Ugh... this volume really dropped the ball. Maybe manga was a mistake.
The Kayo/Suzu plot is actually my favourite plot in the series because it's less boring than the Senri/Chiru stuff (even though they're the main characters). And the Kayo/Suzu plot is still the best part of this volume. But the problem is that the darn sideplot with Momo having a crush on her teacher turned from a waste of page space to genuinely uncomfortable as it seems like the teacher likes her back. And Momo is fucking nine years old!! Teacher, go directly to jail, do not pass go, do not collect $200! This sucks, man.
Currently, this series has only been scanlated up until this volume, so I will take this as an opportunity to drop the series and not read any further volumes. Goodbye, catgirl lesbians. Sad to see us part like this.
