Okay, this is hysterically funny. How come I had never heard of this manga before???
The teacher in chapter 6, rather than a character, is an avatar for pretty much every yuri fan in this forum. I think I recognized all her lines as comments I have read here, in some thread or other. :P
Before I read a dozen chapters of this, are there actual couples depicted or this one of those series with a large set of characters who just generally act gay (for lack of a better way of describing it)?
