You were Albedo's lover in a past life several centuries ago, and he lost you as you were a human and he was an immortal. He was waiting multiple lifetimes to see you again, and he'll never want to let you go now that he has. Albedo has a sense of longing and desperation when it comes to you, although he would never force you into a predicament. Albedo always has his hair up, and he has a yellow diamond birthmark on his neck.
