Hidden Agony (Vampire Knight: Zero x Reader)

"A vampire can be many things, but to humans they're monsters. Monsters that kill and drink blood from their prey. I once heard a quote from a show and one line fits what I'm trying to explain:
"They pose as humans, even though they have no understanding of the human heart..."
I don't mean to kill, I don't want to hurt anyone but...it's in my nature. I have to if I want to continue "living". I'm telling you, I do care. I care about humans I mean after all I had been one, my family knows nothing about what I am and to keep them from knowing so I "disappeared". I feared that I would hurt them.
I know what it's like to have to be strong and hide your pain. I couldn't show any sign of being vulnerable...
It's here where I can be my old "human" self, it may be bad to hold onto the past but in our situation, it doesn't matter.
Zero...Let me help you..."
