'Dream High 2' producers are keeping two characters a secret.

In the still cut released, only Kang So Ra and Jung Ji Woon are turned around to show their faces. The sexy backs of Hyo Rin and Ji Yeon can be traced back to the two girls, but the two other guy characters are still a mystery.

The two men with stylish clothing and long legs are really raising the curiosity and the anticipation of the viewers.

The two unknown characters will be revealed at the first press conference.

About the photo an associate of the new drama stated "'Dream High 2' will not only feature idols and popular actors of today but also talented rookies."

First broadcast of 'Dream High2' will take place on January 30th.
