On the September 20 airing of 'Song Eun Yi and Kim Sook's Unnies' Radio', Hyorin revealed, "I'm working on self-composed songs. There are many songs that haven't been revealed yet. I might not use them if they don't turn out well."
The DJs asked if anyone asked her for songs, and Hyorin answered, "The Cultwo members asked me in the past. Recently, Soyu asked me to give her a song if there's one that fits her well. I don't have one yet so I told her I will make one."
