Werewolves. Faeries. Phoenixes.

Mermaids.

Kyungsoo knows the rules. Everyone knows the rules, every werewolf pup knows that damn story. And they all know better than to touch the sea water that laps at the edges of their territory.  Because when hatred runs so deep in between races, it never ends well. And it never ends well between enemies that have felt betrayal and hurt. When history sears and burns with shameful knowledge. He knows better than to fall in love with her.

Except, guess what.

He did. 

And now fast forward to five six, seven years or so later, the whole of Exo finds themselves suffering under two adorable kids from the best of both worlds. The land and the sea. They're a little different, but they're perfect the way they are, mixed. A hint of both the warm earth and the murky secret blue lagoons. But you can't keep a secret for long I mean pfft, they know they're different.

Which is just great really, absoloutely wonderful that Luhan has to be the one telling the story. Honestly, shouldn't it be the parents who tell the stories? Why him? Hello, he wasn't the one who fell in love with a mermaid and broke the sacred rule! Luhan wants to cry. He isn't a baby sitter. He is a strong dominating werewolf in the pack.

But when Kyungsoo's son smiles at him with those heart shaped lips and his sister pleads him with those pretty eyes like her mother, Luhan caves. He caves because well, they deserve to know how they were made don't they? They deserve to know how they came from two worlds that were never supposed to be together. How love managed to overcome the worst of the worst between two races.

Aish, those two kids are really insufferable!
