Great to see a new chapter of this. As much as I like this series, it feels like it should end soon, for its own sake. All characters were explored in depth, all pairings have made significant progress.
At most it deserves a big bang to go out with. Like a secret marriage ceremony (you could actually make that a mass wedding) with some sort of comic relief last boss showing up, only to be onesidedly beaten down by all the couples.
To quote a scientist: "You can be great or you can be around forever". Hopefully this series manages a proper ending and won't be dragged out until it loses all its appeal.
