They said, "Two songs included are ballads, and both of them talk about the pain of farewell.  Everybody goes through separation, so if they can understand that, they can understand these songs, too."

Sojung then confessed, "It was really not easy when we were recording.  It was extremely hard.  As a result, I think there were more emotions put into it than in our first and second albums . . . If two people were having a hard time, then the other person [out of three] would put in more energy, and the like.  If someone looks to be having a hard time, we would do things like say 'Fighting' more brightly on purpose."
