How will the school react?

There Is no significative progression yet.
I mean, Nagatoro and Senpai are still embarrasing at the bare notion of a relationship between the two of them.

I'm a huge nagafag and such, but agree with those who say that it's been a while without important scenes since the Art's festival

Technically a good number of them saw an art gallery entirely dedicated to her
It shouldn't surprise anyone

The entire arc following the art festival was pure concentrated progression
Sure they still DON'T fuck like animals in the art room, which is a real shame, but their behavior towards one another really evolves quickly these days
Just compare how they were before and during the art festival and how they are these last chapters, they've grow closer in every last one of them
Will it lead to more blue balling or will it lead to actual physical affection between them, who knows
But I really don't think its stale at all

it was like 30 chapters ago

Prez will give Sakura an art lesson and when she directs her from behind her boobs press against Sakura's back.

and then they kiss just as Gamo, Yoshi, Naga and Senpai barge in
nice

Sakura is for nerds club gangbangs only.

Sakura is a poor confused girl who seduced boys because she felt that was what she was supposed to do but is now realizing that yuri is the purest form of love

There was some pretty significant progression during the zoo chapters where they essentially stated their love for each other by how much effort they dedicated to drawing each other. Including the scene of paisen standing up for naga's drawings.

>poor confused girl
What a joke, Sakura is the biggest semen demon.
