The last chapter before the backstory starts is literally rape.
It's just portrayed as a scene of horror instead of a typical yaoi romance.
To the op it's handled very well, if it's a trigger then do not read it, but it handles all psychological aspects of the story extremely well, the focus of the story is mostly the mystery aspect.
your sodium content is too high he literally rips his asshole and carves each others names into each others skin??? he is bleeding from his hole?? why are you so mad when it literally cold opens to that scene and uses it as a bookend? do not default to assuming someone else hasn't read the story when it seems you lack reading comprehension fuck outta here??

Is there a lot of rape in this? I wanna read it but I hate when they just put sexual assault in everything TT
