Since apparently I'm cursed and any series I really like and and scanlate is usually doomed, here's my rundown:
- The long hiatus is usually not a good sign.
- Manga will not just end suddenly (unless for special reasons), when a series ends they almost always announce it in the chapter before that, so we're getting at least 2 more chapters.
- While it's not a concrete indication, but Shoujo Nyuumon was the 4th last series in the magazine (in terms of publication order). I don't know how it exactly works for Comic Flapper, but usually in the case of magazines the more unpopular series get put in the back.
- Volume 1 had 173 pages of content, 23 of those being new content. The page count for the future Volume 2 right now is at 102. That leaves us with about 70 pages. The last chapters have all been either 16 or 18 pages, so with 3 chapters it would put it at around 150-156 pages, with still extra pages to spare for bonus content.
As much as I want it any other way, it's not looking that great. But if the series is indeed ending, my best guess is that there's going to be 3 more chapters until there's enough to fill a new Volume.
