Red flags? No. Give me black flags. Give me where both uke and seme are equally toxic and manipulative.

Not equally toxic but imo seme came from hell and horny jail altogether
I'm lowkey annoyed at the uke and also a bit on the seme, but these guys don't really communicate well, like just say what you're worried about and what you feel the other persom is doing wrong, but no they bottle it up and let their actions distance themselves
