Like the statement says in that movie: "What We've Got Here Is Failure To Communicate." Seriously, if Class Rep could have only expressed her feelings willingly before all this took place, Tomosaka would have had no cause or need to try out the so-called hypnotizing app. And then, from a certain panel on page 24, one may indeed wonder whether that app worked at all.
Thanks for the upload. I've yet to read the doujin, but regarding the title fuuki iinchou is the Morals Committee Chairman, not the class rep. (see https://ouo.io/DmjDb0 )
