Notes:

Got to add more sources if you're interested in reading the story outside of just the twitter chain:

I'm surprised that out of all the weird and/or redundant pages that get made here, there's no general Yandere entry. Had to really put it here considering the image type, but please move this if I didn't find the proper place myself. Or delete if the content is not suitable/it's a repost, whatever.
