What's a hero to a villain (other than it's perfect half)

(Inspired by "Vices & Virtues" by Reinaeiry.)Creating a blood bond with an ancient vampire was not part of Yang's plan, but she is an Enforcer. Dealing with vampires is her entire life's purpose. She never thought she'd have to make peace with one, but the more they meet up, the more she is starting to learn that maybe... There is still a bit of human in them after all.For Blake, she never met a more reckless Enforcer than her blood bond. Caught between wanting to rip the girl apart and wanting to protect her from anything and everything, the ancient surely has her work cut out for her as the two navigate this strange relationship they've found themselves in.(“You’re getting on my nerves, leech,” Yang spat. “Keep on pushing my buttons, I dare you. You won’t like where it goes.”“No, Enforcer, it should be the other way around,” Blake stood tall, and though she was a few inches shorter than Yang, the way she commanded obedience with a simple raise of her head made the Enforcer waver. “You’d be wise not to push my buttons. I am the only ancient that resides at Beacon. I call the shots here, irritate me more and I’ll level the city before you can begin to regret it.”)
