Her previous appearance on 'Sponge Zero' was then dug up. In the screen capture below, she shows off her bare face on the left and then her transformation after putting on makeup on the right side. She said jokingly on the show, "I participated because they said they would do my makeup prettily, but I was tricked," to everyone's amusement.

In relation to this, Woori turned to Twitter to address fans once again on February 6, "Can't you please forget about 'Sponge' now?" and uploaded another picture of herself with no makeup.�
