Yeah and I think this would work a lot better if it just made it the premise initially or part of a gag, but as is it feels so contrived. Like the MC just happened to watch anime and got too invested so he learned skills in literally everything that'd normally make him the most popular man in the world? Like ya'll have mandatory gym and changing and I'm supposed to believe no guy's seen how ripped he is and told everyone else? None of the class saw how strong he is? The worst part is the MC not realizing this. He just comes off as an ignorant dumbass.
A series where the MC is a super elite because of anime and knows it so he's an open Otaku but no one can criticize him with a comedy routine and the gal love interest would be a great subversion of the genre. Currently though I can't even tell if this is supposed to be rhetorical. The author is either a bad writer because they can't write a rhetorical gag Manga clearly or a bad writer because they can't write a realistic entry in a basic genre copying a million other existing series.
I've enjoyed this series so far. My bias comes from being burned out on other otaku MCs who are always shying away, being neurotic, or always playing the straight-man.
I do agree on your point about how there's no way he doesn't get seen at school (my only theory being that he wears an undershirt, and that's a super weak argument). But at the same time, applying to much logic to a manga comedy makes reading more annoying than enjoyable.
The dense mindset has been done to death, but in my opinion, it feels different from the usual kind. Going against what I just said about logic, if I were randomly approached by a hot chick, I'd questioned alot things, even if I have general confidence in myself.
I believe the author is writing a story that more optimistic than most, and it probably won't be for everyone.
The only thing left for me to say now, this MC felt boobs on his back, and just went, "fuck it, I'll carry everyone" instead of being overly conscious about it. I've never since this instance portrayed in any other manga. Props~
