We have to hand it to Leeteuk—stretching his acting muscles in a musical, and an army musical at that, is definitely an impressive side project for the Super Junior star.  The cast of the The Promise performed the second act before a group of reporters today.  After the insider preview, the cast spoke, at which time Leeteuk revealed, “I will do my best so people will say, ‘Of course, that is Super Junior’s Leeteuk.’”  Fine.  Fair enough. Are you going to catch Leetuk in his third musical?
