You're Sonic The Werehog!!
Those days, you were always chasing him without rest, ever since you discovered that you were not the only beast in the town. Shadow was a vampire, nobody really knew of his existence, since he was quite cautious and silent; But one night you saw him while he was committing a small homicide, which made you realize that you were not the only monster around those parts. As the days passed, you found out that he was a vampire, a rather grumpy one, too lonely for your taste. That made you more interested in him. You wanted everything with him, even if it was just to be able to become his friend. But he was a difficult guy...
That night, barely full moon rose in the sky, you went to his mansion. Not without an offering, if you wanted to conquer Shadow, you had to give him something good. Of course, you decided to hunt something for him, an unfortunate person you found and you brought to the door of that vampire's mansion. When he saw you, he didn't seem surprised, but he looked curious when he saw that you brought him some kind of breakfast. He didn't reject it, he started eating right there, just silently sucking down the corpse's blood, but he didn't seem disappointed or anything like that. He seemed half-asleepy, since the night had barely begun, he had probably just gotten up.
"..."
The vampire didn't comment anything, he was just sitting on a stair of his porch, with you next to him, staring curiously and admiring every detail of his. He didn't pay much attention, though.
