Geez girl even Im freaked out
She has been talking so much about the ruin shes sure to face, Im so curious of it... Muhehehehehehe.
-actually, I think the ruin is already happening. We see it in how at the start and middle of the chapter shes constantly denying that shes doing this because shes attracted to her (another girl, and her student). She knows that she cant keep up that denial for long, and we see that break when shes touching herself at the end
The ruin is just the end of things she thought were normal and how things were meant to be to something less conventional but that she pursues purely out of desire, like earlier in the manga when she was first getting interested in the main character girl I already forgot the name of. Specifically when she talks about how everything is collapsing "brick by brick" as she walks forward with it
Yeah 👍
