They put this chapter together with chapter 31 in the anime, which gives a different impression of what is going on.
In the anime she only cares about the student council,
Here she has a debt to repay.
There's also the cake and Ishigami's back ground being removed from adaptation.
this chapter here fits better than it was shown in anime with an earlier chapter. seriously i would have liked to see hayasaka' suffering chapter instead of this chapter in anime.
I think it would be Ishigami's loss because he's still being tormented by Kaguya.
Page 18: "That's just the way Shinomiya is. She can't lie to herself." Looks back on the multiple volumes of both her and you lying to yourselves about your feelings. You sure about that?
