Omg, please tell me half those couples did not kiss for the first time OFF-SCREEN. Like...I get that that's the original kind of manga this was, but...if it happened now, it would totally kill the tension that's been building up between them! Especially Nononon and Yumimi, whose whole thing has revolved around that...
That said, I loved Mayuyu's jealous moment- maybe they're starting to become more aware of their feelings (though I suspect Mariri already kind of is). I'm hoping that (all of it, really) wasn't another off-screen relationship upgrade like Haruka and Kanae. I know Ayano and Miyoshi kissed a lot early on, so I'm hoping it's just a 'girls kissing girls' kind of chapter, but the manga hasn't really been going in that direction recently, so...
If not, that was a great chapter! If so...super disappointing.
