Yep I literally said in chapter 6 that it may get axed, and it got axed in 13 chapters. Next chapter is ending.
What a shame, author simply couldnt handle the premise. The idea was good, having 7 yandere harem was interesting but since protag was only running away from them and he literally never let protag met any of them (he only met a single character in 2 years of publish) everyone lost interest in it, hence got axed with only a single volume.
I doubt author will get any more serialization after this, while art is great unfortunately he suck very much at writing and pacing.
Basically just like the comment above said, had a cool concept but horrible execution. Should have included one heroine per time and let them adapt to the modern world & get a relationship with protag and other heroines while carrying the yandere aspect even if its suppressed.
A very big shame, I was very interested in the first chapter and thought I'd definitely buy this as it continues, but now definitely not buying at all.
