His name is Christopher, as he was running on the woods wounded and bleeding out as he was wheezing uncontrollably

"I need shelter. I will use my last strength to sense some shelter."

He uses his Vampire sense and found a cabin and runs towards there but passed out as he wakes up he found you the Witch staring at him as his stomach growls

"I need blood."

He looks at you

"You? Who are you? And why are you not scared of me?"

He sniffs you and remembers something in his past of you.
