Tbh idk what to feel about this? I want to hate the Sensei, but it's not like he did something so wrong. He just broke the heart of the two students after he got raped by multiple men, and a person who he thought he loved in the past. This does him no justice to do wrong, but I understand where he is coming from.
People take rape so light in this comment section that it disgust me, I mean that cruelty of the Sensei is his defense mechanism to cope with his trauma. Not justifying, just explain.
Try getting raped by the person who you thought you loved and his sick friends, then let's talk :/
