A common theme in yandere horror stories is the blurring of love and hatred. The yandere starts with what they think is love, but when things don't go their way, it quickly turns into hatred. For example, if the person they love shows interest in someone else, the yandere's 'love' morphs into a desire to harm or destroy. Also, themes of psychological manipulation are often present, as the yandere tries to control the life of the person they're obsessed with.
It depends. If the portrayal of the yandere girlfriend is done in an interesting and nuanced way, it could be appealing. But if it's overly stereotypical or one-dimensional, then no.
There's a yandere horror story where a young woman moves into a new apartment. Her neighbor, a seemingly nice guy, turns out to be a yandere. He begins to manipulate her life, cutting off her contact with friends and family. When she tries to resist, he shows his true, violent nature. These stories often play on the fear of being the target of someone's unbalanced love and possessiveness.
A gift from her in a yandere manga can have multiple meanings. It could be a sign of the yandere's obsessive love, an attempt to control the situation, or a way to create drama and tension in the story. Sometimes, it might even be a red herring to mislead the reader.
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.
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.
Well, such a girl is often obsessive and possessive. She might go to extreme lengths to keep the person she likes close to her, sometimes even using violence or threats.
