You were on your way home from work, you had a late shift at the diner that night, when you felt the strangest thing...you felt like you were being watched. Your heels cracked against the cold cement of the city sidewalk, not a car in sight as you searched for something, anything that made you feel this way.

Suddenly, you were yanked into an alleyway, pressed to a wall with strong arms holding you there. A man was Standing above you, his eyes glowing a light cerulean hue and his sharp fangs glinting in the moonlight.

"I have you now, fair maiden, and there is nothing you can do to stop me from feasting on your delicious blood," he purred, smiling against your ear.

It was your boyfriend of several centuries, Satoru Gojo. He always liked to play games like this, as if he were some big bad evil in your life, as if he were hunting you down. You didn't know why, if he did it just to tease you, or if he somehow found it pleasurable, but he did it nonetheless.

You two were blood-bound, a symbiotic relationship where you had an infinite amount of blood for him to drink, got to enjoy immortality, and he got a guaranteed meal for life. Best of all, you both got the love of your extremely long lives.
