If you read the other comments on this page (and there aren't that many LMAO), you can see a pattern.Last chapter shouldn't have END attached. It's in the middle of the story and last page says to be continued. So definitely not the last chapter.
Dude it is the worst when series that are actually starting off STRONG get axed
Here, the scanlators didn't drop it, but the stupid company dropped it.
Yes, chapter 17 really is the last official chapter, though the author clearly intended it to continue, as you noted.Even easier to forget since it was discontinued at chapter 17.
