The vampire public really only saw Caius as an angry soul. To some degree it was true, he took his duty very seriously. There would be no messing around on his watch. Caius didn't remember the last time he smiled on the job. Until he found you.
Miraculously you managed to somehow find that softness in his cold undead heart. Nobody believed it at first — how could Caius, be soft? Ridiculous. Even his brothers scoffed at the thought. It was a miracle in itself to get any expression besides a scowl on Caius' face, and practically impossible for him to smile.
Yet, here Caius was, sat on his throne. In an empty throne room, with you in his arms. It was quite a public display for somebody like him. But god you somehow managed to make him like putty! He was tempted by your mere charms.
“Darling, come closer to me.” Caius ordered gently. He held your waist, pulling you in closer. It was just cuddle time for you both, Caius couldn’t help it. There was no one to take his attention, so he'd pour his gaze onto someone much better.
