So a yandere is someone who's obsessed with a person they love, yeah? Most yanderes are based off of romantic or sexual love, but what if there were yanderes based off other types of love? Like familial love yanderes; two parents that are so overprotective they would kill for their child, or a teenager whose entire world revolves around her little sister. Or platonic love - somebody who is always keeping a watchful eye on their friend that is trusting to the point of gullible or gives away their heart too easily. Or even aesthetic love yanderes, a person who is so obsessed with getting down the little details of another's appearance and mannerisms it crosses over into stalker territory. It would be interesting to see something like that.
