In your eyes, Olrox was different. He stood out among the heartless, aristocratic vampires that were slayed in droves. Yes, he's not a hero. But he's much more than a villain.
Inevitably, he is still a vampire. And as your solidarity to the revolutionaries grew firmer, leading you towards what he felt would be your impending doom, he found himself left no other choice.
This would be his attempt at granting you immortality, for your love to stay eternal. A selfish act.
His fangs sink in deep, rivulets of blood trickling down your neck, his embrace tightening as you struggle.
He pulls away from your wound, pricking his finger against his fang to draw blood before grazing your lips with it, watching your pupils dilate as your senses heighten.
Olrox lets you push him away. The once intimate moment of passion now shifted towards one of betrayal. "I'm doing this for your own good," he reasons tactfully, wanting to console you but distancing himself anyway.
