This was published on Hirari #13, the Hirari magazine ended on the #14 issue. I haven't read it yet, but Fumie's listed on the cover as one of the authors in that issue, so the second chapter of this was probably in it.
Still, with hirari dead, I'm guessing we won't see a third chapter of this.
That might help explain why the ending just feels a tad rushed. The thing about not really having enough space / time to complete what you were trying to accomplish, but also not wanting to leave your readers hanging without any conclusion at all. Would have been nice to see at least one or two more chapters.
Still, I really like Fumie's work, and this one is no exception: sweet, but including the trademark light drama undertones.
