"(...) manga will reach its climax in the magazine's next issue on October 17."
Climax means last chapter/end of the manga..
In storytelling, climaxes are usually followed with a falling action and resolution. I honestly would have assumed at least a few more chapters, so the manga would end with 8 volumes at a decent pace, but then again I wouldn’t be surprised if we went straight to the epilogue next chapter. I’m hoping that’s not the case, since the characters are finally all on the same page with one another, and there hasn’t been any resolution for the side couples either.
