Former After School member Yoo So Young will be reuniting with leader Kahi, as it's just been revealed that she was cast in 'Dream High 2'! Earlier, we reported that Kahi was cast as one of the school's teachers, but Yoo So Young will be playing the role of a student, making their reunion one of a teacher and student. News of her casting had netizens buzzing with whether they'll be rivals, but representatives were quick to put them down, stating, "Kahi is a teacher and Yoo So Young is a student so there will be no rivalry in the drama." This will be her second acting project since her departure from After School back in 2009. Since then, she's acted in KBS's 'Women of Our Home'.
