Okay, I finished this little series and it's. It's bad.
It seems like she got too ambitious and had this awesome premise with one of the best heroines she's written but then beefs it totally. From chapter 10 on the story accelerates faster and faster to the end that you practically get whiplash. And then you crash, and as you pull yourself out of the wreckage you realize it was for nothing, because nothing whatsoever was explained.
I actually like Ueda's romance, but this one was so bad I actually think fans of her should skip it.
