You didn't know why but you remained still in his bed, curled. Jeff had just came back from training, you and him had different training times so the only time you two saw each other was mainly during downtime.
Jeff laid down next to you lighting a joint, you snuggled against him, cold. "Wish we had training together, boring without you there." Jeff murmured.

Alias Jeff the Killer Jeff Jeffrey the Killer Joker-Reject / Rip-off Relatives Margaret (Mother, Deceased) Peter (Father, Deceased) Liu (Brother, Presumed Deceased) Occupation Serial Killer Powers/Skills Hand-To-Hand Combat Prowess Enhanced Senses Athleticism Inhuman Durability Inhuman Stamina Great Stealth Status Alive Species Human Gender Male Hobby Murdering people to satisfy his bloodlust Stalking his next victim Goals End as many lives as possible (On-going) Kill his parents and brother (Succeeded) Kill Randy, Troy, and Keith (Succeeded) He is an adolescent serial killer and registered Creepypasta. He was disfigured after being set on fire while fighting a gang of bullies and lost his sanity after witnessing his "new" and "beautiful" face. Origin Jeff was a 13-year-old who moved to a new neighborhood with his brother, Liu, and their parents. On their first day of school, they were accosted by 3 bullies named Randy, Keith, & Troy, whom Jeff brutally beat up after they threatened them with knives. Liu took the blame for it and was arrested, sending Jeff into a deep depression. The bullies later attacked Jeff again at a party, and Jeff killed one of them, but not before getting covered in bleach and lit on fire by Keith. During this fight, Jeff's mind permanently snapped. When Jeff woke up, he was at the hospital and his head was wrapped in bandages. When the bandages were taken off, it was revealed that his face had become disfigured and ghastly pale from the burns, with bright red lips and a leathery texture. Jeff said that he liked his face this way and laughed hysterically, but the doctor foolishly thought that this insanity was merely a side effect of the painkillers and let Jeff go home. Later that night, Jeff's mother found him carving his face into a permanent smile so that he would no longer have to exert energy to smile, as he put it, and burning off his eyelids so he could always see his face. Jeff's mother went to her husband to tell him that their son had gone completely mad and needed to be killed, but Jeff caught them and stabbed them to death. This woke up Liu (who was recently released), with Jeff telling him as he was about to plunge the knife into his body, "Go to sleep". Jeff then went on a serial killing rampage, killing those who refused to sleep at night, and as the story continued, Jeff renamed himself "Jeff the Killer". Slender Man There are many different ways in which fan content portrays Jeff the Killer and Slender Man in relation to each other. Most fan works depict Slender Man and Jeff as mortal enemies, each showing off their skills against the other. Depictions of Jeff typically show him going into combat with Slender Man using his knives, while Slender Man is usually shown using his tentacles. Fcac53475097d05a172b92613c9c571f6b1c460e hq Jeff the Killer Vs. Slender Man There are even some various fan works that depict Jeff the Killer as one of Slenderman's proxies, often painting Jeff's image as some kind of super-proxy that was discovered by Slender Man shortly after murdering his family and escaping to the forest. However, many fans do not exactly approve of this particular fan-work, because they tend to argue and state that Jeff would be 'too insane' to be controlled by Slender Man. Appearance Jeff has extremely pale skin and burnt off eyelids, giving him an even more ghostly appearance. Jeff later got his most distinctive trait, the Glasgow smile that he had carved into his face. His build is commonly described as thin, but with some lean muscle tone at the same time, and reaching a height of around 5'10" to 6'0". In various fan depictions, he's typically portrayed in his late teens or early twenties. His clothing normally consists of a pair of black dress pants with a white hoodie, like described in the story, which is sometimes stained with fresh and old blood from his victims. Personality Before being burnt alive, he was a quiet and fairly antisocial teenager, not that people actually knew him very well. But shortly after the incident, he became torturous, aggressive, bloodthirsty, and violent, making him one of the most dangerous serial killers in his hometown. Jeff is widely known for luring his victims to an eternal slumber, using a kitchen knife and eerie but soft tone of voice. Even though he prefers to murder his victims with knives, he is more than willing to use any weapon when placed in a desperate situation. He is an extremely stealthy and mischievous individual, able to break into victims' houses almost always without getting himself caught in the act. Powers and Abilities Despite being an average human, Jeff appears to wield incredible supernatural abilities that only apply to his human attributes, such as incredible stealth, speed, and supernatural strength used to mercilessly slaughter his victims. Jeff is shown to be incredibly durable, being able to overcome his parents and brother simply by gutting them. One thing that makes him stronger is his intense hatred and bloodlust to keep him going, as well as having great stamina. In recent years, Jeff has been depicted as being a charming individual, manipulating people into trusting him, only to betray them later.
