I agree that diet is a grower, I hated it at first (well, tbh it was an AWFUL performance, bad singing, dancing, you name it)
But with the MVs playing while I was doing something else, it clicked. It is a "modern-sounding-berryz" for sure. It has all the previous weirdness with updated music.
And while I still find the parts before the chorus incredibly repetitive, I got immune to them, and can actually stand those parts

And the chorus and the start are awesome.
Berryz are definitely beating C-ute for me, since I believe their music has become really boring since Tokai no Hitorigurashi / Aitte Motto Zanshin
I don't think I've liked a Berryz song this much for years
