Was that resolved though? It didn't feel like a complete conclusion to me.
I mean to me it was more saying that he literally cant save everybody, since in his flashback, the old teacher he wanted to talk to (I assume) told him that the easiest thing to do to a woman who begged for his love (in this case the student is begging for something similar to his love), the easiest thing to do is to embrace them, but that isnt "saving them". the older teacher said he couldnt save everyone with all those constraints, choosing who to touch and not to, etc.the teacher embraced him which isnt "saving" him buy giving him temporary content. it doesnt hell him with his problem because he is going to continue having a problem the following days after. or at least that's what I believe it was talking about. maybe we will have a follow up with answers but I genuinely enjoyed that chapter. it showed that the teacher isnt a "saint" who can save everyone
She's not wrong.
