Talk:ES Idol Song Season 1: Eden/Lyrics/@comment-44162481-20200830094429

What does the "(Nagisa↓)" "(Hiyori↑)"mean tho, i mean whats up with the down and up arrows? does it just shows that hiyori singing high notes and nagisa singing low notes? Also, why is there a "nagisa" and "eden" it's just confusing for me.

despite all of that this song slaps H A R D
