Well, in one of the stories, the yandere figure was a neighbor. This neighbor developed an unhealthy fixation on another neighbor. They would constantly peek through the windows to watch their every activity at home. They also left strange gifts at the doorstep, which were often items that the watched neighbor had mentioned casually in conversations. It was really creepy how the yandere neighbor knew so much about the other person's life just from observing and eavesdropping.
A real - life yandere story I heard was about a person who was in a long - distance relationship. The person was so possessive that they demanded their partner to send them pictures every hour to prove where they were. If the partner didn't comply, they would start yelling and threatening to break up. Another story is about a girl who was friends with a boy. She slowly developed a yandere - like attitude. She would be really mean to any girl who showed interest in the boy. She would make up lies about those girls to the boy. The last story is about a guy who was into a girl in his study group. He would try to monopolize her time during the study sessions. He would get angry if she talked to other guys in the group. He even tried to convince the other guys to leave the study group so that he could have the girl all to himself. This kind of behavior is really not healthy in real - life relationships.
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.
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.
In another real - life yandere - like case, there was a student who was obsessed with a classmate. The obsessed student would steal personal items of the classmate, like their notebooks and pens, just to have something that belonged to them. They also sent anonymous and disturbing letters, filled with declarations of 'love' that were more like threats, which made the classmate extremely scared and on edge all the time.
In another instance, a man was yandere for his neighbor. He would secretly take pictures of her through her window. He then started leaving dead animals on her doorstep as a 'gift'. The woman was terrified and moved away after calling the police.
There was a case where a young man had a yandere - like situation. He worked with a woman and developed an intense infatuation. He started sending her hundreds of texts a day, even after she asked him to stop. He would also wait outside her apartment for hours just to catch a glimpse of her. His actions made her feel very uncomfortable and she had to change jobs to get away from him.
One example could be a person who becomes overly possessive and jealous in a relationship. They might start monitoring their partner's every move, like constantly checking their phone or following them around. This kind of behavior can be quite disturbing and is similar to the yandere concept.
One example could be a person in a workplace who becomes overly possessive of a colleague. They start to monitor the colleague's every move, get jealous if they talk to others, and even try to sabotage relationships the colleague has with other coworkers. It's a real - life manifestation of yandere - like behavior where the possessiveness and jealousy are extreme.
In a particular real - life story, a collector of dolls bought a very rare and old doll. As soon as he brought it home, he started having nightmares. In his dreams, the doll was chasing him and trying to harm him. He noticed that the doll's expression seemed to change over time, becoming more menacing. He tried to sell the doll, but no one wanted it because they could also sense something off about it. Eventually, he had to contact an expert in haunted items to deal with the doll.
In a school setting, there could be a case where a student has an extreme infatuation with another student. They start to exhibit yandere - like behavior by following the other student around secretly, and getting very angry or emotional if they see the object of their affection talking to someone they consider a rival. They may even spread rumors about those rivals to keep their 'love interest' away from them.
