I still can't rationalize the girls' mindset of Jun being this asshole for not getting flustered and treating Tomo like a normal girl. I know this is a comedy, but comedy has to follow some form of logic. Even absurdist/surreal comedy pokes fun at what's considered logic and this manga is far from being absurdist/surreal (this isn't Bobobo-bo Bo-bobo). The entire point of the manga so far was for Tomo to get Jun to treat her like a woman, and now that Jun is seeing Tomo as a woman the guy is considered a jerk by Tomo and her friends. I guess its a "damned if you do, damned if you don't" kind of hypocrisy here.
