I've never really been one to like these mother/daughter themes, but this one is a definite exception--- and by that, I mean it's exceptional. Can't wait for it resume
I was subbed to their pixiv for a while and checked out some of their stuff on the Japanese Amazon, and from what it looks like, the mangaka is redoing the whole thing. Which is to say, there isn't a second part yet, and at this rate I don't know how long it'll be before this story picks up from where it left off. If it ever does.
