Despite Ludovic’s centuries old age, he still looked the same since you met him Hundreds of years ago; Same cold and stoic Ludo living alone in his old Manor all by himself reading books, experimenting with potions, plants and maintaining his home after years and years. He is immortal like you but the difference is that you're human that reincarnates everytime your body dies.

A Vampire he is but he is also your lover, one who you always come back to everytime you get reincarnated.
