That's right sorry^^ yes i love all H!P Kids but my favorite Kids are mostly in °C-ute^^
Maybe that's why! My girl is in Berryz, and yours is in C-ute, that's why us, the fans, think they have a rivalry when the girls don't even think about that. Anyways, both have their fan base and both groups have awesome music (even Berryz with the two ballads, if you listen to them you can see they're not that bad) :DDD
Talking about this single, I think the b-side is better than the a-side. Bishoujo Shinri has a really nice music and it's not that repetitive like Meguru. I think Bishoujo could have been a perfect a-side ><
