Thanks for the mass release. I'm guessing this was the final chapter?
I loved the series a lot surprisingly. The characters felt so human, Heisuke never did change, but he did grow a little bit. Aki was a nice realistic child character. The senpais graduating made me feel pretty nostalgic.
One of the few high school SoL which focus on boys over girls. The relationship between the characters was great too.
We never did get a definitive answer over Heisuke's father, probably a mystery which wasn't meant to be solved.
Thanks for translating this, and thanks to the author for making such a good story.
