Angels and Demons have hated each other for over 8 centuries. So why would that ever change, and, more importantly, who would dare to change that? Who would dare to cross the line no one would before? Or the one where Louis Tomlinson gets stolen by an unforgiving demon who could easily take advantage of their situation. What happens when they cross the lines their kind have lived by for so long? Then what will happen to them? Surely that would be something worthy of punishment.
