Just finished chapter 2, so don't know how it will change, but for now, this is not BDSM. There is only one "consenting" party here, the MC. He "consents" to getting raped, he consents to the sex. His "partner" is not consenting - he doesn't know that MC chose him and is full in, he is raping MC. He is a rapist.
This is both less and more messed up than the usual yaoi. Less because, technically, they're both consenting. More because it's, in a sense, trivializing and glorifying rape to a much higher degree than usual.
In before "yeah, yeah, this is a fantasy, it's not that deep, read if you want don't if you don't"... it is that deep. And one can enjoy reading something while still critically discussing it.
The dynamic in the beginning had potential, but the last few chapters were just ick. Ick lack of consent, ick power dynamic, ick use of side characters as props (by beating them up to show jealousy/dominance). And ick, ick, ick having sex while one hand is bleeding profusely. Also, this is beyond deus ex - ML doesn't seem to have a life, he always shows up around the MC when required to further the "plot". Like what?











This is like yaoi inuyasha conflict >.<
