Hypothetical Facts: Lovesick

In a high school filled with fully grown adults, Y/N is a female delinquent feared by most students.

Y/N herself isn't a terrible person, of course, but nothing could prepare her for the obsessive affection of her schoolmate, Ben Shapiro.

Ben has been obsessed with Y/N ever since she once called him a 'nerdish loser' during the first semester, and this obsession may go too far once people Y/N interacts with begin to turn up dead, threatening both the entire schools reputation and Y/N's safety.

Whatever will the delinquent do about Ben Shapiro, and can she keep people around her safe from him?
