On April 30th, singer IU guested on KBS's "National Heroes" and helped gagman Lee Soo Geun complete his jump roping mission. After first receiving the mission from the producers, Lee Soo Geun began circling the area to find a female celebrity to complete his mission with.� As if on cue, IU popped out into the hall after finishing her radio schedule and readily agreed to join him despite being completely bare faced and unready for the camera. Viewers thought that she looked a lot more friendly without being all dolled up and expressed their interest in her girl-next-door charm.�Some commented, "IU still looks beautiful", and "Such a cute bare face. I'd love a little sister like her!" Source: TV Daily via Nate
