Kwak Hyun Hwa, the rookie who successfully transformed from a gag-woman to a singer, showed off her talented singing skills on the radio. On August 12th, the singer made a guest appearance on the SBS radio show 2 o'clock Escape Cult Two Show, and powerfully sung her debut song, Psycho, live. This is the first time Kwak Hyun Hwa has had to sing on a radio live without any elaborate performance. Regarding singing live on the radio, Kwak Hyun Hwa commented, "I feel so nervous. It is a different kind of nervousness from appearing on a television music program. I wanted to do really really well so I practiced all night. I hope everyone looks at me positively."
