Another sign is over - monitoring. In many stalker friend stories, you can see that the stalker friend constantly checks your social media, texts you too often, and seems to always know what you are doing. For example, if you post a photo on Instagram and within seconds they comment with details about where you are or what you were thinking when you took the photo. It's a bit scary.
Perhaps it's a neighbor who has some sort of mental illness. They might have developed an obsession with the main character for no clear reason. They see the person through the window and start to stalk them, seeing them as an object of their strange fixation. Another possibility is that it's a criminal who has randomly chosen the house to target. They might be casing the place for a robbery, but their presence in the window makes them seem more like a stalker.
The motives could be many. It might be obsession. Maybe the stalker has developed an unhealthy fixation on the recipient, perhaps because of something they saw or heard about them. It could also be revenge. If the stalker feels wronged by the person in some way, they might use the mail to intimidate. Another possibility is mental illness. Some people with certain mental disorders might engage in stalking behavior without fully understanding the inappropriateness of their actions.
Stalker fiction is a genre of fiction that typically involves a character who obsessively follows or stalks another character. It often explores themes of obsession, power imbalances, and the violation of personal boundaries.
Power and control is also a big theme. Stalkers try to assert power over their victims. They might threaten the victim or their loved ones to get what they want. In some stories, the stalker will try to isolate the victim from their friends and family so that they can have complete control over them. It's a very dark and disturbing aspect of stalker stories.
A character who could be the stalker is Gentle Criminal. He has that sort of flamboyant and devious nature that could lead him to stalk All Might out of some strange admiration or to prove himself as a worthy 'opponent'.
Stalker fan fiction refers to fan - made stories that revolve around the idea of stalking. Usually, it uses existing fictional universes and their characters. For example, in a superhero - themed fan fiction, a villain might be written as a stalker of a hero. It's important to note that while it's a form of creative expression, it can also make some readers uncomfortable due to the nature of the stalking theme.
One famous 'stalker novel' is 'Lolita' by Vladimir Nabokov. Although it's a complex and controversial work, it has elements of the narrator's obsessive and inappropriate pursuit of a young girl. Another could be 'Gone Girl' which has some aspects of stalking in the relationship between the two main characters where there are manipulations and obsessive behaviors.
I don't think they are common. Schools are communities where people know each other, and there is a certain level of transparency. But it's important to note that any form of stalking, even if rare, is unacceptable. There could be cases where a student has some mental health issues that lead to this behavior, but it's not the norm in the school setting.
