So, someone just speculating online.
Was this axed?
Most of the time, we can never know. Authors and publishers usually don't go out of their way to advertise "axed" vs. "was intended to be this short" vs. "author cutting it short for personal reasons."
Very rarely, an author will gripe about untold story; I think Gal and Villainess was one such, maybe Sal Jiang's Wicked Spot too. If there's public talk of low sales and pleas to support the title, that might be an indicator (though some claim that's just uninformative marketing tactics.)
If an author seems to introduce plotlines that suddenly get cut, or set things up that don't pay off, like Usio Shio's doll-licker story, that's suggestive. Though Usui lost two titles at once, so either she had really bad luck or she bailed out of making manga for reasons of her own.
Probably 95 if not 99% talk of "axed" is just fans trying to make sense of something they liked ending, with no real information.
