I'm assuming we'll get side stories bc it was quite successful, but typically the authors and artists take a few months break between the end of the series and side series, just like in between seasons. The creators spent years on this, I don't think it's that they couldn't be bothered..
Did they really intended for this end this way? it felt kinda abrupt especially their escape past the wall, and the whole government stuff, i dunno kinda feels theres still a lot unresolved stuff, especially with hohyun being the cure and all
Was this story not popular or profitable? Could be the only reason why this was not prolonged, or that creator just couldnt be bothered any longer
