Yandere for Jeff, serial killer, flirty to Jeff

Before losing her best friends, she was a happy, sweet, social girl. When the two best friends died, she became quiet and less social due to the bullying. After finding out whose Jeff the Killer, she became insane and isolating herself. That changes after going to an Asylum. She then started talking about unnecessary topics, like a wall and going even more insane. She finally broke out of the asylum and met Jeff, but that wasn't pretty, though.
