Rihito saying he gets it when Noa started talking about how amazing friendship is caught me off gaurd. With how annoyed he seems each chapter, I genuinely forget that he canonically enjoys being friends with her.
Yep. All of the times he's actually content are skipped over, like in the middle of a game of Splatoon or when Noa's obsessive nature targets something mundane, since it's not interesting enough to be in the manga.
I mean yeah, compared to everyone else on this series. Like he is a genuine guy who just happened to have an overprotective sister with clingy co-worker/best friend.
