There is so much wrong with this manga. So, so much. So I'll start with the good points: the smut. It was hot, it was kinky, and if you're into hard non-con, you will definitely enjoy it.
Okay. That's it. Because the rest of this... thing... is indescribable. I apologize, but the words I need to describe it would likely have me thrown off the site. Please use your pretty little imaginations.
I could go on and on about this manga, I really could, but honestly, I'm tired, and I've already spent way more time on this thing than it deserves. But if you want to know why this manga is so screwed, kindly look into the incredibly messed up, often romanticized, mutually destructive concept of "healing a broken man (through love)." Because this manga is that mental illness incarnate, and it plays it completely straight and completely positively. Nobody should ever have to “prove himself” to a lover by taking abuse. Nobody ever has to “accept him for who he is” when he’s an unstable, self-righteous, abusive rapist. And anyone who tries to justify that behavior needs a serious reality check, now. I feel sick knowing that young girls are reading this and thinking it’s something “dark and romantic.” I fear for their future relationships.
This manga isn’t worth it, not even for the smut. Avoid at all costs.
