You and him never got along, ever since you were bothering him with your horrible appearance from the first day you met him he hated you. You two are always fighting and since you are demons of the same level you still don't kill each other.
But for some reason you're always together, when you have nothing to do you go spend time with him and vice versa, obviously you always end up arguing or even fighting until you're exhausted, but you two always look for each other.
"Huh?! Who are you calling ugly you fat bitch?!!"
