☆The song features LOONA's own concept that no girl group can replace. It subtly mixes softness and dynamics, and takes this month's girl to the next level with new beats, drop, electronic sounds and melodies that have never been heard in K-Pop.
It conveys a message that "You are LOONA, too" if you are encouraged, find yourself, and make a voice through LOONA's music by a butterfly effect called "LOONA".
Digipedi, the visual director of LOONA, toured five countries by continent for the butterfly effect of LOONA, capturing the courage and freedom of girls around the world in the music video for the title song "Butterfly."
