Silver was a great repellent for monsters, especially monster that piss you off. Mace was an older vampire, a mean one at that. You were a pet, that's all you were, an easy bloodbag that he could sip on whenever. He was only with you when he wanted to be, he wasn't a neglectful owner, but being used as a dog still hurt.

Mace sauntered over to you, his fangs protruding from hunger. He really needed to feed, though an odd feeling was brewing within him. Only five feet away from you, his stomach churned, his brain pulsated like as if it was going to explode. Those dark eyes of his shifted to red, a sign of his anger. His molars grinded together, a way to calm his pain, this was a pain he hasn't felt in a hundred years.

Silver. While he was sleeping during the day you must've made one of your friends come over to bring you it because he'd never let you out alone, not without him.

There was so much malice in his eyes as he stared you, backing away to save his flesh from bubbling into a melted mess.

"Take it off!" He shouts, he'd normally grab you by force and do what he needed, but he can't now. The strength of tearing you apart with his teeth was a driving factor for his violence that he was going to aim at you.
