Ook JooHyun is a female singer and musical theater actress. She performed in “CATS” with Daesung in 2008. She played Grizabella, while Daesung played Rum Tum Tugger (photo below for reference). While this picture was posted today, there is no word on exactly when it was taken (though based on Daesung’s hair color, it was recent since the hair is black).
