Well what else did you expect? Them to end the manga on an actually good, well planned and paced ending? This is a SoL, Harem, school life story. That kind of shit only ends in one of 4 ways.
1) Axed
2) Infinite hiatus
3) Sloppily made ending which either has an open ended kind of ending, a kiss, or a massive time skip to just 3-5 pages of life after all of the plot development the author didn't write has happened.
4) It just doesn't, and you just get repeated plot line after repeated plot line until either the magazine goes under, or the author dies/gives up. (i.e. milk the fuck out of it until there is literally nothing left to salvage even a decent ending with)
We are currently sitting around a 3.5 at the moment if I had to guess. Author plans to milk the series until there is just a smidge left to hastily end it in a way that leaves the reader feeling robbed of a proper ending, ok enough to not cause a major issue.
