This manga just impresses the hell out of me.
It was already good when it was self-published, but all we really saw then were scenes between Urumin and Kimiya at and after concerts. But then when it got serialized, instead of just redoing the existing chapters, the mangaka took the opportunity to basically start all over and flesh it out, and it's so much better.
It's especially neat that we've learned why and how it is that the rest of the group tolerates her clumsiness. And it's made it so that instead of Kimiya being inexplicably obsessed with this idol with no apparent redeeming qualities, it's Kimiya recognizing, just as her friends, fellow idols and family do, how adorable she really is underneath that awkward exterior.
Good stuff.
