I don't think that this story in particular can be put on "rape for the sake of rape bl" category. I usually agree that most bl have a huge problem with consent but this is not a love story. They are fucked up ppl, the uke has basically no morals and is capable of anything for power and the seme is a suicidal mess, everything about them is a power play, even if they "fall in love" will be toxic or out of codependency.
I'm extremely intrigued by this plot, it's really dense but captivating
