but he emphasized it was his sister."

Kyuhyun revealed he had gone through the same experience in which people saw him eating with his sister and mistook her as his girlfriend.  Kyuhyun said, "There's a restaurant I frequent with my older sister.  Because my sister is pretty, people kept looking over.  I purposely said, 'Noona, do you want to order more?' and kept talking about our mom," making everyone laugh.

As his older sister played the violin for over twenty years, the two had even collaborated onKBS's 'Immortal Song' in the past.  She had even appeared on KBS 2TV's 'Superman is Back' to teach Tablo's daughter, Haru, the violin!
