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.
One story could be about a girl in a school setting. She was secretly in love with a boy. Whenever another girl got too close to him, she would start to spread rumors about that girl, trying to drive her away from the boy. It was a really creepy situation as she would always be watching the boy's every move and the girls around him.
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.
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.
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.
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 first real - life yandere story I know is of a man who was overly attached to his sister in an inappropriate way. He didn't like it when she had male friends and would try to isolate her from them. He had this extreme jealousy that was not normal for a brother - sister relationship. Another story is about a girl who was so possessive of her best friend that she would get angry if the friend spent time with other people. She would often guilt - trip her friend into spending more time with her. The last story is about a person who was obsessed with a famous actor. They created a shrine in their room dedicated to this actor. They also tried to find out where the actor lived and would sometimes lurk around the neighborhood hoping to catch a glimpse of them.
Most real - life 'yandere girlfriend' stories are not as extreme. Often, what seems like yandere behavior can be a result of insecurities. A girl may have had bad experiences in past relationships or might have self - esteem issues. So, she acts overly protective or jealous. However, it's not the same as the full - blown, often dangerous yandere concept from fictional works.
There was a yandere - like situation where a young man was obsessed with a co - worker. He would constantly leave little gifts for her at her desk. But when he saw her talking to another male colleague at a party, he started making mean comments about the other guy to her, trying to make her dislike him.
In a workplace, there was a man who showed yandere tendencies towards a female colleague. He would always try to be near her, and if she interacted with other male colleagues in a friendly way, he would give her the silent treatment and try to sabotage their work relationships. It created a very uncomfortable environment for everyone.
