You realize that this is a manga about her and her teacher understanding each other and get together right? And don't clump the goat Aoki with that shit of a human being, Aoki is always supportive not because of morbid senses but because he is genuinely nice and trying to help with the best he could
Those two are getting annoying as fuck, the series would be better if it was just Kokonoe and Aoki with the struggle of their relationship with some shenanigans here and there, but Kuro and Usa are annoying, especially that lesbian piece of shit
Are you stupid or what
There is no "technically" or any "something-rape" that you and your people made up
She didn't force him to do anything and only did what a person with a responsibility of another should do, Reiji is the one who made the made the move
The icky thing shouldn't be the age difference because this is fiction, but the facr that Koyuki is just a rapist who take advantage of vulnerable people, she's not an ideal partner
