ML isn’t a r@pist though. He himself goes into a trance and does things he himself despises, which makes the s*xual encounters SA for him too. It's a sh!tty situation for both of them but ML is absolutely a green flag.
Please, that's a plot devise so the author can write/draw chapter after chapter of the MC being raped, crying, and saying it hurts. That's not entertaining to me. The author uses the story to excuse the many rape scenes so people like you can say 'it's not his fault, he's a victim too'. but it's glorified the way it's done. I don't judge if this is someone's cup of tea, it's not mine. But I do think you should employ some critical thinking and don't be fooled by the poor ML has to rape him again and again because he can't help it.
Continued rape, chapter after chapter, abusive, and uke feeling like they'll die but saying " I like you" and taking care of his rapist... just a big ick.. don't need this brain rot.
