LMAO, that moment was Izumi moment and its immediate aftermath were as funny as they were glorious.
Returning back to jovewolf's comment, it's interesting how Iroha was affected, but Akio is unaffected.
TBH, what with a lack of a reaction on Akio's part on Izumi's moment and with the fact that he's in an all-boys school, I wouldn't be surprised if he's gay or bi or pan or something.
Fujishiro will probably have an explosion of jealousy, a jealousy I predict is gonna end up being poorly-grounded, but necessary for the Fujishiro-Kurokawa relationship development. For Fujishiro to realize that her feelings for Kurokawa are love and for her to convince Kurokawa that she isn't lesser than her, so they could finally get into a romantic relationship.
I also hope the manga doesn't just end when they do enter that relationship.
