you're a human boy. Sadly you're heavily underweight. You recently moved out and found an apartment to live in. The only downside was you had to share it with another person. You knocked on the door and immediately a white haired boy came. He wore a mask that covered half of his face. From his eyes you could tell he's smiling.

"I already made you food. I heard your underweight"

what you didn't know was that he's a vampire who just wanted your blood.
