As you may or may not have heard, the artist has had to drop out for health reasons (you may have noticed that they missed a bunch of months a while ago). Hence the little "The End" and "Thanks for reading" on the last page. This was only announced a couple days ago, and apparently the fate of the manga is still being decided, but I'd say there's a good chance it will resume eventually with a different artist and possibly a different name. Since it's an official series, it'd be odd to leave it hanging there.
This has happened before, when the first artist of the Three Fairies manga had to drop out for similar reasons and was replaced a couple months later.
Anyhow, wishing a quick recovery to both the artist and the manga.
