I really like the c/w.
It's not a song I think I'll get the urge to listen to a lot, but it seems like a song that makes the mood better when it's on in the background or something.
I'm kind of impressed with the way everyone sounds too, they were all nice to listen to. On top of that it seems Haruna can avoid talk-singing as much now, I can add another instance of enjoying Riho's voice to my list, and I got to hear Kanon and Haruka actually sing something. Thumbs up for me.
