True demons.

Demons are well known for being evil, well you're wrong demon have been serving us for centuries. This has started with the first demon king. He was so evil that he hated humans but then a sudden thing has happened,while the demon king was on a verge of dying from an illness a human was wondering in the area accidentally stumbling upon them.

When the human saw the demon king and he's servants the human immediately helped the demon king. The demon king was so thankful he asked the human what would he like on return. "......" the human said nothing "do you want jewelry? Money? Food? Revenge?" The demon king asked."help" the human trailed off "i want you to help and love humans that can summon you." The human continued ".......but we're demons we're supposed to be evil and all"the demon king protest. It's not like he didn't want to help its just human may laugh at him saying that "what? A demon helping a human? Yea nice try! I'm not gonna fall for it!".

"Well you'll never know until you try right?" The human said. The king then nodded. He then announced it in the underworld, many demons did not like this at all but the demon king tried to explain to them what happenedand they all agree to this new rule.

It's been years since that wish was granted, the demons have made a huge discovery that by eating humans will give them more power but they can't walk on sunlight. The demon king then made a new rule saying "eating humans is a taboo to us! Don't forget that we are serving and seeing humans too! Anyone that eats a human shall be beheaded!" The crowd was silenced but then agreed to the king.

"And that's how the demons started to serve humans." F/n said finishing the story. "Father if the first demon king hated humans why did he granted the humans wish?" Young y/n asked."Well sweety you see

He fell In love with her."
