The flagbearers did the flag part instead of singing because they didn't have any solos or big duet lines. Lol. It's very simple. Why complain about them not singing when they barely sang in the song anyway?
Meanwhile: the Haruna/Miki duet line slays me every time. Their voices sound so cool together.
Also super proud of Erina/Kaedi's two solos in the second verse. They've gotten so good.
Because 2 of the 4 girls are pretty much invisible in this single and those duo lines are pretty much the only interisting thing they got ?
