Is chapter 36 the last one? If so, then that's a rather abrupt ending, almost as if Saburouta was just waiting for this to be turned into an anime, so she could grab the money and ditch a story she was not interested in anymore.
So let's see. Mei seduces Yuzu, toys with her feelings for 8 volumes, then just turns poor Yuzu's world all pretzel-shaped by entering an arranged marriage which hadn't even been mentioned until this volume. This is SO damn cliche as to be insulting, and of course very disappointing for all the readers who were rooting for Yuzu and Mei to be together.
So, really, what was the point of all of this? Was it all just a ruse so Saburouta could cash in on having two cute girls kissing each other? Sure, I liked that, and I realize this story basically just very tastefully drawn trash, but I still feel the Yuzu-Mei pairing had a lot of potential.
Still, I can't say I am THAT surprised. I remember being extremely pissed off when Yumi and Sachiko's relationship in Maria-Sama Ga Miteru just fizzled out after some 33 volumes of teasing, but now I realize that this is just how girl-girl relationships in Japanese media get treated in general. It's all just youthful silliness, they will get married to a guy after all, and their feelings for another girl will turn into nothing but bittersweet memories.
In any case, I feel no urge anymore to keep watching the anime, since seeing Mei will only make me want to throw something at the screen. Bummer.
