Albus Dumbledore/Gellert Grindelwald. The summer of 1899 ends with less destruction and heartbreak, but love is not a victory march and the darkness is still a seductive temptress. "It is not in the stars to hold our destiny but in ourselves. I refuse to accept that there is any future where the world is better place with us apart."

In which Albus leaves with Gellert, and the world bleeds.

He wouldn't be Gellert if he coloured within the lines. And Albus kind of loves him for it; his life was so mundane, so confining, before Gellert Grindelwald.
