I think I found two glitches? (I'm playing through on the mean path where I chose not to help Iris. )
When finishing with the first meeting of the 4 girls in the school lunchroom, they want to feed you before they go to class and they refer to Iris' video. MC then says a line about how he only did that because she was sick, however, being on the rough path, I never encountered that scene. I was treated to being woken up and forcibly used instead.
Also later once you get home Iris apologizes for the whipping, which I don't remember receiving either.
