^Or maybe they just looked at the ratings? Hmm? This manga has the lowest on their pixiv
Well, maybe. Some physical magazine use ratings to decide what to keep doing, so maybe YH is doing that for Pixiv. It's rare to axe something with one volume, but maybe they hate a minimal rating to achieve.
We'll never know unless the author speaks up about it, though (and not sure if someone cares enough to keep an eye on them).
