"With their singing voices, hearts gently unravel. Be Girls invites listeners into a labyrinth of emotions." Featuring their signature singing voices that combine transparency and luster, along with genuine emotions expressed in the members' own words, this work contains three songs including the new track "Cadillac." Each song serves as a mirror reflecting their present, structured so that feelings true to themselves and longing for the near future intersect. A work that serves as an introduction to help listeners know the presence of Be Girls more deeply through music.
