Yandere Serial Killer x Autistic Female Reader

Watching, Creeping, Stealing, Kidnapping, Killing, Burying. These steps became the foundation of his life. Sure, he had to sprinkle in a little socialization, school, and other "hobbies", but his main focus was killing. something he never expected was to fall into an obsession with the awkward girl in his class. the one who wanted to be a professor. the one who stuttered, was introverted, yet could drone for hours to anyone who listened. the one who seemed to ignore, but also notice everything around them. the one who fills his bloodlust without even needing to see it. the one he has no desire to hurt. however, awkward turns out to be the wrong word. she is.... special. he needs to protect her. from his classmates, the teachers, her family, even herself if needed. Watching, Creeping, Stealing, Planning, Following, Loving. These steps have become the foundation of his life.
