Heechul congratulated Junhyung on his birthday, "Happy Birthday, Yong Yong Yong Junhyung. As a present, Kun Hee and I sang a congratulatory song together and left a pitiful memory as we blew out the candles."

Junhyung's birthday couldn't have come at a better time as he recently made his solo debut with "Flower" and celebrated another successful year with an intimate birthday party.

Happy Birthday, Junhyung!
