I am, I'll admit, a bit dense when it comes to flirting; not "MC DENSE," but I'm a little unaware.
I'm also polyamorous, which actually leads to way more unwanted flirting than you could ever imagine (the phrase "im good, thanks," just doesnt seem to register to people when you have more than one chubby on your arm...).
But after 100 chapters, and over a year of in-universe time, this dumbest can't figure out that "I want to date you" means that they want to date you?
I have known kids in Special Ed that had this shit figured out before this MC; it’s unrealistic to believe that he can talk while walking, or that he can breathe and think at the same time, because he is just too fucking stupid.
It's lazy writing, and makes me think the actual print form of this manga would be used as toilet paper, except I'd worry about making my ass too stupid to poop.
