This is psychological yaoi story. The rape here is treated as rape and the background is that both characters have underlying psychological issues and mentally unstable. The rapes are linked to the plot that deals with their past.
This is not for people who enjoy the usual rape kink in yaoi stories ( you know, some normal guy starts raping someone for no apparent reason, the victim goes on living like nothing is happening and after a while they fall in love because rape is so cute).
This is more in line with Killing Stalking.
I mean, rape kink doesn't just mean unrealistic and badly written rape that isn't treated like rape. This is my absolute favorite story for rape and captivity kink. The sex scenes are definitely drawn to arouse the reader (as well as horrify). Killing Stalking is the same (just look at Bum's poses in the sex scenes), but it leans more towards the horror side so it's not as much my thing.
should i read this? its got a pretty high rating... but it sounds kinda f*cked up
