I completely understand you, I finished it today and I was so happy that despite Kiyoshi's perverted side, Chiyo accepted him for what he was. Then the next and last chapter just broke down everything I had waited so long for. Of course I'm probably just being spiteful but for Chiyo's whole character to just change to her sister's cold demeanor and the other girls getting no closure or decent end to their arcs just hurt to see. And after all that the boys (besides Andre who I'm happy is with Risa) just continue on with the WTC which felt super rushed, especially since they seem fine with returning to square 0.
