Now I want a series where a demon pretends to be a human doing good deeds like this guy and eventually angels start trying to reward him only for him to spoil them into a slothful state of spoiled bliss, eventually even goddesses start trying as somehow all the angels failed to reward him and he even got more good boy points after their visit.
His overall evil plan? the downfall of the heavens by bringing the angels and gods down to a fallen state. He thinks he's winning when they can no longer move (due to blissful happiness) but all he's doing is improving the moral and workflow of heaven and hell when he needs to assert his dominance over other demons.
