Pretty sure you did not see a "fin" or "end" then the story still goes on.....
Yeah i mean that as if its like a promo for a novel and they stop the manga serialisation at a point where the readers even if they don't continue by picking up the novel they still get a somewhat competent short story
( like with " as the villainess i will keep the final boss" the manga and anime ended at the end of the first big arc and didn't publish the full story)
it doesn't end at chapter 6. currently, it has 9 translated chapters on the scanlator's website ヾ(❀╹◡╹)ﾉ~
Sad if yes but then again that would make the story short and sweet and just right for quick in-between
