After revealing weeks ago that 2NE1 leader CL visited the emergency room during a recording of 'Yoo Hee Yeol's Sketchbook,' the special episode finally aired in Korea on May 23 with the theme: using music to console people who were having a difficult time, especially in light of the tragic Sewol ferry accident.

The group, for the first time ever, performed the unplugged version of their last title track, "Come Back Home." �The girls wore all black and pinned the yellow ribbon, symbolic of hope during the tragedy, onto their chest as they lent their voices to this moving rendition.
