Hahaha, worst confession ever.
I'm glad I wasn't the only one that thought Mada should've just thought (or said): well, let's get rid of Kousaka.
Yes, everything happened as it should and the author handled it well. The only problem is that this means that we won't have much more Saki in Nidaime, which is bad. Just by showing up the manga gets far better.
Also, the manga lacks a character like her. She was a normal person in a group of otaku. That was fundamental in the first generation. Now there's just tons of fujoshi and the only different one is Hato, and not different enough, because despite teh fact taht he's a guy, he acts just like a tsundere fujoshi. And he is closer to fit Kousaka's role (being an otaku that looks good) than Saki's.
If only there was, I don't know, a yuri fangirl or a relevant male character that created some sort of conflict with the girls. Maybe another guy that didn't look like an otaku but in a different way, like a tough guy iwth a strong personality...
