I really do think that Shinobu will largely have a good ending minus some hits because the author is still coping with, perhaps, an ex-boyfriend she cheated on and he just ghosted her after…
I believe this good ending will come because of the ongoing backlash from 129. If she outrageously dunks on Shinobu again it will look to all the normie fans that she is adding insult to injury and everyone except netobros will simply stop buying her manga.
From what I know japanese customers are leas forgiving of being insulted by those they spend their money on.
