Many different couples

This just got a TV adaptation! I watched it and it does a good job of adapting the material. I did lose interest when the main couple (Shiho couple) was removed for two arcs, but we are back to them now. The tensions in the current arc are much higher than previous ones. Personally it might have taken a bit too long to set it up before the climax volumes (36+), but overall I like how all the arcs have had happy endings.
