Especially when they are both children of the demon king and the high deity. They have to communicate with eachother in secret. They send letters laced with their magic to eachother back and forth. But what happens when the Arc Angels find out and strip the Angel of their magic. The Demon doesn't get a letter for a while since the Goddess is now weak and unable to send letters.
