I think author is trying to make mc see that they are not what monsters he made him out to be but fragile looking girls inside, but if that is what is going to happen I dont think it will work on viewers side
edit: on second thought, I m not sure, it will probably play down as, mc dealing with the girls trauma, have second thoughts about quitting, girls becoming restless so they dig deeper, misunderstand what is happening and cause a commotion, mc steps up to clarify the situation, girls apologizing and trying to leave mc alone, mc stepping up and not leave them but drop in a big event to slow down the plot (dunno a war between conturies or smth) but this will probably end the manga and authors nowadays doesnt really want to go there so probably not where this is headed
