I kind of hope it goes something like Senpai telling her that her attitude is "gross" and just walks away, leaving her to get all fired up. Too out of character for him maybe.
I hope we get back to silly situations like the Oni mask in the main chapters. The current arc and pacing are great but after I hope we see more of them being cute together.
There's a lot going on. Yamada's "payback" on the bed for Ichi seeing the Milk Tea (which Ichi gave her), Yamama in nylons.
Then there's Yamadad, seeing this little emo boy leaving his apartment building wearing his daughters gym clothes.
