MBLAQ's G.O. melted hearts with his sweet ballad on October 6th's 'Immortal Song 2'.

Clad in a suit, G.O. performed his own version of Cho Ha Moon's '80s ballad "Why Only Me", which the MBLAQ member chose himself.

Despite his amazing cover, Cha Ji Yeon moved onto the next round with 389 points. G.O. commented, "Whenever I have to perform on 'Immortal Song', I have to lessen the amount of sleep I get. I think it's because everyone's so perfect."
