So, there's monstly fics about Exo as wolves, but I wanted to do something different. I was inspired by my best friend to use mermaids/mermen because she has a thing for them. Since I used mermaids/mermen and they are mythical creatures, it was hard to keep everything politically correct. On another note, I don't hate Krystal, I just used her as a character because she's appeared as the antagonist in many other fics I've read. Also, I don't know why I didn't use Kai's real name; probably because I usually write at night before bed. The only thing I didn't like about writing this, was that I couldn't picture their faces as I wrote it, and usually I can with other things I read/write. I took a long time on this story, so I hope everyone enjoys it!
