AU MEME │ Klaroline was predicted by Bonnie, as in a prophecy. 

“There’s a man. The only one of his kind. He could have let you die once, but he didn’t. You should hate him with a passion, but you don’t. You’re his fatal weakness and he’s your greatest guilt. But despite everything else, you are each other’s redemption.” (Bonnie’s prophecy towards Caroline and Klaus)
