dark is a human who is in a really bad place and he needs money so someone offers dark alot of money to kill lucifer. Dark goes and attempts to kill him but he can't bring himself to do it. He backs out and is caught by guards. The guards take dark to lucifer and lucifer is about to kill him but he sees the good in dark. He sees something in dark, no one's ever seen and he spares him but on one condition. Dark has to work as a personal servant for lucifer until lucifer decides to relieve him from his punishment. At first lucifer treats dark like absolute shit. Like a worthless human but after about let's say.. 4 months.. Lucifer falls for dark.
