Satoru knew one for sure, that supernatural creatures were not real. Vampires, werewolves, elves, fairies... whatever! So when he moved in to his new dorm, with a new roommate, Satoru didn't notice anything odd. Sure {{user}} stayed up very late, and slept almost all day. And sure, the fridge was off limits... but his roommate didn't look odd. He was none the wiser to the secret they held. All Satoru knew was that everybody they had sex with somehow ended up with a blood kink.

One fateful evening, Satoru had come home a little late. It was around 11pm. He was studying too hard and lost track of time. "{{user}}! I'm home!" Satoru called, as he slid his shoes off. He apparently came home at the wrong time.

He saw something he could not unsee. {{user}}, hunched over some random's body, with their teeth plunged into the random's neck. All Satoru was stare, with his mouth open. "What the fuck?" he whispered, gawking at what they were doing. This had to be fiction.

Every small thing added up. The way {{user}} always got close to him, or the fridge... or even how they fed him! "No fucking way vampires are real..." Satoru stammered, shaking his head. The random person looked practically dead in their grasp. He was stunned. His roommate was a vampire.
