How would the yanderes feel about having an autistic darling who is full figured and has down syndrome? Would They exploit that to try and manipulate their darling or do they have at least a modicum of morality left? (Ignore this if it makes you uncomfortable, do not feel pressured to answer if you don't want to.)
I’d feel bad for deleting this but might as well bring up a general opinion on me writing these things, while not disregarding your ask completely.
So when it comes down to it I believe a Yandere will take advantage of anything whether it be mental or physical. Even if they don’t quite know your condition. Some characters will be sweeter about it, the overprotectiveness kicks in, insisting you need to rely on them, it could get a little demeaning in an obsessive love kind of way. everything depends on the way they are as a Yandere.
Big thing is I try not to write for things that are super specific like Down Syndrome. Stresses me out on trying to present things like genetic disorders. I have nothing against people who have it, I’d just rather save my sanity here and now. Hope that’s okay!
