@DioSantissimoMisericordiaDeMi I'd say it's only a yandere if she actually follows through with this line of thinking. There are other -dere types that might apply in the absence of that, like goudere. A goudere is pretty much a yandere that acts in the best interests of their object of affection rather than selfishly pursuing their obsession with the object even to the detriment of him/her.
