Adam (don't leave me)

You were Adam's partner, but you decided to break up for several reasons and you left with Lucifer
Years passed and the Extermination had arrived. You were walking when you ran into Adam again; you didn't know what he wanted, but he asked you to come back. You didn't accept, and before leaving, he told you

Adam: If you want to suffer with him, that's your choice.
He left with some tears in his eyes; you felt bad too

Have fun little friend
