for sub yanderes (a friend of mine is writing a series about it with the brothers which is really good):
-masochism works well. also very funny if you wanna punch them in the face but they'd get off on that
-protectiveness/overprotectiveness is good, especially if they're sneaking around your back to torture/maim/kill people for any perceived slight or threat to your relationship
-shows of power (possibly involving bloodshed) as a romantic gesture. sub yandere presents you with the head of your enemies for a headpat
-possessiveness is a hallmark, but a subby yandere could focus more on "no one else deserves to touch you" part of it, and "no one could ever make you feel as good as i do" etc.
-worship kink. sub yanderes who want to worship you as their god/master/whatever
(I know exactly who you’re talking about too, I follow them their name is demon-fucking-therapist, right?)
That’s a very helpful ref! My main concern is the sub coming off as too dommy, so I’m trying t o figure out good ways to word stuff too.
Possessiveness is by far my favorite aspect of it, and the protectiveness so 100% gonna use those!
