i just noticed, why is there a hand in the prez painting? look at page two. did he literally just copy paste the picture from last chapter and made it into a small version?
The reaction of the prez resembles nagatoro's whenever she is jealous. Same dark aura on her panel... maybe she does like him and didnt like the idea of him having a kouhai harem while she is away studying
Lets see the positive here, up to this point. She thought that he was only seeing her as a way to lose his virginity. She now knows that's not the case, so the plot partly has moved forward.
