I'm just not into CNC play. I just don't like anything that deals with rape and what it's associated with period. I know they have a safe word and that Yuan literally asked for it, but I will never willingly read it even when the safe word hasn't been said. These two are in a VERY healthy and trusting relationship, and I love that for them but these last few chapters just aren't for me. Give me rough sex all day long! But this? Yeah, no.
Also, I refuse to read any characters labeled as "black flag". Yes, I have not read anything that the characters Zhenya or Ilya are in as they will more than likely cause me to violently vomit either mentally or physically. Not shaming anyone for liking it, but not for me.
