So many people get flashbanged by the eroticism that the fact that the gimmick is executed upon perfectly slips past them. Personally, I've found the "insights" truly unique so far (I'd have never expected anybody to compare panties to onigiri, nor expound upon the appeal of holes in gym pants), and frankly, even though I'd like for her to engage in yuri at some point, that point doesn't have to come for another 20 chapters. They can take their time. I'm really interested to see what enlightening knowledge will come out of this font of wisdom next.
And if I might say, I love the proportions of these girls. Plenty of busty cuties all around. Doubly glad one of them happens to be the protagonist.
