BTW, sensei announced in advance that volume 6 will be a thicker volume, so there might still be at least 2 chapters left.
On the last page of last month's YuriHime, there's no "climax chapter" indication for KimiTsuzu, so I'm leaning toward 2.
But yes ... it surely going to come to a conclusion sooner than later.
There are 2. The next month's chapter is the final.
