He was outed a being gay, and was gossiped about and smeared by his community, and was alone. It's not like he created the hell himself.
That's... Not a thing he could do. Please remember that Japanese culture is very much about not making waves, and it prioritizes harmony over individuality (not a bad thing, just a different thing). Telling them off would have been very weird in that culture, especially since it was also a small town, and they were also his customers.
Add to this his own self-loathing and rather passive nature, and it probably just didn't even occur to him to call them out, and it's probably for the best that he didn't; it would only end up increasing his ostracism and would hurt his livelihood.
I'm speaking from personal experience here when I say that there are situations where you just can't tell people off. As a gay man myself, I've learned that sometimes I need to bite my tongue instead of call people out, because, y'know, safety and politeness and context and all that.
Tl;dr, logically he could have told them off, but actions don't exist in a vacuum, and the social consequences meant that he actually couldn't.
i do get that, i know as much about Japanese culture , also my future art project will be about the dead cuteness and suicide cases in japan, back to our character, they already knew about him, there was nothing like : i don't want them to know about me, it was a matter of telling them to just accept it, the mangaka drew them in a kind of unsuitable shape, as if to say he takes their shit and the heavy weight of it , which hurts me so much, i never said what he did is wrong, i just said i *wished* if he broke away from them, cuz yes he will get hurt but at least he did all he could
i like the 1st story, but i wish that stupid stage where he sits to watch ppl will be smashed !it's a metaphor to his loneliness, a hell he made him self so i though that at least the end of the story will have him break it...
and the 2nd story is also really sad which made me like it, this is the 3ed time i read it ><

edit: when i said a hell he made him self, i meant when he never put off those whom ashamed his sexuality , tho that never hurt them, i never said he or they were right and never even thought about making a comment about smt so oblivious as how society fucked him up, also , yes he helped making that hell with them, or else we would never even have needed the other character *the seme?* , to change his view about him self...
