Yes, there is a comment by Erina Mano. It's not a surprise to us since she's in the thumbnail. How much of a surprise it is to the members… well, that's up for debate.
(overreacting to things is part of the job. literally. they're coached on when and how to do it.)
Tsukiyo should have been an a-side instead of Kanashimi ga Tomarenai but that's just MY opinion. This song is what I wanted from the single and I'm properly irritated it's relegated to being a b-side. At the least they posted a dance video to it so people can listen to the song.
Tsukiyo no Pas de Deux was very good. It took me back to the same feeling of Machigai Ja nai. I'm glad we got a Dance Version. Otherwise I wouldn't have known the song and dance were this good.
I can't believe this is a Double Cover single since both Original Bsides are much better.
