This was a frustrating read for me.
First I was confused by the time-jumping (high school, then middle school, then high school again?)
If a chunk of this story was set in middle school, shouldn't it have been at the start of book 5, before the time skip?

Also, I absolutely detest pushy love interests who keep asking and asking and asking, despite constant rejection. NO MEANS NO, BUDDY. BACK OFF. But I was pleased that that was resolved by

Rin saying no, forever.

If it had turned out any other way, this would be a 2-star.

Finally, all the weird rival stuff with love interest Akira. I do LIKE how they gave her more depth than just "she's a mean girl who wants to ruin your relationship." And she had legitimate motivations behind her scheming. Heck, she even made this series finally pass the bechdel test, so. Good on you. But I still don't get WHY she was so hung up on Kouki to begin with? And what was with all that stuff about her brother that never went anywhere...?

Tl;dr, this series has become waaay too much all about the high school drama. I want more "Daikichi being a good dad to Rin," damn it! He had some dad moments, like giving Kouki

money so his gf could have an abortion

and consoling Rin after

she officially dumped Kouki's ass,

and I like that. I like seeing him parent teenagers as much as he parented children.

Also, why did

Nitani turn Daikichi down? Was she lying about the other guy, or...?

?! I'm confused...

Sigh. Here's hoping volume 7 is better.
