New still-cuts from the upcoming KBS 2TV drama 'Prime Minister and I' depict YoonA's transformation into a cleaning lady!  

It appears that YoonA is truly a passionate reporter who would do anything to get an exclusive scoop, yet she is not without errors and mistakes that hinder her from achieving what she wants.

In the pictures above, she appears to have infiltrated as a cleaning lady, wearing the full uniform and holding a mop.  However, she seem to have been caught as it looks like the security is dragging her away.  

Make sure you watch what happens once the drama starts airing after 'The Future Choice' on December 9!
