A ghost and vampire who are best friends or lovers and have been for centuries.
Many options apply.
Like they couldve gone through Hogwarts together at the same age and when the ghost died and came back the vampire chose to become a vampire to not be parted from them.
Or the human brefriended a ghost, fell in love, and then didnt want to have the ghost watch them grow old and became a vampire or noticing the ghosts saddness at everyone they love growing old and dying chose to change.
Or they were both killed by a vampire
Thanks go to the marvelous MJ for her sensational set.
