Dracula Jaimsa
I was thinking of a Jaimsa based on the novel and films of Dracula, but without the tragic ending, rather a happy ending. Jaime and Sansa are a couple and they are the kings; there is no twincest here. The tragedy occurs when Sansa dies, causing Jaime to curse God and become a vampire, or be cursed with immortality. As the years go by, Jaime finds no meaning in his life because Sansa is not in it, and he misses his wife.
However, he would no longer be alone, because by a twist of fate, his wife was reincarnated many years later. Now he has to prove to Sansa that he is her soul mate, her life, her love.
What will happen to them both? Will Sansa manage to remember her past life as Jaime's wife, or will her present life force her to distance herself from him?
