It really reads like your typical rom-com where there is shit load of misunderstandings and main character has like no agency over his own life.
Dude is basically treated like air, people either do shit without a single thought about what MC wants/feels, or they watch what happens around him like its some kinda TV drama. All the girls have barely 2 functioning brain cells, they basically ruin his life slowly, put him in bad light/situations, and thats even when they know they fucked up and just want to apologise or something.
Yet if you ignore all the gags/stupid stuff and just concentrate on MC - instead of a kinda dense typical rom-com MC, we get a dude that basically out-right told his sister, that she should wait till high-school ends before he goes off-line with his life - aka suicidal dude, that from like primary school has his life fucked over by betraying class-mates, idiotic girls or even adults, idiotic mom that didn't care for him at all, sister that told him to die cause she was jealous of a friend, etc. Like normal people would be already dead after suicide, or moved to a different fucking planet, or at least become kinda cynical and tell everyone to fuck off like the dude in Nyanta to pomeko.
As long as this MC is kinda cynical, he is unable to tell people to fuck off, and goes out of his way even risking his life to help the girls that ruined his life - so theres a difference.
