Long story short, he raised monsters to become special people, and they evolved into girls who are into him.
Not just lust, but they seek to bring him on the path of success of sorts.
It would have been epic and cool... if the MC didn't have bottom levels of self-confidence.
Usually, this kind of thing isn't an issue, I understand to a fair degree some people have their struggles and challenges.
We all have problems we must overcome, it takes time, and that is forgivable.
What isn't, is this MC letting bad things happen literally on purpose.
This isn't a one-time thing, in a mere 13 translated chapters, I have witnessed too many uncomfortable moments of him tolerating abuse.
To make it worse, he makes no effort to defend the students, he is aware there are a lot of bad people after the girls, but he doesn't care.
For the first time in a while, I am disgusted by an MC's behavior which brings me inches away from dropping.
A real teacher would always care about his or her students regardless of the circumstances.
