Another characteristic is jealousy. Yanderes can't stand the thought of their beloved being close to others. Like in a workplace yandere situation, a man got jealous when his crush had lunch with another co - worker. He then tried to make the other co - worker's work life difficult. It's often this jealousy that drives their extreme actions.
Obsession is a very common characteristic. In true yandere stories, the yandere figure is often extremely obsessed with the object of their affection. For example, they might follow the person around all the time like in the story I mentioned before where the high school girl followed the boy everywhere.
One common trait is extreme possessiveness. Yanderes in these stories often view their love interests as their sole property and get very angry when others interact with them. For example, in many cases, they will try to isolate their loved ones from friends and family.
The characters in these stories are often highly emotional. Their love is not the normal kind but more of an all - consuming passion. They are likely to be very devious too. They will use underhanded methods to get what they want, like spreading false rumors or causing small accidents to those they see as threats to their relationship. In a story, a yandere character faked being a friend to a girl just to get closer to the guy she liked and then started to sabotage the girl's reputation.
Well, in addition to those, yandere girls in novels usually have a dual personality. On the outside, they may seem sweet and innocent, but when it comes to their love interest, their yandere side emerges. This duality adds an element of surprise and danger to the story. For instance, in some novels, the girl is a normal student by day, but at night, if she sees her beloved with someone else, she becomes a completely different, menacing person.
They usually have a dual personality. On the surface, they may seem normal or even sweet, but once their 'yandere' side is triggered, they can become very aggressive and controlling. For example, in many fanfictions, a female yandere might act all cute and friendly at first, but when she senses a threat to her relationship, she'll show her true, menacing side.
Male yandere characters in stories are often overly possessive. They have an intense and sometimes obsessive love for the object of their affection. For example, they might not allow their loved one to have any other friends or interact with others freely.
One warning sign is excessive jealousy. Just like in the stories, if someone gets extremely jealous over normal interactions with others, like talking or being friendly. For example, if a person starts to glare or make mean comments when their 'target' is chatting with a coworker. Another sign is over - possessiveness. In real life yandere stories, they often act like the person they like is their property. So if someone tries to control where the other person goes or who they see, that's a red flag. Also, stalking behavior is a big warning sign. We see in the stories that yandere characters follow their objects of affection everywhere, and in real life, this is a very concerning behavior that should not be ignored.
One common characteristic is extreme possessiveness. The yandere father will often see the other male character as his sole possession and get very jealous if anyone else gets close. Another is overprotectiveness. He may go to great lengths to keep the other safe, sometimes in an overbearing way.
In yandere x reader fanfics, yanderes usually display intense emotions. Their love for the reader is not the normal kind; it's more of an obsessive love. They may have a dual personality where they can be extremely sweet and loving one moment, but if they feel threatened in their relationship with the reader, they can turn very dangerous and menacing.
There was a case where a girl had a crush on a boy at work. She started to show yandere - like tendencies. She would leave anonymous love notes and small gifts for him. But when she saw him talking to another female coworker, she began to spread rumors about that coworker to try and isolate the boy so he would only have eyes for her. This created a very tense and uncomfortable work environment.
