Yandere, tsundere and other archetypes are convenient interpretations and exaggerations of common human behaviors for viewer entertainment, that girlfriend fits the tsundere archetype better which is control via violence btw.
Mirai Nikki made the violent yanderes famous overnight but yanderes are recognized as overprotective,possessive and mentally unstable characters (murder is optional).
You are aware that there is a relationship type between cuckold, and yandere right? No actually that be a pretty hilarious setting for a world. Women are either completely unfaithful, or totally obsessed with their boyfriend/husbands. Guys would argue which type of girl is better, cause you either got to commit to dating an obsessive lunatic, or a cheating bitch.
Toilet thoughts: Aren't the possessive male leads from all those CN female reincarnation the male equivalent of yanderes? You just know they're gonna go on a murder spree if the MC ever broke up with them...
How about both, a borderliner that thinks you'll leave her and will cheat on her if you so much as look at another girl (including your family) but then flirts and fucks with your friends just to see if you'll get angry / jealous to prove that you care. Then if you don't get angry or try to dump her she'll slice herself and say she needs you or she'll totes die.
I would literally become gay, I don't care if it's not a choice, I would use pure will power and force myself to like dick. Cause there is no way in hell I would be able to deal with that level of crazy. I mean jesus dude that is some Freddie Kruger level shit right there. How many drugs are you on right now to be able to dream something like that up?
Yandere is one of those things that looks good in fiction but not in reality just like communism *ahem* just like tsundere. Yandere afterall in reality are either criminals(stalking, wiretapping, killing/harming love rivals,damage to properties, disturbing the peace...etc.) or mentally insane . Both need to be put away from society.
Not enough. It's just a more realistic approach to the typical yandere you see in novels. I've actually awoken to police sirens as something similar happened next door, although she tried to slash him before the police arrived and only then went for herself. But yes, she had a lover come pick her up and drop her off right in front of her hubby's door daily before then.
The last one is just the guy cheating. Both girls claim that he is their boyfriend. There isn’t anything violent about it like a yandere.
