Oh, thanks for translating this deleted chapter!
Yeah it's not good for this "arc" for the teacher to also become a horny freak since Erika becoming one does NOT help with the class observation. Also Iike the others said, it's Sou complimenting someone into becoming delulu again.
And there we go, there was no backlash nor drama involved.
As a webcomic artist myself that has a ton of delays, I really really feel his pain about inconsistent updates. It definitely feels shameful to post after a long delay, and it gets harder (and imposter syndrome becomes stronger) the longer it goes on.
I also know the pain of writing, but needing the posts to be consistent, or at least attempt to, one can post their chapter/page without being completely happy with it just to keep the update schedule up.
All of these also saps the fun out of drawing/writing the series...
