The best part about this manga for me is the detail that nobody bats an eyes on the fact that they're gay! Like, for example, I almost thought that those two guys will try to hit on them, but turns out they ship them
Other chapters also show that the classmates pretty much already know that they're in love besides the couple themselves. Or how Ayame's denial of her love is not because "two girls can't be together, right??" but actually because she only thought that she wanted to be just friends with her
