Lee Guk-joo failed to hide Identity with Voice modulation
Singer Hyun-ah, Everglow Sihyun, actor Kang Han-na and gag woman Lee Guk-joo appeared on the SBS entertainment program Running Man, which aired on the afternoon of the 10th.
On the day, guests talked to the cast with Voice, which hid and altered their Identity; however, the unique huskyness of Voice, which Lee Guk-joo had, was uncovered. Yang Se-chan said, "I knew who I was!" He asked Lee Guk-joo, "Do you do the same thing with me?"
At the end of Yang Se-chan, the cast shouted, "Lee Guk-joo," and Lee Guk-joo, who was embarrassed, said, "I've never seen you here." Yoo Jae-seok asked Lee Guk-joo, "You know?" Lee Guk-joo replied, "Go back!" And made viewers laugh.
On the other hand, Running Man' is broadcast every Sunday at 5 pm.
