Just for if this ever get picked up.
This entire manga is scumy NTR.
You would assume many of the "ntr" scene just our beloved teacher illusions, but later on you kinda find out, actually those scenes aren't just illusion, while our beloved pathetic sensei got a personal harem like thing, but he mostly just have illusions, rather than actions, while his beloved girl got ntr'd away and that point I assume the mangaga just goes deeper and deeper in the rabbit hole.
So if you ever pick this manga up, drop it after the first few chapter if you don't wanna get yourself in a very depressing and pathetic ntr...
I liked the main setting, it could be a nice harem, romance manga, but I read the whole 102 chapter(at this point I write this comment that's many raw I found) and even only the first 26 chapter was translated and I couldn't understand a word from that point, at the end I was able to put the pieces together just from the pictures and it's a very depressing ntr story.
I couldn't get it out of my head for days. So if you like me, for your own safety, drop it before it could do the damage, don't fall into this trap.
