YES. IT IS ABUSE. Safe bdsm is formed upon trust of both sides and if anything is done during the play without the consent and knowledge of either parties, it is gaining power over the other and the goal is not to induce pleasure for both, making the bdsm play unethical. I’m sorry that you’ve romanticize over stepping boundaries and borderline abuse.

Yeah maybe your right and we have different level & understanding of BDSM.. And I refer the HARDCORE one..
But that doesn't mean that I'm ENTIRELY wrong..
For me, most of the manga I've read with a genre / tag name of BDSM, not all of them have what you called Safe BDSM (like having a safe word or always mutual consent, etc.)
Its just that, at the last chapter, I think MD haven't overly stepping the boundaries, that to be over-criticize like that, and classified it as Abuse..
Just also stating my opinion, if you don't mind..
Why is MD GETTING HATE YALL???? HE DIDNT DO SHIT????
